5. Additional information
  • Because the motorcycle starter lever accessories are made of pig iron forgings and the material is very hard, ceramic media with heavy cutting force is used to roughly remove scale and burrs. In order to fully finish the corners of the parts or the toothed inner wall of the inner ring, the shape of the ceramic media is a chamfered cylindrical tumbling deburring media, and the smooth curve of the cylinder itself can have a smooth surface on the starting rod. Smoother polishing effect. It should be noted that if the starting rod is made of aluminum forgings, then our tumbling finishing media cannot use ceramic media, but needs to use softer materialResin media (also called plastic media).
  • These motorcycle parts are not afraid of hitting each other, so in order to improve the screening efficiency, the finishing machine uses the vibrating bowl finisher with separator.
  • Iron workpieces are easily oxidized again when exposed to water and air. Therefore, we need to dry the water immediately after finishing and polishing.

6. Final summary
  • In this case, we demonstrate the process of deburring and descaling on the surface of a forged motorcycle workpiece, also called a starter lever, starter rod, and spark lever, and further improving the surface gloss and brightness.
  • This process is also suitable for polishing parts and components such as automobiles, bicycles, fishing gear, pumps and valves, sewing machines, equipment and tooling produced from forged iron.

Can plasma finishing and polishing achieve a mirror polishing effect?

Plasma polishing has been widely used in fine polishing applications of high-end products, such as furniture and bathroom tableware industry: handles, handles, faucets, copper parts; glasses industry: glasses frames, glasses frames; aerospace manufacturing: aircraft engine blades; medical device manufacturing Industry: titanium alloy, stainless steel equipment and other fields.

1. What is plasma polishing?

Plasma polishing, also known as nano-polishing, is a new finishing and polishing process for deburring, descaling, and improving brightness on the surface of metal product workpieces. In essence, it is also electrolytic polishing. Under the action of large current, the electrolyte is vaporized and high-energy plasma is generated to impact the surface of the product to achieve a polishing effect. It is suitable for large quantities of special-shaped workpieces with complex curved surfaces to quickly and efficiently achieve a near-mirror polishing effect. So what kind of surface polishing effect can plasma polishing achieve? Today we will share a case in which deep-drawn stamping parts made of 304 stainless steel were treated with plasma polishing to remove burrs and oxide scale to achieve mirror polishing. Take a look at the specific advantages and disadvantages of this process and whether it can meet your finishing and polishing needs.
Let’s take a look at the comparison of the effects of plasma polishing on this stainless steel stamping part:

Surface effect of stainless steel deep-drawn stamping parts before plasma polishing

Surface effect of stainless steel stamping parts before plasma polishing(nano-polishing)

We can see that the surface of the original surface of this workpiece has lines left after cold rolling, and there are obvious stretch marks left after stretching on the edges. The upper opening has obvious burrs left after punching and cutting. It feels prickly and can cut your skin if you’re not careful.

Now the surface of the product is shiny, and the oxide scale on the internal and external surfaces has been removed. The original cold rolling marks are almost invisible when viewed from the front. The stretch marks on the edges have also become much reduced. The upper opening feels better to the touch. It should be smooth, no tingling feeling, and the burrs should have been removed.

2. Scope of application of plasma polishing

Now we fix the stainless steel deep drawing stamping part on the hanger and put it into the plasma polisher. After waiting for 2 minutes, you can see that its surface is now shiny and the original oxide layer has been completely removed. We Let’s take a look at the overall surface condition. The cold-rolled marks on the surface of the original part before polishing is still quite obvious. Look at the stretch marks on the edge. You can still see the obvious stretch lines. Let’s touch the cut part at the opening, the hand feels relatively rounded, does not irritate the hand, and the burrs have been removed. The internal and external surfaces of the entire product have uniform polishing quality and high brightness. It should be said that it is quite beautiful. Let’s sum it up. If your products are small pieces with relatively small burrs, smooth original surfaces condition, complex shapes, and large quantities, then plasma polishing can meet your needs and achieve a mirror polishing effect. If you want to remove larger burrs, flashes, scratches, and thicker oxide layers through plasma polishing, then plasma polishing cannot meet your requirements. Friends, do you now understand the characteristics of plasma polishing?

Finishing process method for deburring, deflashing, trimming from plastic rubber silicone and nylon product parts

How to remove burrs,flash and finish plastic, rubber, silicone and nylon product parts?

During the injection molding process of rubber, plastic, silicone and nylon products, due to mold, process or raw material reasons, a large number of burrs and flash often occur on the edge of the product or in the inner hole. The existence of this burr phenomenon will have a negative impact on the surface quality of the product. The commonly used and simple method of deburring and trimming is to use a scraper for manual processing. Of course, this is only suitable for a small number of products. If large quantities of automated mechanical processing are required, since rubber, plastic, silicone, and nylon products are soft and tough, Conventional vibration/barrel finishing, electrolysis, plasma, and magnetic processes cannot achieve satisfactory results. Today we will share a case of how to deburr, deflash from rubber shin guard products to achieve high-efficiency trimming in large quantities. This finishing process is also suitable for trimming requirements of other plastic, polyester, silicone, nylon, aluminum alloy, zinc alloy and other product parts with soft, light and hard-to-break burrs such as mobile phone cases, watch bands, O-rings and other plastics.

5. Additional instructions
  • Due to process limitations, rubber, aluminum alloy, zinc alloy and other products made by injection molding, casting and other processes often have a long layer of burrs around them after molding. This kind of burr is very thin, easy to bend, and has a certain degree of toughness, so simple mechanical and physical removal methods are not effective. Nowadays, a special deburring and trimming machine for rubber and plastic products is used to place the workpieces in batches into a special barrel and roll them. During the processing, liquid nitrogen is added to reduce the surface of the workpieces to more than 100 degrees below zero in a short time, making the edges of the workpieces The burrs and flash will become brittle and broken, but the body of the workpiece will not be affected. While the workpiece is rolling, it is supplemented by high-speed moving plastic elastic sand abrasives that impact the surface of the product, which can accelerate the removal of burrs and rough edge on the edges of the product or inside the holes to improve the surface effect.
  • Another thing to note is that in order to test different processes, we divided the sample into four small pieces and finally determined the optimal deburring plan.

6. Final summary
  • In this case, we demonstrate an automated finishing and trimming process that uses a freezing process to remove burrs and flash from the outer surface and internal holes of rubber shin guards.

Finishing and polishing of titanium alloy engine connecting rod parts

Titanium alloy connecting rods are used in the engines of many sports vehicles due to their high strength and excellent performance. Light weight but high durability are the outstanding advantages of titanium connecting rods.
This kind of engine parts generally uses a vibrating finishing and polishing machine to perform polishing processes such as deburring, descaling, deflashing, chamfering, and brightening. The main polishing process is divided into two processes: rough finishing and fine finishing.
Rough finishing uses high cutting strength ceramic tumbling media combined with chemical finishing liquid, and fine finishing uses high density stainless steel media combined with acidic chemical polishing liquid to improve the surface brightness of the product.

Finishing and polishing of cast iron engine piston and connecting rod accessories

Finishing and polishing of cast iron engine connecting rod parts

Engine connecting rods made of cast iron are weaker than those made of stainless steel. Generally, low carbon steel is used for production. The main advantage of this product is the low material cost.
A Vibratory Finishing Machines is also used for rough finishing and fine polishing. For coarse finishing, ceramic tumbling media and finishing liquid are used to remove burrs, oxide scales, and flash edges. For fine polishing, stainless steel polishing media and acidic polishing liquid are used to brighten the surface.

Machined engine piston connecting rod accessories finishing and polishing

Finishing and polishing of machined engine piston connecting rod parts

Machined connecting rods can be made from different materials of metal or alloys. This kind of connecting rod will bear high pressure in the engine, so good finishing and polishing of the product surface can repair some surface defects such as cracks, pits, burrs, flashes, etc. to ensure that the connecting rod will not break under pressure.
A vibratory polishing machine can be used for polishing. If the volume and quantity of workpieces are small, a Centrifugal Barrel Finishing Machine can also be used. Different metal or alloy materials require different finishing and polishing abrasive media.

Finishing and polishing of forged engine piston connecting rod accessories

Finishing and polishing of forged engine piston connecting rod parts

Forged connecting rods are stronger than cast iron connecting rods. The surface of the forged connecting rod is definitely rough and not smooth, so the finishing process of deburring and descaling is necessary.
Universal vibratory finishing and polishing machines can be used for surface finishing and polishing. If you pursue short time and high efficiency, you can also use a centrifugal barrel finishing machine. It’s just that the purchase cost of the machine is higher than that of the vibration machine.
The abrasive media need to be matched according to the material and the shape and size of the workpiece.

Aluminum alloy or zinc alloy engine piston connecting rod accessories finishing and polishing

Finishing and polishing of aluminum alloy engine piston connecting rod parts

There are many benefits to using aluminum alloy or zinc alloy connecting rods compared to cast or forged connecting rods. Although its strength is not as strong as connecting rods made of other materials, this connecting rod can improve shock absorption performance and help reduce stress damage to the engine crankshaft.
Vibrating finishing machines or centrifugal barrel finishing machines can be used to debur, descale and deflash. Tumbling media, there is no doubt that Resin Media（Polyester/Plastic Media）must be used，For polishing brightness, Porcelain Media, High Density Porcelain Media, orStainless Steel Media can be used.

Finishing and polishing of supercharged engine piston and connecting rod accessories

Finishing and polishing of supercharged engine piston connecting rod parts

This type of connecting rod needs to have strong fatigue resistance. Can be produced in different metals or alloys.
A slight defect on the surface of the product may lead to substandard quality, so finishing and polishing is a necessary process. We also recommend using a vibratory finishing and polishing machine.

  • 1. What part of the engine is the connecting rod?
  • The piston connecting rod belongs to the category of automotive parts and is an essential accessory for an engine. It is installed between the piston and the engine crankshaft. Also called connecting rod assembly. It is responsible for converting the linear motion of the piston into the rotational motion of the crankshaft.
  • 2. What is the function of finishing and polishing engine connecting rods?
  • Polishing your engine connecting rods has many benefits:

    2.1 Fine finishing and beautiful surface.
    The correct polishing process can give the connecting rod a beautiful surface treatment.

    2.2 Improves the durability of connecting rods.
    Finishing and polishing can remove burrs and scale from the surface of the connecting rod, which are key quality defects that affect the life of the connecting rod. Therefore, removing these imperfect surface defects through finishing and polishing methods can greatly improve the durability of the connecting rod.
  • 3. Can you explain how traditional engine connecting rods are polished?
  • The traditional way of polishing connecting rods is manual. It requires a lot of labor and is an annoying process.
    They all use a polishing wheel. Polishing heads of different sizes can be installed on this polishing wheel. According to the different connecting rods, different polishing heads can be replaced for operation. It is also necessary to use polishing paste to speed up the polishing process and make the surface of the connecting rod shiny.
  • 4. How is ShineTec’s engine connecting rod polishing machine polished?
  • Generally speaking, it is divided into two processes. The first is rough finishing, deburring and descaling. Just put your connecting rod blank and tumbling abrasive media into the machine, and then add an appropriate amount of finishing liquid and clean water. After the rough finishing process is completed, the connecting rod can be taken out and transferred to the fine polishing process, which uses polishing to improve the gloss and brightness of the product surface. Just put the connecting rod and the porcelain abrasive media for fine polishing into the machine, add an appropriate amount of polishing chemical liquid and water, and start the machine. The entire polishing process is fully automatic, and you can get a shiny finished connecting rod after the polishing is completed.
  • 5. What are the benefits of using ShineTec’s finishing and polishing machine to polish engine connecting rods?
  • The benefits are many:

    5.1 Excellent surface quality. The traditional manual polishing method depends on the skills and skilled procedures mastered by the workers. The finished products polished by each worker will result in different surface polishing quality, and it is difficult to achieve consistent surface quality of the finished products.
    Polishing with our ShineTec finishing machines can avoid these problems and achieve consistent surface polishing quality.

    5.2 Save man-hours. Polishing each piece by hand requires many man-hours. A worker can only handle one piece of connecting rod at a time. Using ShineTec’s engine connecting rod deburring and descaling solutions, large batches can be processed fully automatically at one time. The operating hours are greatly reduced.

    5.3 low cost. Finishing and polishing mainly consist of two costs. One is the purchase cost of machinery and equipment, and the other is the labor cost of polishing. Manual polishing requires a large number of workers, but using our ShineTec professional finishing machine to polish large quantities of connecting rods only requires one operator. The one-time setup cost of the equipment will be higher than manual polishing tools such as polishing wheels, but it can be used for a long time. The tumbling ceramic media can generally be used for several months or even years after purchase. They are not more expensive than grinding wheels and polishing heads. The key is This saves a lot of labor costs, and overall, the cost of polishing will be greatly reduced.

    5.4 No specially trained polishing operators are required. Hand polishing requires extensive training of operators upfront. Using our mechanized high-volume automated finishing and polishing solutions is simple and requires no dedicated employee training.

    5.5 Not a labor-intensive polishing process. Traditional manual polishing is a typical labor-intensive process and requires a lot of labor. The polishing process of engine piston and connecting rod parts provided by ShineTec is completely mechanized. Only one worker is required to control the machine’s switch, which greatly reduces the use of labor.

    5.6 Non-destructive surface polishing process. The quality of hand polishing depends on the skill of the polisher. Because manpower is uncontrollable, sometimes the polishing process may inevitably cause damage to the product surface. Using ShineTec’s finishing and polishing process, as long as the correct process flow and tumbling ceramic media are determined through process samples in the early stage, the final product of the engine connecting rod will have a uniform surface quality.

    5.7 Extremely low maintenance costs.
    When determining the polishing process for engine connecting rod accessories, routine maintenance costs are also an important factor that should be considered. ShineTec’s deburring and polishing machines are easy to use and operate and do not require additional special tools or trained operators. Therefore, daily maintenance costs are extremely low.

    5.8 Large batch processing. ShineTec’s engine connecting rod polishing machine has the capability of mechanized processing of large batches at one time. It can not only polish the same products in batches, but also deburr and polish connecting rods with different shapes and sizes in the same batch. It can be called an engine connecting rod polisher.
  • 6. Can you explain the differences between polishing by different finishing machines?
  • ShineTec’s finishing and polishing machines mainly have three common types that can be used for professional polishing of engine connecting rods. It can meet the needs of deburring, descaling, degreasing, deflashing, polishing and brightening.

    6.1 Vibratory Finishing Machine。 The vibrating finishing machine is the most commonly used machine for polishing engine connecting rod parts. This model is the easiest to use and operate. The high-strength and elastomer PU lining of the working chamber can protect the connecting rod and tumbling ceramic media from hitting and cutting the inner wall iron plate. It is the most cost-effective and economical engine connecting rod polishing process solution. It can feed large quantities of connecting rods at one time and is suitable for polishing small and medium-sized engine connecting rods.

    6.2 Rectangular Tub Finishing Machine。 Vibratory rectangular tub polishers can be used to polish long wishbones and crossmember links. The rectangular working chamber can be divided into several independent spaces with partitions, so that each connecting rod can be polished in a separate space without collision damage.

    6.3 Centrifugal Barrel Finishing Machine. The centrifugal barrel finisher relies on centrifugal force to drive the working barrel for polishing. It is mainly used to clean and polish connecting rods during the fine polishing stage. The polishing efficiency of this model is very high, and it can produce a mirror-like polishing effect on the surface of the connecting rod within half an hour. Centrifugal barrel finishing machines are divided into two types according to different loading and unloading methods. One is that the barrel has a relatively large capacity and cannot be removed. There is a sealing cover on the barrel, and loading and unloading tumbling media go directly through the opening of the barrel. The other is that the working barrel has a small capacity and can be taken out of the machine. The loading and unloading tumbling media are in the machine. Performed externally, suitable for smaller sized connecting rod polishing.
  • 7. Are there any differences in finishing and polishing between the different abrasive media provided by ShineTec?
  • The abrasive media used to remove burrs, scale and flash from engine connecting rods are also called ceramic tumbling media or polishing media. Each abrasive media corresponds to a different polishing process. Ceramic deburring media are generally used for deburring, deflashing, and descaling. Stainless steel media or polishing porcelain media and high-density porcelain media are generally used to improve brightness. For different shapes and sizes of connecting rods, each tumbling media has different shapes and sizes to choose from.

