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.

  • 1. What are laser cut parts?
  • Laser cutting parts are workpieces produced using laser cutting processing technology. It is used in spare parts for products with high precision requirements in various industrial fields.
  • 2. Why do laser cut parts need to be deburred?
  • Laser-cut parts produced during processing must undergo surface treatment processes such as deburring and polishing.
    The benefits of applying this finishing process are as follows:

    2.1 Remove oxide layer.
    Laser cutting uses gases such as oxygen or carbon dioxide as assistance. These gases will form an oxide layer on the surface of the product during high-temperature cutting. It may corrode or rust the parts, so you must polish these cutting parts to remove the oxide layer.

    2.2 Improve product appearance quality.
    The appearance of a product affects its quality. If you are a practitioner