    7.1 Ceramic Deburring Media. Deburring media is made by mixing brown corundum sand with cutting force with clay, alumina powder, etc., and then sintering it in a high-temperature kiln after shaping. According to the different particle sizes of brown corundum sand, it is divided into heavy cutting, medium cutting and light cutting types, which are suitable for different materials. To measure the quality of a deburring media, there are several indicators such as cutting force, wear resistance, dimensional consistency, hardness, and color difference. The ceramic media produced by ShineTec all use the best first-grade brown corundum new sand, clay raw materials from major manufacturers in the industry, strict molding production processes, and proper sintering temperature control. The above indicators of the tumbling ceramic media are all Ahead of domestic peers. Especially in the key indicator of wear resistance, it is far ahead of competing products. The use time can be extended by 2-3 times, which can save a lot of consumable costs for the manufacturers.

    7.2 Resin Media. Also called plastic media, polyester media, it is obtained by mixing brown corundum sand with resin and curing it. There are also three different finishing levels, heavy cutting, medium cutting, and light cutting. Commonly used shapes include cone, triangle, tetrahedron, and bullet shape. This kind of tumbling finishing media is suitable for polishing soft parts made of aluminum alloy, zinc alloy, copper and other materials.

    7.3 Porcelain Media. This kind of tumbling abrasive media is mainly made of sintered kaolin and alumina powder. It does not contain brown corundum sand and has no cutting force. Therefore, it is mainly used to polish the surface brightness. That is the last fine finishing and polishing process. The quality of the product is mainly determined by the alumina powder content, which ranges from 30% to 70%. The higher the content, the greater the density and specific gravity, and the higher the gloss and brightness of the polished product surface. Of course, sintering temperature is also a key factor affecting quality. Like brown corundum abrasives, tumbling porcelain media have various shapes, including sphere, triangle, oblique triangle, right cylinder, oblique cylinder, three-star, oblique three-star, ellipse, etc., and the specifications and sizes also vary widely.

    7.4 Stainless Steel Media. Since the specific density of stainless steel can reach 7.8 grams/cubic centimeter, which is three times that of porcelain media, the surface of the polished product has the highest density and the highest brightness. Suitable for surface polishing of hard metals. Not suitable for soft metal workpieces such as aluminum alloys and copper. This polishing media has virtually no wear and can be used continuously for decades. The stainless steel media shapes include ball, ballcone, ufo, and pins shapes, and the materials include AISI201, AISI304, AISI316, AISI420, and AISI440C, which are suitable for different acidic or perishable environments.

    7.5 Walnut Shells or Corncob Media. Walnut shell or corncob media is a biodegradable vegetable abrasive. It is mainly used for the drying process after polishing the engine connecting rods. This tumbling abrasive media also comes in different sizes depending on the particle size. In addition to absorbing water and drying, it also has the ability to adsorb impurities and dust on the surface of the connecting rod to the abrasive, playing a cleaning role. It is a dust-free cleaning process.
  • 8. Are there any engine connecting rods that can be polished using ShineTec’s polishing machine?
  • ShineTec’s mass finishing machines are suitable for almost all types of engine connecting rods on the market.

    8.1 Titanium alloy connecting rod. Titanium alloy connecting rods are high-end products on the market because of their strength and durability. Its performance is unmatched by other connecting rod products. A vibratory finishing machine can be used for cleaning and polishing.

    8.2 Cast iron connecting rod. Because it is mainly produced from low carbon steel, its strength is lower than that of stainless steel connecting rods. Due to its low production cost, it is the most widely used connecting rod product on the market. Vibratory finishing machines can be used for finishing and polishing.

    8.3 Machined connecting rods. The material can be produced from different metals, depending on the type of engine used. The most suitable machine is a centrifugal barrel finishing machine, which can quickly remove tool lines, burrs, and scale. A vibrating finisher can also be used.

    8.4 Supercharged engine engine connecting rods. Because it is used in high fatigue strength environments, high-strength materials will be used to produce this connecting rod. Generally used in high-horsepower heavy-duty engines. Proper polishing process can repair surface defects and extend the service life of connecting rods. Suitable for polishing using a centrifugal barrel finishing machine.

    8.5 Forged engine connecting rods. Compared with cast iron connecting rods, forged connecting rods have higher durability. The tighter metal crystal structure formed inside the forged parts ensures higher strength of the product. But forged connecting rods have more surface imperfections. Vibratory or centrifugal barrel finishing machines can be used to polish this product.

    8.6 Aluminum alloy connecting rod. Aluminum alloy connecting rods have better shock absorption performance. It can reduce the stress on the engine crankshaft and extend its service life. Because it is a soft metal, the tumbling finishing media used for deburring, descaling must be a resin tumbling media. The mass finishing machine can be a vibratory finishing machine or a centrifugal barrel finishing machine.

The production and manufacturing process of vibratory finishing machines

Let’s take a look at how a Vibratory Finishing Machine changes from a steel plate into a polishing artifacts for deburring and descaling.

Vibratory finishing machine production process
  • 1. Blanking

    The purchased steel plates of standard sizes are cut into small iron plates according to the sizes of different machine models. The factors that affect the quality of machine products in this link are the quality and thickness of the steel plate. Our steel plates are all from the large factory of Shanghai Baosteel, with uniform thickness, and are all 4mm thick plates.
  • 2. Forming

    The cut steel plate is rolled into a cylinder with a plate rolling machine, which is used as the base of the machine and the barrel-shaped cylinder in the middle of the working chamber for installing the motor. Another main component is the bowl-shaped working chamber of the machine, which is pressed out using a hydraulic press and a special mold. In this way, the main components of the machine frame are finished.
  • 3. Welding

    This process is to weld the two ends of the rolled cylinder just now, and at the same time weld the bottom heel under the base to assemble the support of the vibration spring. This process can also affect the quality of the machine. Because the welds are not up to standard, problems such as cracking and falling off may occur during future use.
  • 4. Inspection and Finishing

    Check the surface condition of the weld, remove welding slag and oxide scale, use a grinder to grind the weld, and polish flash and burrs. Everyone knows that details are the devil, especially in the production process of industrial products, some seemingly inconspicuous small details often determine the final quality of the product. Blisters, small cracks in welds, flash and burrs on the surface of accessories will ultimately determine the appearance quality and service life of the machine.
  • 5. PU Casting

    Lining the inner wall of the hydraulically formed working tank with wear-resistant polyurethane colloid is the task of this process. During casting, a mold with a diameter smaller than the external frame body should be placed in the chamber, the external frame body and the mold should be fixed, and then the hot-melted PU glue should be poured into the gap between the frame and the mold. After the colloid cools and solidifies, it can be removed. After molding, the working chamber lined with PU glue is ready. This link is a key process that affects the service life of the machine. The wear resistance, thickness, and hardness of PU glue are factors that affect the length of use. Our polyester raw materials are all products from Dow Chemical (DOW) in the United States, and the casting thickness can reach about 15-20cm.
  • 6. Painting

    The next step is to spray paint on the surface of the working chamber and base, which can protect the iron plate and improve the aesthetics of the machine. Apply putty on the surface of the iron plate first to repair some obvious defects, such as pits, gaps, etc. After the putty dries, you can spray various beautiful colors.
  • 7. Assembling

    All required parts are ready. The next step is to put them together. First, a vibration motor needs to be installed in the middle cylindrical barrel of the machine. Install the motor to the base using a flange. The upper and lower ends of the motor are equipped with eccentric swing arm, commonly known as hammers. This is the main component for adjusting the direction and speed of the machine’s movement.
    Another major installation task is the installation of the base spring. Put the springs one by one on the support tubes on the base, so that the working chamber is suspended and supported on the base. The eccentric excitation force of the vibration motor will be brought to the chamber body to produce a spiral tumbling motion.
  • 8. Self Testing

    After all the installation steps are completed, it is the last step of power-on self-test. Connect the machine’s power cord to the control box and press the start button to start the machine. In this step, you need to check whether the direction of rotation and rolling of the machine is correct, whether the vibration frequency and amplitude are normal, whether there is any abnormal noise, and whether the installation and tightening bolts are loose. If everything is OK, it can be packaged and shipped.

  • 1. What is stainless steel media?
  • As the name suggests, stainless steel media are tumbling media made of stainless steel. This is a kind of mass finishng, tumbling polishing, brightening and smoothing abrasive media mainly used in the finishing industry.
    Stainless steel media act on your product parts and workpieces and have the functions of deburring, cleaning, degreasing, brightening, and mirror polishing. Most metal parts can obtain a shiny surface effect after polishing.
    High-quality stainless steel raw materials produce high-quality stainless steel media. They have a long service life and can be used for a long time. They are the best choice for tumbling, mass finishing and polishing processes. At the same time, the impact of stainless steel media can improve the surface strength of product parts and repair surface defects.

  • 2. What are the uses of stainless steel media?
  • Stainless steel media are widely used in the finishing and polishing industry of tumbling, vibrating, mass finishing and polishing. Specific applications are as follows:

    2.1 Deburring. Stainless steel media also have the function of removing burrs. Some small burrs and sharp teeth on the edges of parts and hole walls can be chamfered and flattened by scraping with stainless steel media with sharp corners or edges to achieve the effect of removing burrs.

    2.1 Turning tool marks removing. This process is similar to deburring. The turning tool marks left after the machining of parts can be removed by the impact and scraping of stainless steel media.

    2.2 Polishing. The main function of stainless steel media is to brighten the surface of product workpieces. Through the tumbling and rotating motion of the machine, the high density stainless steel media impacts the surface of the part, changing the metallographic structure of the metal surface layer. The arrangement of the metal grains is reorganized to form a dense layer, which enhances the diffuse reflection of light, making the surface Becomes shiny and sparkling, achieving a near-mirror polished effect.

    2.3 Degreasing. Through the combined use of stainless steel media and cleaning liquid, dust, sludge, and grease on the internal and external surfaces of parts can be removed. Manual cleaning of oil stains is a time-consuming and labor-intensive process. Using a tumbling finishing machine and stainless steel media for cleaning can improve the brightness and gloss of the surface of the parts while removing oil and stains. It is a process that gets twice the result with half the effort.

  • 6. Which parts can be polished with stainless steel media?
  • If your product parts are made of metal and have a hardness equal to or less than 304/302 stainless steel, then polishing with stainless steel media is the best choice. While polishing, stainless steel media can also remove surface oxide scale, turning tool marks and other defects on brass, copper, aluminum, zinc and other products.
  • 7. How do stainless steel media polish product parts?
  • Put the stainless steel media into the working barrel of the finishing polishing machine, add water and an appropriate amount of polishing liquid. After the machine is started, the stainless steel media and the workpiece will have a tumbling and rotating motion in the machine. The abrasive media and the parts rub against each other, which will cause the surface to change. Scrape off the scale, burrs, residue, etc. In addition, stainless steel media have an impact force on the parts, which will change the grain structure arrangement on the surface of the parts, forming a dense layer and achieving a shiny surface effect.
  • 8. What is the best stainless steel media?
  • The best stainless steel media should look like this:
    Fully self-grinding, the curved surface is round and smooth, and the cut surface is neat and straight.

  • 9. Which finishing and polishing machine is suitable forv stainless steel media?
  • ShineTec recommends using a vibratory polishing machine with stainless steel media for polishing. The reasons are as follows:

    9.1 To achieve a good polishing effect with stainless steel media, the product parts need to be put into as much tumbling media as possible. The vibratory finishing machine can be equipped with a high-power vibration motor and a large-capacity working chamber to obtain a larger amplitude, allowing the workpiece to fully tumble in the machine and collide with the abrasive media to obtain a better surface effect.

    9.2 Because the size of the centrifugal barrel is limited, the centrifugal barrel finishing machine has a small loading capacity of tumbling media and is not very efficient. Moreover, due to the large proportion of stainless steel media, the centrifugal force generated when the barrel is loaded with abrasive media and rotates at high speed will increase many times, which greatly exceeds the design strength of the centrifugal barrel finishing machine and creates potential safety risks.

    9.3 The barrel of the centrifugal disc finishing machine also does not meet the capacity requirements compared to the vibrating finishing machine. If it is operated at full load, it will greatly exceed the design strength of the machine, and it is not suitable to use stainless steel media to polish product parts.

    9.4 The polishing efficiency of the tumbling barrel finishing machine is too slow, and the design capability of the machine itself is not suitable for heavy-duty use, and it is not suitable for polishing with stainless steel media.

  • 10. What are the benefits of polishing with stainless steel media?
  • If you don’t know how to improve the surface gloss and brightness of metal product parts and workpieces, then using stainless steel media for tumbling and polishing is the best polishing process and method.

    10.1 High polishing efficiency. Compared with polishing media such as high-alumina porcelain media, high-density porcelain media, and zirconia balls, stainless steel media have the highest specific density (7.8 g/cm3) and can obtain the highest brightness in the shortest time.

    10.2 High cleaning efficiency. Stainless steel media have very little wear and do not pollute the surface structure of metal product parts. With the assistance of cleaning agents and brighteners, they can fully clean away oil, sludge, and impurities on the surface of workpieces automatically, in large quantities, quickly, and solve the problem of manual cleaning. Time-consuming and labor-intensive problem.

    10.3 Non-destructive polishing. 不Stainless steel media have no cutting force, will not finish the surface with great force, and will not affect the dimensional accuracy of the product. It is a non-destructive polishing process.

    10.4 Extra long service life. Stainless steel media have almost no wear, and a single purchase can last almost a lifetime. There is almost no wear cost, which can greatly reduce your direct polishing costs.

    10.5 Easy to use. Ceramic polishing media will stick to each other, break, and become dirty after use. They need to be fully self-polished and cleaned before they can be used again. There are no breakage or bonding issues with the stainless steel media. After polishing, you only need to simply rinse it with water and it can be used continuously again.
  • 11. Do stainless steel media require maintenance for daily use?
  • Good maintenance habits can extend the service life of stainless steel media. Although stainless steel media is an tumbling polishing media that is easy to use and store, its service life will be accelerated if not properly maintained.

    11.1 Correct usage. After polishing, if it is not used for a long time, you need to rinse the stainless steel media with water and dry it before storing it.

    11.2 Proper mixing ratio of stainless steel media, product parts and polishing liquid. A corresponding ratio needs to be maintained among the above three. In order to save procurement costs, many people want to use as little stainless steel media as possible and put more product workpieces. However, too little abrasives will cause the product parts to collide with each other during polishing or the workpieces to directly scratch the working chamber wall of the machine and damage the lining PU. This results in reduced polishing efficiency, reduced polishing quality and possible damage to product parts and machines.

    11.3 Replacement of damaged stainless steel media. Ensure that every one of stainless steel media in the machine is intact. If some of the media are deformed or damaged, the damaged media must be replaced immediately. The damaged media surface will produce cracks, edges, and cutting edges. These parts will affect the surface effect of product parts during polishing, and even damage the product.

  • 12. In which industries can stainless steel media be used for product parts and workpieces?
  • Stainless steel abrasives can be used for finishing and polishing metal parts or workpieces in most industries.

    12.1 Professional finishing and polishing processing job shop. Stainless steel media are the most cost-effective tumbling media in the polishing process of polishing job shop. There is no wear on the abrasive, and only a small amount of chemical polishing liquid needs to be added for each processing to complete the polishing process. This abrasive media is available in many polishing processing job shop.

    12.2 Jewelry industry. After long-term storage or use, the surface of jewelry will produce an oxide layer, which will darken and turn black. Polishing with stainless steel media can restore jewelry to its original luster.

    12.3 Auto parts industry. The auto parts industry is an area where stainless steel media are widely used. Includes deburring and polishing applications. Such as engine cylinder heads, pistons, motorcycle wheels, mufflers, fasteners, gears and other products. It also has a good polishing effect on the refurbishing of some forged or cast auto parts.

It can completely remove the oxide layer on the surface, eliminate cracks and other defects on the surface of parts that are easily affected by oxidation, and improve the overall corrosion resistance.

    13.2 Improves strain hardening of parts. After tumbling finishing and polishing with stainless steel media, the surface hardness of the parts can be increased. Compared with unpolished parts, the surface hardness can be increased by 50-100%.

    13.3 Brightening and burnishing effect. Stainless steel media can not only improve the strength of parts, but also improve the brightness and gloss of the product surface. After the fine polishing process, it can achieve an effect close to mirror polishing.

  • 14. How long is the service life of stainless steel media?
  • If you take appropriate daily maintenance measures, you can use it for a long time. Of course, poor usage habits will definitely reduce the use time of stainless steel media. In comparison, compared to porcelain polishing media, its service life is far longer than other abrasive media.
  • 15. Can brass parts be polished with stainless steel media?
  • Yes, brass parts can be polished with stainless steel media.
  • 16. Can nickel-plated metal parts be polished with stainless steel media?
  • Yes, stainless steel media can be used to polish nickel plated metal parts. However, the polishing time needs to be shortened to 40-60% of the ordinary polishing time.
  • 17. Can stainless steel media be used for dry and wet finishing?
  • Stainless steel media cannot be used for dry polishing. During the polishing process of product parts, metal shavings, oil stains and other impurities will be produced. If these sludge is not cleaned during the finishing process, it will adhere to the surface of the product to form a layer of oil stains, making the parts black and dull. The result is that the workpiece will become darker. The darker you throw it, the brighter it will never be.
  • 18. Do stainless steel media need to be dried when stored?
  • If you need to store it for a long period of time, such as months or years, you need to let the stainless steel media dry before packaging and storage. If it is for a short period of time, it is not necessary because stainless steel itself is rust-proof and anti-corrosion.
  • 19. Will stainless steel media damage my parts?
  • As long as the proper matching ratio of media, water, and polishing liquid is maintained during the polishing process, and the size of the media matches the size of the parts, there will be no damage.
  • 20. Do stainless steel media require special lubrication?
  • Unnecessary. When polishing with stainless steel media, you only need to add clean water and an appropriate amount of polishing liquid. There is no need to add external lubricating grease and other substances.
  • 21. Are stainless steel media magnetic?
  • Yes, stainless steel media are weakly magnetic. You can use this feature to use magnets to collect media scattered on the floor around the machine during the polishing process.
  • 22. What are the proportions of media, parts, and water when polishing with stainless steel media?
  • Generally we recommend this matching rate:

    Media : Parts : Water = 3 : 1 : 2

  • 23. Where should stainless steel media be placed when stored?
  • Please place stainless steel media in a dry, clean indoor space. Although stainless steel media themselves are anti-corrosive and anti-rust, low-grade materials will also rust if they are exposed to humid, acidic and alkaline environments for a long time.
  • 24. How long does it usually take to polish with stainless steel media?
  • It usually takes about 30 minutes to polish with stainless steel media. If the surface brightness does not improve significantly after more than 1 hour, extending the polishing time will have no effect.
  • 25. Can jewelry be polished with stainless steel media?
  • Yes, jewelry can be polished with stainless steel media.
  • 26. Why does the surface of the part become darker and lose its luster after being polished with stainless steel media?
  • When polishing with stainless steel media, it is found that the surface of the part becomes black and dark because the oil on the surface of the media or the carbon in the impurities is deposited on the surface of the product. The solution is to clean the stainless steel media with cleaning liquid before polishing.
  • 27. Which stainless steel media should I buy?
  • 27.1 Choose the appropriate stainless steel media according to the shape and size of your product parts and workpieces. Please do not use large-sized media to polish small-sized parts to avoid damage. If you use small-sized media to polish large-sized parts, it will take more man-hours and have a big impact on the service life of the media.

    27.2 Make sure that the internal and external surfaces of your parts, as well as holes, gaps, corners, etc., can be polished with stainless steel media.

    27.3 According to the actual usage environment of your product. If your use environment contains acid and alkaline substances, you need to choose high-grade stainless steel media. The following is the corrosion resistance of various grades of stainless steel media:

    440C < 420 < 302 < 304 < 316
  • 28. Why do my product parts turn black after being polished with stainless steel media?
  • The main reason is that the stainless steel media needs to be pre-cleaned before polishing. If there are some residual brighteners, sludge, debris and other impurities attached to the media surface after the last polishing, polishing again will contaminate your product parts with these impurities, causing the product surface to turn black.
  • 29. Do stainless steel media need to be cleaned before each use?
  • We recommend cleaning stainless steel media once before use. This ensures that the surface of the part will not turn black or dull during the polishing process.
  • 30. How much stainless steel media is required to complete a polishing process?
  • Depending on the machine capacity used. It is recommended that the total volume of materials does not exceed 2/3 of the working chamber.
    The general ratio of parts to media is 1:3, and this ratio can also be adjusted according to the shape and size of the workpiece.

  • 31. What is the best machine for polishing with stainless steel media?
  • We recommend using a vibratory polishing machine to polish with stainless steel media. The advantages are: easy to load and unload, you can check the polishing effect at any time, large loading capacity, and simple to use.
  • 32. Do stainless steel media need rust inhibitors?
  • Unnecessary. Because stainless steel media are made of anti-corrosion and anti-rust stainless steel materials, there is no need to add additional anti-rust liquid.
  • 33. Can other types of finishing machines be polished with stainless steel media?
  • Centrifugal disc finishing machines, centrifugal barrel finishing machines, and barrel tumbling finishing machines can all use stainless steel media for polishing. It’s just that other machines need to reduce the loading of media when polishing. Generally, the amount of media is reduced by half compared to using porcelain polishing media.
    tumbling polishing, brightening with stainless steel media
  • 34. Is polishing with stainless steel media faster than using other polishing media?
  • Yes, because the density of stainless steel media exceeds that of porcelain polishing media, it is easier to obtain a bright surface effect in a shorter time.
  • 35. Can plastic parts and workpieces be polished with stainless steel media?
  • No. The material of plastic products is not suitable for deburring and polishing with stainless steel media. You can use ceramic deburring media or resin media to remove burrs, and use brightening media to polish the brightness.

About Resin Media

  • 1. What is resin media?
  • Resin media are also called plastic media, polyester media. It is a resin abrasive media specially used for deburring, descaling, deflashing, derusting, charmfering, finishing for product parts and workpieces made of soft metal or non-metallic materials.
    Parts made of aluminum, copper, zinc, plastic, acrylic and other materials have a soft surface texture. If they are finished with high-hardness tumbling media such as ceramic deburring media, they will leave scratches, pitting, etc. on the surface of the product. However, resin media It contains a large amount of resin, and its texture is soft and elastic, which can avoid such problems, so it is suitable for processing such products. This is also the advantage of plastic media.
    The hardness of resin media is much smaller than that of brown corundum, silicon carbide, white corundum and other ceramic media, and the cutting force will be smaller accordingly. It is also easier to control the cutting force for deburring some precision parts, and it is also a very good choice for such products.

    deburring,descaling,deflashing,derusting,finishing of resin media
  • 2. What are the main components of ShineTec’s resin media?
  • Resin media are made by mixing abrasive sand and resin in a certain proportion. Microsilica powder is the most commonly used abrasive sand for resin media, and there are also formulas that add zirconia, corundum sand, alumina powder, etc. Among them, the type, particle size and content percentage of abrasive sand are the key factors affecting the finishing and polishing effect. The larger the particle size and the higher the content of the abrasive sand powder, the greater the deburring strength of the polyester media, but it cannot be higher, because the larger the particle size and the higher the content of the sand powder, the lower the wear resistance and the service life. Therefore, it is best not to use resin media for heavy cutting for a long time.

  • 3. What can resin media be used for?
  • Plastic media, with their elastomer abrasive material properties, can be used in various surface treatment processes to create a low roughness on the surface of the part. It is an excellent process choice for surface pretreatment, finishing and polishing of product parts such as anodizing, coating, painting, and electroplating. The main functions are as follows:

    3.1 Deburring. The surface of product parts is finished to remove defects such as burrs, flash, edges, quick-cutting, pouring gates, etc.

    3.2 Descaling. When metal materials are exposed to the air for a long time, an oxide film will form on the surface. For example, iron will rust, aluminum will turn black, copper will develop patina, etc. Plastic media can be used to remove rust and scale from these products and restore the original luster of the metal.

    3.3 Turning tool marks removing. Machined parts can easily leave turning marks on the surface of the product due to wear of the turning tool or position adjustment. These marks can be easily and quickly removed using plastic media, but it will not affect the product’s appearance accuracy and dimensions.

    3.4 Degreasing. During the processing of parts, sludge, dirt and other dirt will adhere to the surface of the product. Manual cleaning is difficult to remove and inefficient. Using plastic media, water and finishing liquid to tumbling in a finishing machine can remove oil stains and quickly clean product parts.

    3.5 Fine finishing. Parts finished with plastic media can achieve very low surface roughness. On this basis, using stainless steel media, high alumina porcelain media, zirconia media or biological abrasive media, combined with the barrel polishing process, a very bright surface effect can be obtained, even close to a mirror polishing effect.
  • 4. How is resin media used for tumbling deburring and finishing?
  • Like the finishing method of other tumbling media, the vibration of the machine, high-speed centrifugal motion, eddy current rotation, barrel rotation, etc. are used to drive the plastic media to tumble and rotate together with the parts. The media rub on the surface of the product parts to remove the burrs and flash on the surface. Flash, oxide layer, rust spots, etc. are cut away to achieve polishing.
    Since the texture of plastic media is softer and more elastic than ceramic media, it will not cause damage to parts made of soft materials. It is especially suitable for deburring and finishing workpieces made of aluminum alloys, copper, zinc and other products.
    Plastic media finishing experience and problem solving is a process that requires long-term experience accumulation. If you don’t know how to quickly deburr and finish copper, aluminum, brass, handicrafts and other product parts to achieve the best results, what is the best brand of resin media you are looking for? Please contact us and ShineTec will provide you with professional consulting services.

  • 5. What are the different shapes of resin media?
  • ShineTec’s plastic media come in a variety of shapes and sizes. The main shapes are cone, tri-star, pyramid, tetrahedron, cannonball, triangle, etc.
    You need to choose the appropriate plastic media shape based on the shape of your product parts. Cones and tetrahedrons are suitable for finish general product parts and are more commonly used shapes. Cone and cannon-shaped (bullet-shaped) shapes are relatively smooth in appearance. Generally, the grooves, seams, holes, and holes of the parts will not get stuck during the finishing process. Other shapes have sharp corners. If the size is not selected properly, jamming will occur. If it gets stuck, it will take a lot of time to clean the blocked part.

    Plastic media such as tetrahedrons, triangles, and tri-star shapes can finish complex-shaped product parts. The sharp corners and edges of this type of abrasive media can reach hard-to-reach parts, and this is also the reason why plastic media are not wear-resistant (compared to for ceramic media). Sharp corners are easily damaged and broken during high-speed movement. In addition, the production process of plastic media is relatively simple. They are hardened by the curing reaction of resin and abrasive sand powder, and are sintered with ceramic media at a high temperature of 1,000 degrees. The difference is several times, and the wear resistance of plastic media is definitely not as good as ceramic media.

    The size of the plastic media is also a key factor affecting finishing quality. The contact area between small-sized media and parts is definitely smaller than the contact area between large-sized media and parts, and the surface treatment will be more delicate. Therefore, the finishing and polishing effect of small-sized media is better than that of large-sized media. Choose a larger size plastic media if you need to cut the part aggressively. Sometimes, you can also mix plastic media of different shapes and sizes together for use. This can be determined according to the actual condition of the part.

  • 6. Which finishing machine is resin media suitable for?
  • Polyester media are suitable for all ShineTec’s finishing and polishing machines. Vibratory finishing machines, centrifugal barrel finishing machines, centrifugal disc finishing machines, barrel tumbling finishing machines or automatic mass finishing system can all use polyester media for finishing and polishing.
  • 7. What industries can resin media be used in?
  • Polyester media have the characteristics of medium and low strength cutting performance, light and soft elastic impact force, and no pollution to the surface color of the workpiece. They are widely used in machining, precision molds, auto parts, aerospace, medical equipment, mechanical parts, plastic products, 3C digital, metal casting, electronic devices, hardware parts, kitchen supplies, 3D printing, textile workpieces, powder metallurgy, electrical components, minting, jewelry, instrumentation, handicraft accessories and other industries. With professional tumbling finishing machines, large quantities of product parts and workpieces can be efficiently removed from burrs, flash, sharp edges, rust spots, flattening, rounding and other surface treatments.
  • 8. Which parts are suitable for deburring with resin media?
  • The material with cutting force in polyester is abrasive sand powder such as silica powder and brown corundum, and the other main component is resin. Compared with ceramic media such as brown corundum deburring media and white corundum precision finishing media, the content of abrasive sand is lower, so polyester media are tumbling media with medium and low cutting force. It is most suitable for parts requiring medium to low cutting forces. It can be used very well to polish soft and fragile product parts. For example, workpieces made of copper, aluminum, zinc, brass and other materials.
    Polyester media can also be used to deburr hard product parts such as iron, stainless steel, and alloys. However, compared with brown corundum ceramic deburring media, the finishing efficiency will be lower, it will take more time to finish, and the media wear will be higher.
    For some small and medium-sized precision parts, fine finishing polyester media is the suitable finishing and polishing material. The cutting force generated by fine finishing polyester media is small, the impact on dimensional accuracy is subtle, and over-grinding will not occur.

    deburring with polyester media
  • 9. What is the difference between resin media and other tumbling media?
  • Polyester media, like other ceramic media such as brown corundum deburring media, silicon carbide deburring media, chrome corundum finishing media, and white corundum finishing media, can be commonly used in tumbling finishing machines such as vibrating, centrifugal barrel, disc, barrel finishing and smoothing. The main differences from other abrasive media are as follows:

    9.1 Differences in raw materials. In addition to corundum sand, ceramic media also include alumina powder, alumina, clay and other micro-powders. Except for corundum sand, all micro-powders naturally have a small amount of cutting force, so brown corundum deburring media can be made into heavy cutting forces. The main components of polyester media are silica powder, quartz powder, and polyester. The cutting force of these powdery sand powders is not as good as that of corundum sand, so the overall cutting force of the media is medium or light.

    9.2 Differences in production processes. Ceramic media are made from various micro-powders through processes such as mixing, vacuum mud refining, shaping, cutting, and sintering. The temperature of high-temperature sintering can reach about 1300 degrees, and the hardness of the finished product is close to that of natural stone. The production process of polyester media is to mix resin, silica powder, quartz sand and other raw materials, and then make them through batching, stirring, vacuum, gelling, curing molding, demoulding and other processes. The curing temperature is about 180~190 degrees. After the finished product It has certain elasticity and low hardness. How to make the polyester media wear-resistant is to test the production process quality control level of the polyester media manufacturer.

    9.3 Differences in minimum sizes. Spherical ceramic media, due to the rounding process, can have a minimum diameter of 1 mm, and for a triangular shape, with manual cutting technology, the side length can also be 2 mm. The polyester media is formed by mold casting, so the current smallest specification can be 6mm.
  • 10. How long is the service life of resin media?
  • The service life of resin media depends on your usage scenario, and there is no standard wear time. Factors such as the shape and size of the parts and the shape and size of the resin media will affect the wear resistance of the media.
    Resin media with sharp corners or edges will definitely have a shorter service life than media with smooth surfaces. Large-sized resin media are more wear-resistant than small-sized resin media and have a longer service life.
    If you find that the finishing time is much longer than usual, or the worn media often gets stuck or blocked, you need to replace it with new resin media.
    In short, compared with ceramic media, the wear resistance of resin media is much smaller, and the corresponding service life is also shorter. If you want to know where to find the best resin media or plastic media or polyester media, you might as well pay attention to our ShineTec’s resin tumbling media.
  • 11. What is the cost of using resin media?
  • 11.1 The price of resin media is generally more than five dollars per kilogram. As for the resin media themselves, the smaller the media, the more expensive they are. At present, domestic resin media all use manual molding, demoulding and other processes. The smaller the specifications, the lower the output, and the more expensive the price.

    11.2 The more complex the appearance, the more expensive the price. Of all shapes, the cone is the easiest to demold and therefore the cheapest resin media. Pyramid shape, using a lot of materials, low demoulding efficiency, and the highest price.

    11.3 Compared with brown corundum ceramic deburring media, because they have lower wear resistance, greater wear and tear, and are more expensive, the cost of use will be much higher.
  • 12. How to choose the appropriate resin media?
  • There are some factors to consider when choosing the right resin media:

    12.1 Determine the shape and size of the resin media. Make sure that the media does not get stuck or block the inner hole, and ensure that all parts of the internal and external surfaces of the part can be finished.

    12.2 If you want to use a small-gauge resin media, you may also consider adding some larger-gauge resin media. This mixing method speeds up the finishing process. The mixing ratio of large and small media can be a 2:1 ratio.

    12.3 Determine what your main needs are? If you use a large resin media, the finishing will be faster but the surface of the part will be rougher. If you are concerned about surface roughness and want a finer, smoother surface, use smaller media.

    12.4 Also consider that the size of the resin media can easily separate from the finishing and polishing parts. In other words, the size of the media must be significantly different from the size of the parts, otherwise the two will be mixed together and it will be difficult to separate them.

  • 13. What is the size of ShineTec’s resin media?
  • ShineTec can provide cone and tetrahedral resin media up to 100mm. Minimum size is 6mm pyramid and cannonball shaped resin media.

About Ceramic Media

  • 1. What is the ceramic media?
  • Ceramic media is used for tumbling finishing and polishing of product parts and workpieces, also called tumbler media, vibratory media, tumbling chip. It is a melting reaction between sand powder abrasives (such as brown corundum abrasive sand, white corundum abrasive sand, chrome corundum abrasive sand, silicon carbide abrasive sand, alumina powder, zirconia powder, etc.) and other ceramic bonding agents at high temperatures, artificially sintered mass finishing and polishing materials with various shapes. Because its hardness is close to that of stone, it is called tumbling stone. It can repair defects on the product surface, improve surface physical properties, and has a variety of finishing or polishing uses.

  • 2. What types of ceramic media are there?
  • There are many types of ceramic media, each suitable for different surface treatment purposes.
    Depending on the type of sintered abrasive sand powder, the commonly used ones are ceramic deburring media, silicon carbide deburring media, White corundum finishing media, chrome corundum finishing media, porcelain polishing media, High density porcelain media, zirconia polishing ball, Resin media.
    According to the use effect, there are rough finishing media, fine finishing media and polishing media. Both rough and fine finishing media have cutting force, but the cutting force is divided into light and heavy. The polishing media does not have cutting force and is only used to improve the surface gloss and brightness of the workpiece.
    According to the material, there are ceramic media and resin media. Among them, ceramic media are the collective name for deburring media such as brown corundum, silicon carbide, white corundum, chrome corundum, high-aluminum porcelain, high-density porcelain, and zirconia abrasive media.

  • 3. What is the use of ceramic media?
  • The operating principle of the ceramic media is to mix the workpiece or part with the tumbling media, add an appropriate amount of water and finishing compound, and load it into tumbling finishing machine In the working barrel, mechanical movements such as tumbling and rotation are carried out through vibratory (vibration), centrifugal disc, barrel, and tumbling barrel, so that the ceramic media and the workpiece impact and rub against each other, finishing the surface to achieve the effect of deburring and polishing.
    The role of ceramic media is reflected in two aspects:
    The ceramic media with cutting force can perform functions such as deburring, descaling, deflashing, chamfering, derusting, degreasing, cleaning and smoothing of parts and workpieces.
    The ceramic media without cutting force improves the density of the skin layer by impacting the product surface, and can polish and brighten the surface of parts and workpieces.

  • 4. How long is the service life of the ceramic media?
  • The service life of a ceramic media can usually be from a few months to a few years, depending on the hardness, shape, and size of the finishing workpiece. Workpieces with sharp burrs and edges, sharp edges, flash edges, higher hardness and larger appearance will cause greater loss to the media. The service life is shorter.
    Of course the most basic factor depends on the quality of the ceramic media. High-quality tumbling media will enhance wear resistance while ensuring finishing efficiency. ShineTec’s ceramic media is a mature and stable formula formed on the basis of dozens of process tests. Corundum sand and ceramic bonding agent have the strongest matching performance, and the wear resistance of the product is longer than other products on the market in terms of service life. There is a 3 times improvement.
  • 5. What are the different functions of ceramic media made of different materials?
  • 5.1 Brown corundum deburring media is suitable for finishing and cutting product workpieces made of general metal or non-metal materials such as burrs, oxide scales, flash edges, turning tool marks, cutting edges, mold closing lines, etc.

    5.2 Silicon carbide deburring media are suitable for finishing and cutting hard, highly brittle and low-strength materials, such as cast iron, brass, bronze, zinc, tin and other products, especially magnetic materials such as rubidium iron boron, with very good results.

    5.3 White corundum and chrome corundum deburring media are suitable for finishing and cutting some precision parts and components because of their fine grit size. Also, because of their low surface roughness after treatment, they also form a very bright surface effect, so It is often used to finish and polish these products in one process at the same time.

    5.4 High alumina porcelain polishing media do not contain abrasive sand inside, so they have no deburring effect. The main component is alumina powder. The abrasive has high density. When it moves with the workpiece, it has a strong impact on the surface of the workpiece, forming a thick surface dense layer, which can improve the surface gloss and brightness of the part.

    5.5 The function of high-density porcelain polishing media is the same as that of high-alumina porcelain media. The difference is that the content of alumina powder in high-density porcelain media is higher, and its alumina content can reach more than 95%. Therefore, the density is larger, forming the surface brightness is higher.

    5.6 There is no abrasive sand inside the zirconia polishing ball. The main component is zirconia powder. The density of the zirconia media is higher than that of high-density porcelain media. The surface brightness of the workpiece after natural treatment is the highest.

    5.7 Resin media contain abrasive sand inside. Depending on the grit size of the sand, they can be divided into heavy cutting, medium cutting, and light cutting. They are suitable for finishing some soft metal workpieces, such as aluminum alloy products.

  • 6. What is the finishing efficiency of the ceramic media?
  • The finishing efficiency of the ceramic media depends on the grit size of the abrasive sand contained in it and the type of deburring and finishing machine. Specifically in terms of finishing time, the time required for a single finishing treatment can range from a few minutes to a few hours.
    The larger the grit size of the abrasive sand, the stronger the cutting force and the higher the finishing efficiency. But the larger the grit size, the greater the surface roughness and therefore the worse the surface finish.
    Depending on the operation mode and speed of the tumbling finishing machine, the finishing efficiency can be arranged in the following order:
    centrifugal disc finishing machine > centrifugal barrel finishing machine > vibratory finishing machine > tumbling barrel finishing machine。
    In addition, for the same type of machine, the larger the machine, the larger the volume of the working barrel, and the higher the finishing efficiency.

  • 7. Does the shape and size of the ceramic media affect its finishing performance?
  • The shape and size of the ceramic media are key factors affecting finishing performance. The purpose of making the ceramic media into shapes such as triangles, cubes, spheres, cylinders, and three-star shapes is to make certain sharp corners, cut surfaces, and curved surfaces of the ceramic media better match the irregular and complex shapes of product parts, so that some parts that are difficult to reach can be parts can also be polished. If the selection of the ceramic media is incorrect, some parts will never be polished, which will definitely affect the finishing performance.
    The size of the ceramic media is also an important factor to consider. If the size is too large, it will also cause the inner holes, dead corners, gaps and other parts of the workpiece to be unable to be polished. If the size is too small, on the one hand, it will cause the abrasive to wear too fast, and on the other hand, it will block certain holes in the product, and may even result in defective products.

  • 8. What are the benefits of finishing and polishing with ceramic media?
  • Are you still looking for manual polishing methods? Let us recommend to you this large-volume, high-efficiency automatic finishing and polishing process. Its comparative advantages over manual finishing methods are as follows:

    8.1 Compared with manual finishing and deburring, the efficiency can be improved dozens of times. Using some large-scale tumbling finishing machines, ceramic media mixed workpieces can feed hundreds or even thousands of kilograms at a time, and can be completed within dozens of minutes or hours. This processing efficiency is incomparable to manual polishing.

    8.2 The surface effect after finishing is uniform and controllable. The quality of hand polishing depends on the personal skill proficiency of the worker. Some products may have burrs polished cleanly, while others may still have some residue. The surface quality of each product is different. Sometimes it may also cause product damage, resulting in a relatively high scrap rate.

    8.3 The running costs of tumbling finishing are extremely low. The one-time purchase cost of the machine starts from a few thousand dollars, and it can generally be used for many years. The choice of ordinary ceramic media depends on the actual conditions of the product parts that need to be processed, and the price ranges from a few dollars to more than ten dollars per kilogram. Buying a few hundred kilograms at a time can usually take several months. The amount of polishing compound is very small and the cost is almost negligible.
    Ordinary finishing machines can feed dozens of kilograms of workpieces at a time, and the finishing time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.
    On the other hand, in terms of saving labor costs, the advantage of using ceramic media for batch deburring and polishing is even greater. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

    8.4 By customizing ceramic media with special shapes and sizes, they can be used to process some deburring and polishing areas that cannot be completed by manual finishing. They have powerful functions and wide applicability.

    8.5 It is a safe and environmentally friendly deburring and polishing process. Compared with processes such as chemical polishing and electrolytic polishing, the sludge produced by ceramic media can be directly treated as solid waste after filter press, which is environmentally friendly.
  • 9. Can the ceramic media be used for dry finishing?
  • Not allowed.

    The water and finishing compound during the polishing process can provide lubrication. Buffer the impact force generated by the workpiece and ceramic media during high-speed movement. Without the lubrication and buffering effects of water and finishing liquid, the debris and impurities shed during the finishing process will scratch the surface of the workpiece and leave pits on the surface.

    At the same time, these metal or non-metal debris and impurities will accelerate the wear of the PU lining in the working barrel, greatly increase the temperature rise generated during work, and greatly reduce the service life of the PU.
    If the dust generated during the grinding process is not moistened with water, it will produce dust and pollute the surrounding air and environment.
  • 10. What kind of ceramic media is the best quality?
  • If you don’t know where to find the best ceramic media, here are some tips to help you decide:

    10.1 The shape of the ceramic media. The forming process in the production process of ceramic media is a link that reflects the manufacturing process level of the manufacturer. Good quality control capabilities determine that the ceramic media’s mixing, mud refining, shaping, cutting, and sintering processes all have qualified quality control capabilities. The ceramic media produced in this way have uniform shapes, consistent sizes, smooth surfaces, and sharp corners, these performance indicators ensure that cracks, mud occur rarely.

    10.2 The hardness of the ceramic media. This indicator reflects the sintering temperature control level of the kiln. If the kiln temperature is too low, the melting reaction of various micro-powders inside the ceramic media is insufficient, the tumbling media is too tender, the hardness is not up to standard, and the wear is very high during use. If the kiln temperature is too high, it will cause over-burning. Corundum sand on the surface of the ceramic media will precipitate, resulting in a porridge-like surface and the product will be scrapped.

    10.3 Durablity of ceramic media. Excellent product raw material quality, strict production process control, and just the right formula combination can produce high-quality ceramic media. The wear resistance of ShineTec’s tumbling media can reach about 3 times that of other manufacturers on the market. You can compare the use cost, which can reduce the direct cost of your product finishing and polishing process by 3 times.

  • 11. How to choose a suitable ceramic media?
  • 11.1 Choose the material of your ceramic media based on the effect you want to achieve. If you want to deburr, descale, deflash, derust, chamfer and other finishing effects on your product parts, then you should choose ceramic deburring media, silicon carbide deburring media, white Corundum finishing media and chrome corundum finishing media are abrasives with cutting force. If you just want to improve the surface brightness of your product, you need to choose polishing porcelain media, high-density porcelain media, and zirconia polishing bead, which are non-cutting and high-density tumbling ceramic media. If your product is made of soft metals such as aluminum alloy, copper, and zinc, you need to choose a resin media.

    11.2 Choose the appropriate ceramic media based on the size and surface condition of your product. If your product does not have holes, or cracks, then choose a larger deburring media so that it has a long service life and will not produce stuck holes or clogging even after its shape becomes smaller.

    11.3 Choose the appropriate ceramic media based on surface roughness. For rough products, choose a tumbling media with strong cutting force and sharp product corners. For precision parts, choose a abrasive media with fine abrasive grit and low cutting force.

About Finishing Media

  • 1. What is the finishing media?
  • All materials that are naturally produced or artificially produced and have high hardness, cutting ability and certain strength and toughness, and are used for grinding, finishing or polishing, can be finishing media, abrasive media. Finishing media are a diverse category, and many people have questions of one kind or another, such as: What are finishing media? What are the commonly used finishing media? What are finishing media used for? What are the types of finishing media? Let’s talk about these issues in detail below.
    natural abrasives
  • 2. What are the types and uses of commonly used finishing media?
  • According to the source, abrasives can be divided into two categories: natural abrasive media and artificial finishing media.

    2.1 Natural abrasive media include diamond, natural corundum (also called emery), garnet, quartz sand, diatomaceous earth, pumice, flint, silica, feldspar, chalk, lime for polishing, etc.

    2.1.1 Diamond. Diamond is the hardest substance currently known. The main ingredient is carbon, which is expensive because of its limited origin. Mainly used for manufacturing resin, ceramic or metal bonded abrasive tools. Diamond has a sharp shape and is the best abrasive tool for grinding hard and brittle materials such as cemented carbide, optical glass, and ceramics. It has a better polishing effect on alloys of different phases with huge differences in soft and hard. In addition, diamond polishing abrasive media have the characteristics of long finishing life, high cutting ability, and strong wear resistance. However, because it is easily carbonized at 700℃~800℃, it is not suitable for finishing steel materials and ultra-high-speed grinding.

    2.1.2 The main components of emery are aluminum oxide (Al2O3), a small amount of iron oxide (Fe2O3) and other impurities. It can be used for finishing and polishing all metals.

    2.1.3 Garnet is the oldest type of polishing abrasive media. It was called Ziyawu in ancient China. It has been used to grind gemstones since the Bronze Age. It gets its name because the crystal particles are shaped like pomegranate seeds. It is mostly used for sandblasting, waterjet cutting, manufacturing coated abrasive tools, filter materials, wear-resistant floor aggregates, etc. It is used in hardware, steel, castings, ceramics, aluminum, wood, and leather industries.

    2.1.4 The main component of quartz sand is SiO2, which is the earliest grinding wheel material and can be used for grinding, polishing, tumbling and sandblasting. The main component of diatomite is also SiO2, which is an ingredient in the manufacture of polishing powder and whetstone. Suitable for finishing and polishing soft metals such as brass, aluminum, and zinc.

    2.1.5 Pumice comes from volcanoes and is the raw material for making polishing powder. Suitable for finishing and polishing soft metals and their alloys, wood, glass, plastic, leather, etc.

    2.1.6 Flint, is a relatively common siliceous rock. Because flint is hard and produces sharp fractures when broken, it was first favored by primitive people in the Stone Age and used to strike and make stone tools. The striking of flint and iron tools will produce sparks, so it was also used as a fire-making tool by ancient people. In ancient China, a small piece of flint and a steel “fire sickle” were often struck to make fire, so flint is also called flint. The modern grinding industry utilizes its hard and sharp edges as grinding materials.

    2.1.7 Silica is the general name for vein quartz, quartzite, and quartz sandstone. The main component is also SiO2. Silica has a wide range of uses. When used in the grinding industry, it can be used to make grinding stones, oil stones, and sandpaper. It can also be used to polish glass, Surface of metal products, sawing and grinding stones, polishing jewelry, etc.

    2.1.8 Feldspar is the general name for feldspar minerals. There are many types, such as albite, anorthite, barium feldspar, barium adolite, microcline feldspar, orthoclase, feldspar, etc. The main component is feldspar. Silicon oxide, aluminum oxide, K2O, sodium oxide, calcium oxide, etc. When used in the grinding industry, it is often used as a bond component in the production of bonded abrasive tools, such as grinding wheels.

    2.1.9 Chalk is calcium carbonate and has a wide range of uses. It is used in the grinding industry as a raw material for tooth powder, toothpaste and other cosmetics.


    2.2 Artificial abrasive media. It is an abrasive material that does not exist in nature and is entirely artificially produced. The main types are:

    2.2.1 Sintered abrasives. Mainly divided into corundum abrasive media, silicon carbide abrasive media and CBN (cubic boron nitride) abrasive media, the varieties are divided into:

    Brown corundum abrasive media. The main component is Al2O3, which has medium hardness, high toughness, sharp particles, relatively low price, and is suitable for processing metals with high tensile strength.

    White corundum abrasive media. Its hardness is slightly higher than brown corundum, but its toughness is poor. It is easy to cut into the workpiece during finishing. It has good self-sharpening, low heat generation, strong finishing ability and high efficiency. Chrome corundum abrasive media is its derivative.

    Single crystal corundum abrasive media. Its particles are composed of a single crystal and have good multi-edge cutting edges, high hardness and toughness, strong grinding ability, and low grinding heat. The disadvantage is that the production cost is high and the output is low, so the price is relatively high.

    Silicon carbide abrasive media. Divided into black silicon carbide abrasives, green silicon carbide abrasives, cubic silicon carbide abrasives, and cerium silicon carbide abrasives. The main component is SiC, which has high hardness, high brittleness, sharp abrasive grains, good thermal conductivity, and strong wear resistance. It is more suitable for processing hard and brittle metal and non-metallic products. At present, the finishing and cutting of most NdFeB magnetic materials is widely used.

    CBN (cubic boron nitride) abrasive media. It is a synthetic super-hard material, its hardness is second only to diamond, and it is an excellent grinding material. Compared with traditional grinding materials, CBN abrasives have excellent grinding performance, especially when grinding cemented carbide, and are more efficient. CBN abrasive media are known as one of the greatest technological advances in the history of the abrasives industry due to their high strength, high wear resistance, excellent hardness close to diamond, and excellent thermal stability. The wear resistance and hardness are more than four times that of traditional abrasives, and its unique chemical properties also make it particularly suitable for grinding ferrous metal materials.
    The thermal integrity of CBN abrasive media and their ability to maintain a sharp cutting edge when machining ferrous materials makes them the product of choice for advanced grinding systems. When grinding ferrous metals, they do not react with each other; when grinding steel alloys, they are not easily oxidized. This makes CBN abrasive media the first choice for high-performance grinding wheels for grinding different materials such as cast iron and hard steel.
    CBN abrasive media can withstand high temperatures of 1300℃~1400℃, are chemically inert to iron group elements, have good thermal conductivity, have high removal rates when grinding steel, have large grinding ratios, and have long tool life. They are ideal for grinding hardened steel, The best abrasive for metals with high hardness and toughness such as high-speed steel, high-strength steel, stainless steel and heat-resistant alloys. In addition, CBN abrasive tools are also suitable for ultra-high-speed grinding, and metal-based CBN abrasive tools will not break even if the linear speed exceeds 250m/s.


    2.2.2 Preformed finishing media.
    There are two types of such finishing media: One is sintered ceramic media; also known as ceramic deburring or polishing media. Corundum sand or silicon carbide powder, quartz powder, alumina and other materials are melted at a high temperature of more than 1,000 degrees and sintered into a finishing media with very high hardness. The other is abrasives media bonded with resin, called resin media, polyester media or plastic media. This type of abrasives media can be made into triangular, spherical, square, conical, cylindrical and other shapes. Each shape of abrasives media has different sizes.


    2.2.3 Steel finishing media.
    It can be made into hard steel balls, stainless steel balls, ballcone, ufo, needles, pins, angle cut cylinder and other shapes. This type of abrasive media has high strength and is not easily broken. It is mainly used for polishing surface brightness.


    2.2.4 Bio-degradable finishing media.
    Commonly used ones include corn cobs, walnut shells, sawdust, shredded felt, shredded leather, etc. It is mainly used in the tumble polishing process. It is used for the final polishing and drying of parts that have been treated with light finishes, and can achieve an effect close to mirror polishing.

  • 3. What is tumbling finishing media?
  • Tumbling finishing mediaalso called tumbling abrasive media and mass finishing media, refer to abrasive media that use tumbling, vibrating, rotating and other motion methods to finishing the surfaces of product parts and workpieces. It can be natural abrasive media such as river sand, stones, and plants, but most of them use artificial abrasives, including abrasive media with cutting force and polishing media without cutting force. This artificial abrasive media comes in a variety of shapes, including tri-angle, ellipses, spheres, cylinders, tri-star shapes and other clumps, so it is also commonly called tumbling media. It can be said that tumbling abrasive media are one category of abrasive media, but because natural abrasive media are rarely used now, tumbling media actually refer to tumbling abrasive media in most cases.

  • 4. What can tumbling finishing media be used for?
  • Tumbling media can deburr, descale, deflash, chamfer, derust, degrease, clean, polish, brighten on metal and non-metallic parts and workpieces. The advantage of this kind of finishing media is that it can quickly finish products in large quantities, automatically, and has the characteristics of low cost, high efficiency, safety and environmental protection.
  • 5. What are the types of tumbling finishing media?
  • Tumbling media are divided into three types of abrasive media: rough finishing, fine finishing and polishing:

    5.1 Rough finishing media, mainly includes brown corundum ceramic media, resin ( plastic) media, divided into heavy cutting force, medium cutting force and light cutting force.

    5.2 Fine finishing media, includes white corundum ceramic media, chrome corundum ceramic media, 3P abrasive media, etc. Because the grit size of the micropowder contained in it is very fine, some of which are nearly 2000-3000 mesh, it can continuously perform micro-cutting on the surface of the workpiece to form a more delicate surface roughness, which is suitable for finishing and polishing precision parts.

    5.3 Polishing abrasive media include high-alumina porcelain media, high-density porcelain media (high-alumina porcelain media with an alumina content of more than 95%), stainless steel media, walnut shell abrasive media, corn cob abrasive media, etc. The main purpose is to improve the gloss and brightness of the workpiece surface.

  • 6. How does tumbling finishing media work?
  • The shapes of tumbling finishing media include triangles, spheres, cubes, cylinders, three-star shapes, etc. The cutting surfaces are straight and angle to form acute angles at different angles. The specifications are also available in dozens of sizes from 1mm to 60mm, which are suitable for each. Finishing and polishing of internal and external surfaces of product parts with irregular and complex shapes, holes, seams, corners and other parts. The main mode of operation is to put the abrasive media and parts together into the working barrel of the tumbling finishing and polishing machine, and use the vibrating, tumbling, rotating and other mechanical movements generated by the machine to cause the abrasives to rub and cut on the surface of the workpiece to achieve the effect of finishing and polishing.

  • 7. How to choose the correct tumbling finishing media?
  • There are several factors to consider when purchasing tumbling media:

    7.1 Cutting force. This indicator determines the speed at which the workpiece is ground. Heavy-cutting abrasive media can finish parts faster but produce a relatively rough surface finish. Conversely, light-cutting abrasive media finish more slowly but produce higher surface quality.

    7.2 Durability. Wear resistance determines the service life of abrasive media. Wear resistance is affected by factors such as the quality of various raw materials, the particle size and content of abrasives, the matching degree of binder and corundum sand, the condition of vacuum during molding, and the control of sintering temperature. This is a key indicator reflecting the quality of abrasives.

    7.3 Hardness. Workpieces with different hardnesses require tumbling media with different hardnesses for finishing. The harder the workpiece, the harder the abrasive media is required to polish it. If high-hardness abrasives are used to polish workpieces made of soft materials, they may cause damage to the workpiece. For example, if aluminum alloy workpieces are ground with brown corundum ceramic deburring media, the surface will be dull, corrosion pits (impacting points) and a deformation disturbing layer will be produced on the surface.

    7.4 Shape and size. Different shapes and sizes of product parts require matching abrasive media of different sizes and shapes. Generally speaking, the larger your workpiece is, the larger the media will be, and the smaller the workpiece will be, the smaller the abrasive will be. Particular attention should be paid to the shape and size of the abrasive media so that it cannot get stuck in the inner holes, pipes, gaps, corners, etc. of your product.

  • 8. What is the best tumbling finishing media?
  • To measure the quality of finishing media, the most critical factors are cutting efficiency and wear resistance. However, in terms of production and manufacturing processes, these two are contradictory indicators. To achieve high cutting efficiency, you need to use large-grained corundum sand. However, the larger the particle size of the sand, the easier it is to fall off from the matrix during finishing, affecting the wear resistance of the abrasive and causing high wear. Here it is necessary to master the bonding strength between the sand grains and the binder, find a balance point, and maximize the cutting force of corundum sand while enhancing the bonding strength with the matrix. It requires both high cutting force and strong wear resistance. This is the core technology that produces the best tumbling media.

  • 9. How long is the service life of tumbling finishing media?
  • The service life of tumbler media typically ranges from several months to several years, depending on the hardness, shape, and size of the workpiece being ground. Workpieces with sharp burrs and edges, sharp edges, flash edges, higher hardness and larger appearance will cause greater loss to the abrasive. The service life is shorter.
    Of course the most basic factor depends on the quality of the tumbler media. Good abrasive media will enhance wear resistance while ensuring grinding efficiency. ShineTec’s tumbler media are mature and stable formulas formed on the basis of dozens of process formula tests. Corundum sand has the best material match with other binders, and the wear resistance of the products is longer than other products on the market in terms of service life. There is a 3 times improvement.
  • 10. How to calculate the volume matching ratio between finishing media and workpiece?
  • What is the most appropriate loading ratio of tumbler media to workpiece during primary finishing and polishing? This ratio depends on the finishing effect you want to achieve. Factors that need to be considered include the material, size, shape of the abrasive media, the material and weight of the workpiece.
    Below is a basic tumbler media : parts ratio guide, please refer to the table below to determine your usage:

    Tumbler Media to Workpiece Volume Ratio Typical Application
    0 : 1 no abrasive media, and the product is self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 Same proportion of tumbler media and products with very rough surface, such as forgings, castings, etc.
    2 : 1 Light finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for finishing and polishing ferrous metals.
    4 : 1 Average efficiency ratio of non-ferrous metal workpieces. High efficiency ratio for ferrous metal parts.
    5 : 1 Suitable for finishing and polishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing and polishing of non-ferrous metal products. It is often used for pre-plating treatment of resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing and polishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better polishing quality. Suitable for irregular shapes or fragile workpieces.
    Max No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.
What is the automatic mass finishing system?

About Automatic Mass Finishing System

  • 1. What is the automatic mass finishing system?
  • The automatic mass finishing system, also called the automatic finishing and polishing production line, is a mechanical equipment for finishing and polishing that uses modern transmission and electrical control technology from a series of processes such as feeding, deburring, polishing, cleaning, separating, drying, and discharging, combined into a complete set of integrated assembly lines. The main purpose is to reduce manual work, improve production efficiency, reduce production costs, and ensure the surface treatment quality of product workpieces.
  • 2. Why do I need to use the automatic mass finishing system?
  • For some manufacturers who need to carry out a large amount of daily finishing and polishing treatments such as deburring, descaling, deflashing, derusting degreasing, cleaning, polishing and brightening, etc., they are generally equipped with multiple finishing and polishing machines and Complete with auxiliary equipment. For example, some machines are used for rough finishing, some machines are used for fine finishing, and some machines are used for polishing brightness. The flow of product workpieces between different machines requires loading, unloading, and screening, cleaning, transportation, drying and other different processes, each process requires personnel to operate. Medium and large operating capacitibility of mass finishing machines usually process hundreds or even thousands of kilograms every time. The labor intensity of loading and unloading so many parts into different machines is huge. Moreover, manual loading and unloading takes at least half an hour at a time. Therefore, using independent machines to perform polishing operations is a time-consuming and laborious task that requires a lot of labor costs and has low production efficiency.

    In order to reduce labor intensity and improve work efficiency, we can design and connect the finishing and polishing machines at different process points using auxiliary facilities such as mechanical hydraulic lifting, conveying transmission, online cleaning, and online separating, so that the product workpiece can be completely processed from feeding to finished product discharging. Realize online operation, reduce manual intervention, and realize automated mass finishing functions.
    Using these modern mechanical and electrical control technologies, you can turn your mass finishing equipment into a fully automatic CNC finishing machine, greatly improving equipment utilization, reducing labor costs, increasing finishing and polishing efficiency, and creating greater profits for your factory. If you don’t know where to find this kind of automated mass finishing system, we can analyze the calculation data and propose a solution based on your actual production situation.

  • 3. What systems does the automatic automatic mass finishing system consist of?
  • 3.1 Automatic loading system. The first machine that starts the finishing process will be equipped with a material lifting hopper. Workers only need to put the abrasive media or product workpieces before rough finishing into the hopper and control the lifting of the hopper to put the materials into the machine.

    3.2 Tumbling finishing and polishing machines. The finishing machine is the main component of the automatic finishing and polishing production line. This part of the system can be vibratory finishing machine, or centrifugal disc finishing machine, or centrifugal barrl finishing machine, even Rotary tumbling barrel finishing machine.

    3.3 Auxiliary discharging device. Every finishing machine needs to unload after finishing is completed. When the vibrating finishing machine discharges materials, it is necessary to configure a hydraulic or pneumatic turning plate inside the machine to connect the bottom of the machine’s working chamber and the discharge port separating screen. When the material needs to be discharged, press the control button to turn the flap up and close the separating screen, so that the workpiece can automatically climb from the groove to the separating screen and output the workpiece. When the centrifugal disc finishing machine discharges materials, it is necessary to use the hydraulic struts at the bottom of the barrel of the machine to hold up the barrel and turn it over, so that the abrasive media and the workpiece can be poured into the built-in vibrating separator for discharge. Centrifugal barrel finishing machines are rarely integrated into automatic production lines. There is no need to equip additional special equipment when discharging materials. You only need to turn the barrel opening downwards to pour out the materials.

    3.4 Separating device. Each machine is equipped with a separating screen to automatically separate workpieces and abrasives after discharging. The vibrating polishing machine is built into the working bowl, and the other three machines require additional special separating screens.

    3.5 Transmission system. Using mesh belts and rollers, the separated workpieces are transferred to the machine for the next process. Some transfer systems are also equipped with a flushing function to clean the workpiece again during the transfer process.

    3.6 Water-liquid circulation system. Using the sewage treatment system, the flushed wastewater containing polishing compound is recycled and filtered and pumped into the machine again for use.

    3.7 Drying system. There are two ways, one is to transport the cleaned workpieces into a vibrating dryer, the other is to equip an online pass-through drying box to dry the workpieces on the conveyor belt.

  • 4. What types of automatic automatic mass finishing system does ShineTec have?
  • According to different finishing machines, there are four types of automatic mass finishing system: vibratory finishing system, centrifugal disc finishing system, centrifugal barrel finishing system, and barrel tumbling finishing system. The first two models are most commonly integrated into production lines.
  • 5. Where can the automatic mass finishing system be used?
  • All factories that currently need to use multiple finishing machines for surface treatment processes such as deburring and descaling can consider configuring automated mass finishing system.
    Here are some questions you can pre-evaluate:

    How do your product workpieces flow between polishing machines in different processes?

    How long does it take to transfer between each different process?

    How did you add water and polish compound?

    How do you separate tumbling media and workpieces?

    If an automatic assembly line is used for circulation, how many finishing batches can be added?

    On this basis, after comparing the investment returns, you can consider whether to invest in this kind of automated mass finishing production line.

  • 6. How to choose a suitable automatic mass finishing system?
  • It is indeed a challenge to choose an automated mass finishing system that is most suitable for your product finishing and polishing process.

    The tumbling barrel finishing automated production line is the slowest type of work efficiency, but it can achieve the most beautiful results for the surface polish quality of the product, especially for surface finish and gloss. In terms of brightness, it can have an effect close to mirror polishing.

    Automatic vibratory (vibrating) finishing system are the most widely used type. Its working efficiency is much higher than that of the barrel finishing type. Because of the built-in separating screen, the material can be discharged directly from the working chamber, and there is no need to add a hydraulic lifting device to flip the working barrel. Therefore, the manufacturing cost of the entire production line can be lower than that of the disc finishing type and centrifugal barrel finishing type.

    Automatic centrifugal disc finishing system are also widely used. It has the highest working efficiency and can quickly achieve finishing and polishing effects. Since this type of machine needs to use a hydraulic lifting device to pour the materials in the barrel into a separately configured screen when discharging materials, the overall cost of the assembly line is higher.

    Automatic centrifugal barrel finishing system is suitable for surface treatment of precision parts. Because the processing capacity is small, it is not necessary to integrate into the assembly line, so there are few application areas.
    If you don’t know which type of mass finishing system your product is suitable for, please contact us. ShineTec will conduct professional evaluation analysis and calculations for you and provide you with the most cost-effective solution.

    8.1 Tumbling media for rough finishing, mainly include ceramic deburring media, Resin media , divided into heavy cutting force, medium cutting force and light cutting force.

    8.2 Tumbling media for fine finishing, white Corundum finishing media, chrome corundum finishing media, 3P finishing media, etc., because the particle size of the micropowder contained in it is very fine, some of which are nearly 2000-3000 mesh, it can continuously perform micro-cutting on the surface of the workpiece to form a more delicate surface roughness.

    8.3 Tumbling media for polishing, include porcelain media, high-density porcelain media (a high-alumina porcelain media with an alumina content of more than 95%), stainless steel media, walnut shell polishing media, corn cob polishing media and so on. The main purpose is to improve the gloss and brightness of the workpiece surface.

    If you don’t know which is the best polishing media, please contact us and ShineTec can provide you with professional suggestions and answers.

  • 9. How long does it take to complete the polishing process on the automatic mass finishing system?
  • Now, the time it takes to polish a batch of workpieces using an automatic mass finishing system is definitely much shorter than manually operating several independent finishing machines.

    The length of processing time depends on which type of production line you have applied. Generally speaking, the centrifugal disc type and barrel type can complete the grinding work within 30 minutes. With discharging, cleaning and other processes, the entire process can be completed in as fast as 1 hour from feeding to discharging. The vibration-type unit may take 2 hours to complete the entire process, while the tumbling barrel-type unit may take longer and may take several hours to complete the finishing work.

  • 10. What is the daily maintenance of the automatic mass finishing system?
  • Regular daily maintenance can keep your polishing automatic production line in the best working condition, extend the service life of the machine, and reduce maintenance expenses.

    10.1 Inspection of mechanical components. The vibrating finishing automatic production line needs to add lubricating grease to the vibration motor used in the machine every month; the disc automatic finishing production line needs to check whether the gap between the barrel and the chassis is normal, whether there is a chuck, and whether the transmission belt is Relaxation; for a centrifugal barrel automatic polishing production line, it is necessary to check whether the transmission chain, sprocket or timing belt is worn, whether there is any abnormal noise during operation, and whether the barrel cover can be sealed; for a tumbling barrel-type automatic polishing production line, it is also necessary to check whether the transmission part is working Normal, there is no leakage after the cover is sealed. Some pneumatic or hydraulic devices on the production line also need to be checked for air and liquid leaks.

    10.2 Check the loading of abrasive media used. The loading of abrasive media in the machine should be checked before each start-up. Too much or too little usage will cause damage to the machine or product workpiece, affecting the efficiency of finishing and polishing.

    10.3 Water circulation system inspection. Check whether the water inlet, drainage, and quantitative filling of polishing compound are working properly. Pay special attention to whether the drainage pipe of the machine is blocked.

    10.4 PU lining examination. Check whether the PU or rubber lining of the machine is worn or damaged. If so, it needs to be replaced immediately.

    10.5 Don’t overdo it. Do not overload abrasive media and product workpieces into the machine. Generally, the total volume of materials does not exceed 70% of the total capacity of the machine. If stainless steel media need to be used in the machine, due to their large proportion, they are generally controlled within 50%.

    ShineTec's automatic wastewater treatment system
  • 2. Why is wastewater treatment needed?
  • The finishing process of deburring and descaling requires the use of various abrasive media and Chemical Finishing Compound. Most abrasive media such as ceramic media, high alumina porcelain media, resin media and other materials will produce a large amount of sludge due to wear during the grinding process. This sludge is mixed with metal debris and other impurities that fall off the workpiece due to wear and tear. If not cleaned in time, the surface of the product will be worn. Therefore, during the finishing and polishing process, it is necessary to flush with water from time to time, and then flush with clean water. The waste water discharged from the drain outlet of tumbling finishing machine must be treated Environmentally friendly treatment and discharge directly.
    In addition, a large amount of clean water is used during the finishing process, and it is also mixed with chemical additives such as polishing compound. For environmental reasons, you cannot discharge this wastewater directly into the surrounding environment.
    This automatic sewage treatment system can solidify and dry sludge, recycle wastewater, and meet environmental protection requirements. It can well solve the problem of not knowing how to treat wastewater.

  • 3. Can the water treated by the automatic wastewater treatment system be reused?
  • Yes, the water treated by the automatic sewage treatment machine can be reused in the tumbling finishing machine.
  • 4. How does the automatic wastewater treatment system treat the sludge and sewage generated after finishing and polishing?
  • The wastewater discharged after finishing and polishing is introduced into the wastewater treatment tank of the automatic sewage treatment machine, which is also called a coagulation sedimentation tank. By adding some treatment agents to the water, usually called coagulants or coagulants, the particles that are difficult to settle in the water can aggregate with each other to form colloids, and then combine with other impurities in the water to form larger flocs. The large organic particles in the polishing liquid are adsorbed by the flocs, increase in volume and sink. The well-reacted wastewater is pumped into the filter press system for solid-liquid separation, forming mud cakes for solid waste treatment. The filtered water has been discharged up to standard and can be used for secondary use.

About Hardware Tumbler

  • 1．What is hardware tumbler?
  • ShineTec’s hardware tumbler is a kind of automatic hardware finishing machinery and equipment, specially used for machining, precision molds, auto parts, aerospace, medical equipment, mechanical parts, plastic products, 3C digital, metal casting, electronics High-efficiency high-volume deburring, deflashing, descaling, smoothing, polishing of hardware parts produced in devices, hardware parts, kitchen supplies, 3D printing, textile workpieces, powder metallurgy, electrical components, minting, jewelry, instrumentation, handicraft accessories and other industries.
    ShineTec's hardware finishing and polishing machine
  • 2. Why use a hardware tumbler for finishing and polishing?
  • I believe that as a manufacturing owner, your products will no longer want to use manual polishing methods. If your products are still polished manually, we recommend that you try ShineTec’s automatic hardware finishing machine. The specific advantages are as follows:

    2.1 Compared with manual deburring, the efficiency can be improved dozens of times. Using some large-scale deburring and polishing machines, hundreds or even thousands of kilograms of material can be fed at one time, and all can be completed within dozens of minutes or hours. This processing efficiency is incomparable to manual polishing.

    2.2 The surface effect after polishing is uniform and controllable. The quality of hand polishing depends on the personal skill proficiency of the worker. Some products may have burrs finished cleanly, while others may still have some residue. The surface quality of each product is different. Sometimes it may also cause product damage, resulting in a relatively high scrap rate.

    2.3 The operating costs of a automatic hardware tumbler are extremely low. The one-time purchase cost of the machine starts from a few thousand dollars, and it can generally be used for many years. The choice of ordinary polishing materials depends on the actual situation of the product parts that need to be processed, and the price ranges from a few dollars per kilogram to more than ten dollars. , buying a few hundred kilograms at a time can usually take several months. The amount of polishing compound is very small and the cost is almost negligible.
    Ordinary models can feed dozens of kilograms of workpieces at a time, and the finishing time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.

    On the other hand, the advantages of automated hardware tumbler are even greater in terms of saving labor costs. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

    2.4 In addition to the automatic deburring function, ShineTec’s hardware tumbler can also perform surface polishing processes such as descaling, derusting, deflashing, cleaning, chamfering, degreasing, decontaminating, and improvement of surface brightness. Craftsmanship, powerful functions and wide applicability.

  • 3． What kind of polishing effect can the hardware tumbler achieve?
  • In terms of polishing efficiency, this fully automatic hardware tumbler can process hundreds or thousands of kilograms of mechanical parts and hardware components at a time. It is a kind of automatic hardware polishing mechanical equipment that has been widely used.

    The effect of finishing depends on your needs for the product surface. To achieve the best surface finishing and polishing effect, most product polishing processes require three processes: rough finishing, fine finishing, and polishing.

    The first step is to finish it roughly. Use abrasive tumbler media with high cutting force to remove defects such as burrs, scale, flash, sharp edges on the product surface to form a smooth surface with low surface roughness.

    The second step is fine finishing. Use abrasive tumbler media with finer grit, some reaching micron powder size, to further perform micro-cutting on the product surface to achieve a smoother surface quality.

    The third step is polishing. Use high-density, non-cutting polishing tumbler media, such as high-aluminum porcelain media, high-density porcelain media, stainless steel media, or some bio-degradable tumbler media that can simulate the polishing effect of cloth wheels, such as walnut shell abrasive chip, corncob abrasive chip, polishing Wood particles, etc., combined with special brightening compound, can improve the gloss and brightness of the product surface and achieve a sparkling, close to mirror polishing effect.

  • 4. Are there any defects to hardware tumbler?
  • The main disadvantage of this automatic hardware tumbler is that it cannot polish a certain part of the product surface because it is an overall polishing process. For example, the oxide scale on the surface of a certain part of a product is relatively thick. If you want to focus on this part and spend more time to finish it, this will not work. The thickness of this part is ground, and other parts will also be ground to such a thickness.

    The surface quality is not as good as mirror polishing.

    Some inner holes and cross holes that are too deep and too thin, such as inner surfaces exceeding 50mm, cannot be finished and polished.

    Too long burrs and flash edges cannot be processed. For example, burrs and flash edges exceeding 2mm.

  • 5. How does the hardware tumbler finish and polish?
  • In order to solve the problems of low efficiency, low quality and high labor cost of manual finishing, ShineTec’s Hardware Tumbler is an automatic finishing and polishing machine. The main operating principle is to mix special tumbler abrasive media with product workpieces, appropriate amounts of water and finishing liquid in a certain proportion, and put them into the working barrel of the polishing machine, and use mechanical motion methods such as vibration, centrifugal high-speed rotation, tumbling rotation, etc. to make the ceramic tumbler media and workpiece tumble and rotate together in the barrel, and use the cutting force of the abrasive surface to finish the burrs on the surface of the workpiece.

    There are four main types of deburring and polishing machines. Each movement mode has its own advantages and disadvantages, and is suitable for different finishing and polishing needs. Vibratory finishing and polishing is the most common process method. If you need to process large quantities every day, such as hundreds of kilograms of product workpieces, then choose a vibrating polishing machine. If you need to process some small precision parts and components, the quantity is within tens of kilograms, Precision parts finishing and polishing machine is the best choice, then the centrifugal barrel finishing process is the most suitable method. If you are looking for the fastest polishing process, then centrifugal disc finishing is the fastest polishing method. If you want to find the cheapest, lowest cost finishing and polishing process, go for the tumbling barrel finishing method.

  • 12.1 Before each start-up, should the overall appearance of the machine be checked for damage? Is the foot position stable? Is there any abnormal noise during operation?

    12.2 Depending on the model, do you regularly check whether the spring of the machine is broken? Are there any cracks in the casing? Does the tension of the transmission chain, synchronous belt, and sprocket match? Is the lining damaged? Is there any water leakage from the sealing cover?

    12.3 The motor needs to be lubricated every month. Are there any signs of aging and failure of the electrical components? Is the copper wire of the electric wire exposed?

    12.4 Operate within the rated load capacity of the machine and do not overload it. Generally, the material loading capacity of the entire machine should not exceed 70% of the total load capacity of the machine.

    If you are a hardware finishing job shop, your finishing and polishing equipment must be in working condition for a long time, so good maintenance habits can better extend the service life of your hardware tumbler and create more benefits for you.

  • 13． How to buy a hardware tumbler?
  • As a finishing and polishing machine manufacturer, we have a variety of mass finishing machines available. Before ordering, you need to send samples for process testing. If you are satisfied with the results, please refer to the following steps to confirm your ordering requirements:

    13.1 Power requirements. Our hardware tumbler requires 380V/3-phase/50Hz industrial power and is not suitable for civilian 220V/2-phase power. Special requests need to be confirmed in advance.

    13.2 Processing capability requirements. First estimate the quantity of your product that needs to be processed every day, your shift schedule, and confirm the machine model based on the process plan.

    13.3 Your product parts size. These workpieces within 300mm can all be processed, but the vibrating finishing machine is the most commonly finisher. For workpieces that are too long, a long rectangular tub finishing machine is needed. Some small-sized precision parts require a precision finishing machine. It is recommended to use a centrifugal barrel finishing machine. Workpieces within 100mm require rapid deburring and polishing, then the centrifugal disc finishing machine is the best choice, It is not afraid of deformation or bumping. For thin workpieces within 300mm in length, which are easy to adsorb each other, use a barrel tumbling finishing machine.

    13.4 Selection of tumbling media. According to the effect of the testing sample, select the appropriate abrasive material, cutting strength, shape, and size.

    13.5 Wear resistance of tumbling media. Different cutting strengths, shapes, and sizes determine the different wear resistance properties of abrasive media. Finishing media with heavy cutting force have smaller wear resistance than media with light cutting force due to the large grit size of corundum sand contained. The larger the product, the longer it will last and the more wear-resistant it will be. There are also different shapes with different wear resistance. For example, shapes such as spheres and cylinders are more durable than triangles and tri-star shapes.

    13.6 Finishing time. The finishing efficiency of each model is different. You should choose the appropriate model based on your production shift schedule, product output, and batch processing time requirements for deburring and polishing.

    13.7 The intensity of working. The bowl of the vibrating finishing machine is open, making it easy to load materials; the disc type is similar and easy to load and unload; the centrifugal barrel type has a smaller working barrel and a smaller opening, so it takes more time to load and unload. The opening of the tumbling barrel is also small, and the loading and unloading of materials is relatively slow; the overall labor intensity and loading and unloading time are stronger than the disc type, the tumbling barrel type, and the centrifugal barrel type.

  • 14. How to improve the polishing efficiency of hardware tumbler?
  • Some precautions during actual use can help improve the efficiency of the hardware tumbler.

    14.1 Reasonable ratio of abrasive media to workpiece. The reasonable ratio of the two when loading and feeding is the key factor affecting the finishing and polishing efficiency. The most commonly used ratio is 3:1 abrasive media to workpiece. Please refer to the table below to determine your usage:

    Media to workpiece volume ratio Typical application
    0 : 1 No tumbling media, self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 The same proportion of abrasive media and parts such as forgings, castings, etc., with very rough surfaces.
    2 : 1 Gentle finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for finishing copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for grinding and polishing ferrous metals.
    4 : 1 The ratio of non-ferrous metal workpieces with average efficiency. High polishing efficiency ratio for ferrous metal parts.
    5 : 1 More suitable for finishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing of non-ferrous metal products. Commonly used for pre-plating treatment with resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better finishing quality. Suitable for irregular shapes or fragile workpieces.
    Maximizing No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.


    14.2 Loading capacity. Too much or too little loading will affect the finishing efficiency of the machine. Please do not feed materials at 100% full load or less than 50%. Generally, the overall volume of the material after loading does not exceed 70% of the barrel volume, and the water surface does not exceed 80% of the barrel volume.

    14.3 Amount of finishing compound liquid. Too little dosage will definitely not play the role of the additive in accelerating grinding. Too much dosage will produce a large amount of foam, which will pollute the environment, and on the other hand, it will block the tumbling and rotating motion of the abrasive media and the workpiece, reducing the grinding efficiency.

    14.4 Suitable machine operating speed. This is a process that requires long-term experience accumulation. Polishing efficiency depends on the material and size of the tumbling media used, the amount of water and chemical compound added, and the running speed of the machine. Too little material input and high-speed machine operation speed will cause over-grinding of the product, affecting the overall size, accuracy or chamfering degree. Excessive material input and too low machine speed will cause insufficient movement of the workpiece inside the abrasive media, reduce cutting strength, and affect efficiency.

  • 15. How long does it take to polish the parts with a hardware tumbler?
  • There are three factors that determine the finishing time it takes to a hardware deburring tumbler:

    15.1 The material and surface condition of the workpiece. The length, thickness, and location of burrs, flash, and sharp edges will all affect the processing time. In addition, the harder the workpiece is, the longer it will take. On the contrary, the softer the workpiece will be, the shorter the time will be.

    15.2 The choicing of polishing machines. Generally speaking, compared by finishing speed, centrifugal disc finisher > centrifugal barrel finisher > vibratory finisher > tumbling barrel finisher.

    15.3 The capacity of the machine. The larger the capacity of the machine, the greater the friction process between the abrasive media and the workpiece, and the faster the desired effect can be achieved.

  • 16. Which hardware tumbler is the best?
  • In the surface treatment industry, there are various finishing equipment and polishing process methods. Such as manual polishing, robot polishing, chemical polishing, electrolytic polishing, abrasive flow polishing, magnetic polishing, sandblasting and shot blasting, plasma polishing and other processes. Each polishing method has its own characteristics and applicable fields, so no one polishing machine is the best. Only the equipment that is more suitable for your own product polishing needs is the best.

  • 2. What are the advantages of a parts deburring machine compared to manual deburring?
  • In an era of automation and intelligence, are you still looking for manual deburring methods? Let us recommend to you this large-volume, high-efficiency automatic deburring and polishing process. Its comparative advantages over manual deburring are as follows:

    2.1 Compared with manual deburring, the efficiency can be improved dozens of times. Using some large-scale deburring and polishing machines, hundreds or even thousands of kilograms of material can be fed at one time, and all can be completed within dozens of minutes or hours. This processing efficiency is incomparable to manual polishing.

    2.2 The surface effect after deburring is uniform and controllable. The quality of manual deburring and polishing depends on the personal skill level of the worker. Some products may have clean burrs, while others may still have some residue. The surface quality of each product is different. Sometimes it may also cause product damage, resulting in a relatively high scrap rate.

    2.3 The running costs of parts deburring machines are extremely low. The one-time purchase cost of the machine starts from a few thousand dollars, and it can generally be used for many years. The choice of ordinary abrasive media depends on the actual conditions of the product parts that need to be processed, and the price ranges from a few dollars per kilogram to more than ten dollars, buying a few hundred kilograms at a time can usually take several months. The amount of finishing liquid is very small and the cost is almost negligible.
    Ordinary models can feed dozens of kilograms of workpieces at a time, and the deburring time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.
    On the other hand, in terms of saving labor costs, the advantages of automatic parts deburring machines are even greater. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

    2.4 In addition to the automatic deburring function, ShineTec’s parts deburring machine can also perform surface treatment technology of descaling, derusting, cleaning, chamfering, degreasing, decontaminating, brightening, burnishing, etc., powerful functions and wide applicability.

  • 3．Can you tell me how the parts deburring machine deburrs?
  • In order to solve the problems of low efficiency, low quality and high labor cost of manual deburring, ShineTec’s parts deburring machine is an automatic finishing and polishing machine. The main operating principle is to use a dedicated Tumbling Deburring Media are mixed with the product workpiece, an appropriate amount of water and chemical finishing liquid in a certain proportion, and put into the working barrel, mechanical movements such as vibrating, centrifugal high-speed rotation, disc rotation, and tumbling rolling rotation are used to rotate the abrasive media and the workpiece together in the barrel, and the cutting force of the abrasive surface is used to finish the burrs on the surface of the workpiece.

    There are four main product types of parts deburring machines. Each movement mode has its own advantages and disadvantages, and is suitable for different finishing, polishing and deburring needs. Vibratory deburring is the most common process method. If you need to process large quantities every day, such as product workpieces of hundreds of kilograms or more, then choose a vibrating deburring machine. If you need to process some small precision parts, the quantity is within tens of kilograms, the centrifugal barrel deburring process is the most suitable method. If you are looking for the fastest deburring process, then centrifugal disc deburring is the fastest polishing method. If you want to find the cheapest, lowest cost deburring process, go for the tumbling barrel deburring method.

  • 11. How to buy a parts deburring machine?
  • Before ordering, you need to send samples for process testing. If you are satisfied with the results, please refer to the following steps to confirm your ordering requirements:

    11.1 Power requirements. Our parts deburring machine requires 380V/3-phase/50Hz industrial power and is not suitable for civilian 220V/2-phase power. Special requests need to be confirmed in advance.

    11.2 Processing capability requirements. First estimate the quantity of your product that needs to be processed every day, your shift schedule, and confirm the machine model based on the process plan.

    11.3 Your product parts size. The workpiece within 300mm can be processed by all models, but the vibrating finisher is the most commonly used deburring equipment. For workpieces that are too long, a rectangular tub-shaped vibrating deburring machine is needed. Some small-sized precision parts require the use of a centrifugal barrel finisher. For workpieces within 100mm that need to be quickly deburred, a centrifugal disc finisher is the best choice. No afraid of deformation or bumping. Use a barrel tumbling finisher for thin workpieces within 300mm in length that are easy to adsorb to each other.

    11.3 Selection of deburring media. According to the effect of the sample, select the appropriate abrasive media, cutting strength, shape, and size.

    11.4 Wear resistance of tumbling media. Different cutting strength, shape, and size determine the different wear resistance properties of abrasive media when used. Tumbling media with heavy cutting force have smaller wear resistance than media with light cutting force due to the large grit size of corundum sand contained. The larger the product, the longer it will last and the more wear-resistant it will be. There are also different shapes with different wear resistance. For example, shapes such as spheres and cylinders are more durable than triangles and tri-star shapes.

    11.5 Finishing time. The deburring efficiency of each model is different. You should choose the appropriate model based on your production shift schedule, product output, and batch processing time requirements for finishing and polishing.

    11.6 The working intensity. The bowl of the vibrating deburring machine is open, making it easy to load materials; the centrifugal disc type is similar and easy to load and unload; the centrifugal barrel type has a smaller working barrel and a smaller opening, so it takes more time to load and unload. The opening of the tumbling barrel is also small, and the loading and unloading of materials is relatively slow; the overall labor intensity and loading and unloading time are stronger than the centrifugal disc/barrel type.

    If you want to buy a metal deburring machine, precision parts deburring machine, gear deburring machine, laser cutting deburring machine, plastic product deburring machine, ShineTec’s workpiece deburring and polishing machine should be able to meet your requirements.

  • 12. How to improve the finishing efficiency of parts deburring machine?
  • Some precautions during actual use can help improve the efficiency of the automatic deburring and polishing machine.

    12.1 Reasonable ratio of abrasive media to workpiece. The reasonable ratio of the two when loading and feeding is the key factor affecting the finishing and polishing efficiency. The most commonly used ratio is 3:1 abrasive to workpiece. Please refer to the table below to determine your usage:

    Abrasive media to workpiece volume ratio Typical application
    0 : 1 No tumbling media, self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 The same proportion of abrasive media and parts such as forgings, castings, etc., with very rough surfaces.
    2 : 1 Gentle finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for finishing copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for grinding and polishing ferrous metals.
    4 : 1 The ratio of non-ferrous metal workpieces with average efficiency. High polishing efficiency ratio for ferrous metal parts.
    5 : 1 More suitable for finishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing of non-ferrous metal products. Commonly used for pre-plating treatment with resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better finishing quality. Suitable for irregular shapes or fragile workpieces.
    Maximizing No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.


    12.2 Loading capacity. Too much or too little loading will affect the finishing efficiency of the machine. Please do not feed materials at 100% full load or less than 50%. Generally, the overall volume of the material after loading does not exceed 70% of the barrel volume, and the water surface does not exceed 80% of the barrel volume.

    12.3 Amount of finishing compound liquid. Too little dosage will definitely not play the role of the additive in accelerating grinding. Too much dosage will produce a large amount of foam, which will pollute the environment, and on the other hand, it will block the tumbling and rotating motion of the abrasive media and the workpiece, reducing the grinding efficiency.

    12.4 Suitable machine operating speed. This is a process that requires long-term experience accumulation. Polishing efficiency depends on the material and size of the tumbling media used, the amount of water and chemical compound added, and the running speed of the machine. Too little material input and high-speed machine operation speed will cause over-grinding of the product, affecting the overall size, accuracy or chamfering degree. Excessive material input and too low machine speed will cause insufficient movement of the workpiece inside the abrasive media, reduce cutting strength, and affect efficiency.

  • 13．How long does it take to deburr a workpiece with a parts deburring machine?
  • There are three factors that determine the finishing time it takes to a hardware deburring tumbler:

    13.1 The material and surface condition of the workpiece. The length, thickness, and location of burrs, flash, and sharp edges will all affect the processing time. In addition, the harder the workpiece is, the longer it will take. On the contrary, the softer the workpiece will be, the shorter the time will be.

    13.2 The choicing of polishing machines. Generally speaking, compared by finishing speed, centrifugal disc finisher > centrifugal barrel finisher > vibratory finisher > tumbling barrel finisher.

    13.3 The capacity of the machine. The larger the capacity of the machine, the greater the friction process between the abrasive media and the workpiece, and the faster the desired effect can be achieved.

  • 14. Is the parts deburring machine safe?
  • Compared with polishing processes such as angle grinders, belt sanders, or chemical finishing used for manual polishing, the parts deburring machine is the most secure.
    As long as you follow regular daily maintenance and pay more attention to whether the power cord is broken or the copper wire is exposed, the machine will be safe for daily use.
    Wastewater will be produced during the deburring process, which can be recycled and will not affect the environment. Therefore, there are no safety issues in environmental protection.

    Ordinary models can feed dozens of kilograms of workpieces at a time, and the deburring time for a batch is generally 30-60 minutes. The direct cost of finishing and polishing when evenly distributed to each product is minimal.
    On the other hand, the advantages of automatic deburring tumbler are even greater in terms of saving labor costs. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

    4.4 In addition to the automatic deburring function, ShineTec’s deburring tumbler can also perform surface treatment processes such as descaling, derusting, deflashing, smoothing, cleaning, chamfering, degreasing, decontaminating, and improvement of surface brightness. It features powerful functions and wide applicability. If you don’t know how to quickly deburr your product, we recommend you learn more about our fully automatic deburring tumbler.
  • 5. What types of deburring tumbler do ShineTec have?
  • According to different operating modes, our deburring tumblers are divided into the following four types:

    5.1 Vibratory Deburring Machine. It is a general-purpose deburring machine. The spiral vibration method is used to drive the deburring media and the workpiece to move together to achieve the vibration deburring effect.

    5.2 Centrifugal Barrel Deburring Machine. It is suitable for rapid deburring of precision parts and components. It is similar to the operation of a Ferris wheel. The motor drives the large centrifugal disk to rotate, allowing the four barrels on the disk to rotate at high speed, driving the deburring media and the workpiece to move together to achieve the centrifugal deburring effect.

    5.3 Centrifugal Disc Deburring Machine. It is the fastest deburring equipment. The chassis drives the barrel to rotate at high speed on the horizontal plane. The deburring media and workpiece also tumble and rotate in the barrel to achieve the disc deburring effect.

    5.4 Tumbling Barrel Deburring Machine. It is the simplest structure and the lowest cost deburring method. The barrel rolls around the central axis, and the deburring media in the barrel rolls together with the workpiece to achieve the tumbling deburring effect.

  • 6. What does dry and wet deburring mean?
  • Dry finishing is a deburring and polishing method that only adds finishing media, workpieces, polishing paste or polishing powder when the machine is running, and does not add water.
    Wet finishing is a deburring and polishing method that requires adding an appropriate amount of chemical liquid and water to the finishing media and workpiece when the machine is running.
    Wet finishing is the most widely used finishing and polishing process. For most common materials and general-purpose products, wet deburring is the most suitable method. With the assistance of water and liquid finishing compound, it can speed up the deburring process, reduce bumps, lower the machine operating temperature, and avoid dust producing, extending the service life of the machine.
    Dry finishing is mainly used in the polishing process of some products that cannot come into contact with water, such as the deburring process of some easily corroded metal products, wooden handicrafts, precision parts, and the drying process of products after wet finishing.

    10.1 Processing capability. We compare according to the largest models in their respective categories. The vibrating deburring machine can process tons of products at a time. The largest barrel deburring machine can also achieve such processing capabilities. The centrifugal disc deburring machine can reach 1-200 kg, the centrifugal barrel deburring machine can handle about 2-300 kg. Taking into account the processing time required for a complete batch, the processing capacity can be arranged in the following order: vibratory finisher > tumbling barrel finisher > centrifugal barrel finisher > centrifugal disc finisher.

    10.2 Machine noise. vibratory tumbler > centrifugal disc tumbler > centrifugal barrel tumbler > tumbling barrel tumbler.

    10.3 Deburring time. centrifugal disc tumbler > centrifugal barrel tumbler > vibratory tumbler > tumbling barrel tumbler.

    10.4 Deburring cost. centrifugal disc tumbler > centrifugal barrel tumbler > vibratory tumbler > tumbling barrel tumbler.

    10.5 Cutting force. centrifugal disc tumbler > centrifugal barrel tumbler > tumbling barrel tumbler > vibratory tumbler.

  • 11．What kind of daily maintenance can extend the service life of the deburring tumbler?
  • 11.1 Do not overload the machine. Each automatic deburring tumbler has a rated usage capacity, so the machine cannot be overloaded in order to improve production efficiency. Generally, the material loading capacity of the entire machine should not exceed 70% of the total load capacity of the machine.

    11.2 Maintain regular maintenance. The specific work content involves the lubrication of the motor, inspection of the PU lining, inspection of the integrity of mechanical components, inspection of operating temperature, etc.

    11.3 Inspection of electrical systems. Check whether the components in the electrical control box are aging, and whether the power cord is broken or the copper wire is exposed.

  • 12．How to buy a deburring tumbler?
  • We are a manufacturer of deburring tumbler. Before ordering, you need to send samples for process testing. If you are satisfied with the results, please refer to the following steps to confirm your ordering requirements:

    12.1 Power requirements. Our parts deburring machine requires 380V/3-phase/50Hz industrial power and is not suitable for civilian 220V/2-phase power. Special requests need to be confirmed in advance.

    12.2 Processing capability requirements. First estimate the quantity of your product that needs to be processed every day, your shift schedule, and confirm the machine model based on the process plan.

    12.3 Your product parts size. The workpiece within 300mm can be processed by all models, but the vibrating finisher is the most commonly used deburring equipment. For workpieces that are too long, a rectangular tub deburring machine is needed. Some small-sized precision parts require the use of a centrifugal barrel finisher. For workpieces within 100mm that need to be quickly deburred, a centrifugal disc finisher is the best choice. No afraid of deformation or bumping. Use a barrel tumbling finisher for thin workpieces within 300mm in length that are easy to adsorb to each other.

    12.3 Selection of deburring media. According to the effect of the sample, select the appropriate abrasive media, cutting strength, shape, and size.

    12.4 Durability of tumbling media. Different cutting strength, shape, and size determine the different wear resistance properties of abrasive media when used. Tumbling media with heavy cutting force have smaller wear resistance than media with light cutting force due to the large grit size of corundum sand contained. The larger the product, the longer it will last and the more wear-resistant it will be. There are also different shapes with different wear resistance. For example, shapes such as spheres and cylinders are more durable than triangles and tri-star shapes.

    12.5 Finishing time. The deburring efficiency of each model is different. You should choose the appropriate model based on your production shift schedule, product output, and batch processing time requirements for finishing and polishing.

    12.6 The working intensity. The bowl of the vibrating deburring machine is open, making it easy to load materials; the centrifugal disc type is similar and easy to load and unload; the centrifugal barrel type has a smaller working barrel and a smaller opening, so it takes more time to load and unload. The opening of the tumbling barrel is also small, and the loading and unloading of materials is relatively slow; the overall labor intensity and loading and unloading time are stronger than the centrifugal disc/barrel type.

  • 13．What tips can improve the deburring efficiency of deburring tumbler?
  • Some precautions during actual use can help improve the efficiency of the automatic deburring and polishing machine.

    13.1 Reasonable ratio of abrasive media to workpiece. The reasonable ratio of the two when loading and feeding is the key factor affecting the finishing and polishing efficiency. The most commonly used ratio is 3:1 abrasive to workpiece. Please refer to the table below to determine your usage:

    Abrasive media to workpiece volume ratio Typical application
    0 : 1 No tumbling media, self-finishing and polishing, such as some decorative stones for handicrafts.
    1 : 1 The same proportion of abrasive media and parts such as forgings, castings, etc., with very rough surfaces.
    2 : 1 Gentle finishing, allowing workpieces to collide with each other.
    3 : 1 Minimum ratio for finishing copper, aluminum, zinc and other non-ferrous metal workpieces. The workpieces may collide with each other, so the ratio is suitable for grinding and polishing ferrous metals.
    4 : 1 The ratio of non-ferrous metal workpieces with average efficiency. High polishing efficiency ratio for ferrous metal parts.
    5 : 1 More suitable for finishing non-ferrous metal parts. Workpieces rarely collide with each other.
    6 : 1 Suitable for finishing of non-ferrous metal products. Commonly used for pre-plating treatment with resin media and aluminum and zinc alloy workpieces.
    8 : 1 Suitable for finishing of non-ferrous metals or precision parts. Less surface roughness and smoothness.
    10:1~20:1 Better finishing quality. Suitable for irregular shapes or fragile workpieces.
    Maximizing No collision between workpieces. One machine polishes one part or each workpiece needs to be separated.


    13.2 Loading capacity. Too much or too little loading will affect the finishing efficiency of the machine. Please do not feed materials at 100% full load or less than 50%. Generally, the overall volume of the material after loading does not exceed 70% of the barrel volume, and the water surface does not exceed 80% of the barrel volume.

    13.3 Amount of finishing compound liquid. Too little dosage will definitely not play the role of the additive in accelerating grinding. Too much dosage will produce a large amount of foam, which will pollute the environment, and on the other hand, it will block the tumbling and rotating motion of the abrasive media and the workpiece, reducing the grinding efficiency.

    13.4 Suitable machine operating speed. This is a process that requires long-term experience accumulation. Polishing efficiency depends on the material and size of the tumbling media used, the amount of water and chemical finishing liquid added, and the running speed of the machine. Too little material input and high-speed machine operation speed will cause over-grinding of the product, affecting the overall size, accuracy or chamfering degree. Excessive material input and too low machine speed will cause insufficient movement of the workpiece inside the abrasive media, reduce cutting strength, and affect efficiency.

  • 14. How long does it take for a deburring tumbler to work?
  • It depends on the specifics of your product. Generally speaking, soft metals such as aluminum alloys and zinc alloys can achieve a satisfactory effect in less than an hour, while hard product workpieces such as stainless steel, titanium alloys, and cemented carbide may require Requires more than 2 hours of deburring time.
    In addition, the size of the machine used also affects the processing time. The bigger the machine, the less time it takes to grind.

What is the tumbling barrel deburring machine?

About Tumbling Barrel Deburring Machine

  • 1．What is the tumbling barrel deburring machine?
  • Tumbling barrel deburring machines are also called rotary barrel finishing machines, rotating tumbler. They use mechanical methods to automatically deburr, descale, derust, finish parts and workpieces in large quantities. Machinery and equipment for surface treatment processes such as deflashing, cleaning, chamfering, degreasing, decontaminating, brightening and improving surface brightness. Its operating principle is to put the product to be polished and the finishing media into the working barrel of the machine, allowing the abrasive and the workpiece to tumble and rotate together, forcing the abrasive and the workpiece to collide and rub against each other to achieve the surface cutting effect.
    The tumbling barrel polishing machine is the simplest structure and the oldest deburring mechanical equipment. The motor drives the barrel to rotate around the central X-axis through a chain or transmission gear. The deburring media in the barrel and the workpiece are turned over and rubbed against each other to achieve the deburring and polishing effect.

  • 2. What is the difference between tumbling barrel deburring and other deburring processes?

  • 2.1 Tumbling barrel deburring is the most traditional mechanical polishing process. Their deburring and polishing principles are similar. The workpiece and the deburring media are mixed together to achieve the deburring effect. The difference is that the barrel tumbler takes the longest time to polish and remove burrs. It is the mechanical equipment tool with the lowest finishing efficiency, but at the same time it is the process equipment with the best surface polishing quality.

    Comparing deburring and cutting efficiency, it can be arranged in this order:
    Centrifugal disc deburring machine > Centrifugal barrel deburring machine > Vibratory deburring machine > Tumbling barrel deburring machine.

    Comparing surface polishing quality, it can be arranged in this order:
    Barrel tumbler > Centrifugal barrel tumbler > Vibrating tumbler > Centrifugal disc tumbler.

    2.2 The tumbling barrel deburring machine uses the dry finishing process when finely deburring and polishing the brightness. That is, the abrasive media and the workpiece are directly mixed together, an appropriate amount of polishing paste is added, and the finishing and polishing is performed directly in the barrel without adding water. Other finishing machines are not allowed to use dry finishing process.

  • 3．Can you tell me how a tumbling barrel deburring machine works?
  • Put the tumbling finising media, the parts to be polished, water, and polishing fluid into the barrel deburring machine according to the corresponding proportions, close the sealing cover of the barrel to make it watertight, and then start the machine. This process can also be called tumbling finishing and polishing process. The abrasive media and the workpiece collide and rub against each other in the barrel, automatically completing the cutting process, reducing the surface roughness of the product, and achieving deburring, descaling, deflashing, chamfering, brightening, burnishing. It is currently the lowest cost, most mature technology and most widely used deburring and polishing solution.

    Since the rotation speed of the barrel is very slow, usually within 50 RPM, the overall processing time of rough finishing, deburring and fine finishing and polishing for each batch will be more than ten hours. It is the slowest finishing and polishing equipment.

    Precision polishing are performed using a dry finishing process. Generally, particle-shaped mirror polishing media with smaller external dimensions are used, such as Corncob polishing media, Walnut shell polishing media, bamboo wood chip, 3P polishing media and other polishing media, with polishing paste, without adding water, can simulate manual polishing with a cloth wheel, so that the surface of the workpiece can achieve a mirror-like polishing effect.

  • 4. What are the benefits of using a tumbling barrel deburring machine to polish parts?
  • Compared with manual polishing, there are definitely many advantages:

    4.1 Automatic large-scale mechanized deburring and polishing. Although the barrel deburring machine takes a relatively long time to finish and polish at one time, dozens hundreds or even tons of workpieces can be put into a batch, making the unit processing time advantage greater.

    4.2 Automatically remove rust and scale. Surface problems such as turning lines and mold lines can also be removed. This is the same as other tumbling finishing machines.

    4.3 Automatic chamfering. Products can be chamfered quickly.

    4.4 Improve surface finish and increase brightness. Make the product surface smoother and brighter. This is the strength of the barrel polishing machine. Its surface finish is of the highest quality.

    4.5 Automatic cleaning and degreasing. It can automatically remove dust, dirt, sludge and other phenomena adsorbed on the surface of the workpiece.

  • 5. Is the operating cost of a tumbling barrel deburring machine high?
  • Compared with manual finishing and polishing, the cost of barrel deburring machine can be said to be very low.
    This is the cheapest automatic finishing and polishing equipment. The one-time purchase cost of the machine can start from several thousand dollars, and it can generally be used for many years. The choice of ordinary abrasive media depends on the actual situation of the product parts that need to be processed, and the price ranges from a few dollars per kilogram to more than ten dollars. Etc., buying a few hundred kilograms at a time can generally last for months or even years. The amount of polishing compound is very small and the cost is almost negligible.
    The product workpiece can be fed with about tens of kilograms of material at a time in the smallest tumbling deburring machine. The finishing processing time for a batch is generally 2 hours. The direct cost of deburring and polishing when evenly distributed to each product is minimal.

    On the other hand, the advantage of using a barrel tumbling deburring machine is even greater in terms of saving labor costs. As long as workers need to handle it when loading and unloading materials, the machine can be operated unattended, which greatly saves labor costs.

  • 6. What optional configurations are available for ShineTec’s tumbling barrel deburring machine?
  • 6.1 protecting mask. A protective net cover can be installed outside the barrel to prevent collisions between people or materials during machine operation.

    6.2 Vibratory separator can be used to screen the abrasive media and parts. It can be used as an auxiliary equipment for the tumbling barrel deburring machine and can be configured separately.

    6.3 Frequency conversion speed regulation function. A frequency converter is also installed in the electrical control box, which is suitable for adjusting the machine at different operating speeds.

  • 7．Which model of tumbling barrel deburring machine should I choose?
  • You should choose which type of tumbling barrel deburring machine based on the shape, size, material, surface quality requirements, processing quantity and other factors of your product parts.
    There is no limit to the workpiece material suitable for the tumbling barrel deburring machine, and the length is generally within 0.5 meters. However, one requirement is that the workpiece cannot be easily deformed or may be bumped. Because the vertical drop is relatively large when the barrel is turned over, and the impact force of the abrasive media on the workpiece is also large, soft long strips or thin products are easily deformed and damaged.

  • 8. How does ShineTec ensure the quality of the tumbling barrel deburring machine?
  • 8.1 Quality assurance of raw materials. Because the lining of the working barrel of the machine can be rubber or PU, this lining is a wearing part and needs to be replaced regularly. The wear resistance of the colloid is a key quality indicator. The raw materials of our colloids come from major domestic manufacturers and products from Dow Chemical of the United States, so the quality can be guaranteed.

    8.2 Reliable motor quality. The motor is a key component related to product quality. The three-phase asynchronous motors used in our barrel deburring machines all come from well-known professional motor manufacturers in Shanghai, and there is no problem with their quality.

    8.3 Electrical accessories. All are purchased from domestic first-tier manufacturers such as Chint and Delixi.

    8.4 Steel plate profiles. Purchased from Shanghai Baosteel Products.

    8.5 Manufacturing Guaranteed. Product production is controlled by skilled workers with many years of front-line production experience, adhering to the spirit of craftsmanship to ensure product quality.

  • 9. How to order a tumbling barrel deburring machine?
  • Please confirm the following basic requirements first:

    9.1 Please send samples first and we will conduct samples testing to determine the best finishing and polishing process.

    9.2 Evaluate the quantity of your product components and workpieces that need to be processed every day? What surface quality is required?

    9.3 Choose the appropriate machine processing capacity, provide the space size of your work area, and determine the machine model.

    9.4 Confirm whether additional auxiliary equipment is required, such as vibratory separator, additional wearing spare parts, etc.

    9.5 The commonly used power supply for the machine is 380V/3-phase/50Hz. Are there any special power requirements?
    After clarifying the above details, you can place an order.

  • 10．What abrasive media can be used in barrel deburring machines?
  • Abrasive media for rough finishing, fine finishing and polishing:

    10.1 The abrasive used for rough finishing is mainly ceramic deburring media, which is divided into heavy cutting force, medium cutting force and light cutting force.

    10.2 Abrasives for fine fininishing include white corundum finishing media, chrome corundum finishing media, 3P finishing media, etc. Since the grit size of the micropowder contained in them is very fine, some of which are nearly 2000-3000 mesh, it can continuously polish the workpiece surface. Continuous micro-cutting creates a more delicate surface roughness.

    10.3 Polishing media include high-alumina porcelain media, high-density porcelain media (high-alumina porcelain polishing media with an alumina content of more than 95%), stainless steel media, corncob media, walnut shell media, bamboo grain chip, wood grain chip. The main purpose is to improve the gloss and brightness of the workpiece surface.
  • 11. What kind of power supply does the tumbling barrel deburring machine use?
  • In China, it is generally 380V/3-phase/50Hz.
  • 12．What is the daily maintenance of the tumbling barrel deburring machine?
  • Routine maintenance of the tumbling barrel deburring machine is crucial to extending the service life of the machine. Routine maintenance includes the following:

    12.1 Inspection of the lining on the inner wall of the working barrel. Daily use of the machine will cause wear and tear on the lining in the barrel. Do you need to regularly check whether the lining on the inner wall has any holes or wear? If this happens, it needs to be replaced immediately, otherwise it will cause damage to the barrel.

    12.2 After each loading, check whether the water added in the barrel is too little or too much. The water surface of the barrel polishing machine should not exceed the material by 20mm. Too much water will buffer the force exerted by the abrasive on the workpiece surface and reduce the deburring efficiency; Too little water will cause damage to the surface of the workpiece, the abrasive will easily break and the colloid in the barrel will wear too quickly.

    12.3 Loading capacity of tumbling finishing media and workpiece. We recommend that the ratio of abrasives to workpieces is 3:1. Too little abrasives will cause collisions between workpieces and damage the product surface; too much abrasives will reduce the grinding efficiency of the product.
    Note that the overall volume of materials and water in the working barrel does not exceed 60% of the inner volume of the barrel.

    12.4 Check the abrasive media debris for stuck holes and seams. The abrasives in the barrel will become smaller and smaller after long-term use. In addition, a lot of debris formed by the workpiece and the abrasives will be produced during the grinding process. If the width of these impurities is less than 1mm, they may block the holes and seams inside the parts, affecting the deburring and polishing effect of the workpiece. If stuck holes occur, the tumbling finishing media should be screened to remove the debris and impurities, and the machine should be restarted.

    12.5 Water temperature detection. Long-term operation of the machine will cause the temperature inside the working barrel to become very high. Excessively high water temperature will accelerate the aging rate of the colloid, so if your product needs to be polished for more than ten hours, please use a rubber-lined barrel, because the high temperature resistance of rubber is better than that of PU lining.

  • 13．What industries can the tumbling barrel deburring machine be used in?
  • Barrel deburring machines are widely used in automotive parts, aerospace, medical equipment, mechanical parts, plastic products, 3C digital, metal casting, electronic devices, hardware parts, kitchen supplies, 3D printing, textile workpieces, powder metallurgy, electrical components, It is widely used in industries such as minting, jewelry, instrumentation, and handicraft accessories.
  • 14．Are there any disadvantages to tumbling barrel deburring machines?
  • The main disadvantage is that it cannot control a specific part of the surface of the finishing product, because it is an overall grinding process. For example, for a product with inconsistent sizes at both ends, you want to make the two ends of the product uniform in size by finishing only the large end, but this is not possible.

    The surface quality cannot achieve the effect of mirror polishing.

    Some inner holes and cross holes that are too deep and too thin, such as inner surfaces exceeding 50mm, cannot be finished and polished.

    Too long burrs and flash cannot be processed. For example, burrs and flash exceeding 2mm.

    It is not suitable for some workpiece that are easy to deform and are afraid of being bumped.

  • 15. Does the tumbling barrel deburring machine require specially trained technicians to operate it?
  • Unnecessary. The operation of this machine is very simple. Just put the abrasive media, workpiece, water and appropriate amount of chemical finishing liquid into the barrel. The machine has a timing function. After starting the machine, the worker can leave to handle other matters. When the set time is up, the machine will automatically shut down. All that is needed is to unload the material and take out the workpiece to complete the finishing and polishing process. Therefore no special technical training is required for employees.
  • 16. What surface treatments can the tumbling barrel deburring machine perform?
  • 16.1 Deburring, deflashing, chamfering. Defects caused during workpiece processing that may cause harm to users can be automatically removed in batches.

    16.2 Derusting and descaling. Surface problems such as turning lines and mold lines can also be removed.

    16.3 Improve surface finish and increase brightness. Make the product surface smoother and brighter.

    16.4 Cleaning and degreasing. It can automatically remove dust, dirt, sludge and other phenomena adsorbed on the surface of the workpiece.

  • 17．What are the tumbling media suitable for barrel deburring machines?
  • Depending on the shape, material, specifications and sizes of your parts, you need to choose different types of abrasive media. Abrasives that can be used in the machine are: ceramic deburring media, porcelain polishing media, high-density porcelain media, plastic media, white corundum polishing media, 3P precise polishing media, walnut shell mirror polishing media , corncob drying mediaWait.
    Improper selection of abrasives during the finishing process will affect grinding efficiency and may even cause damage to the workpiece.
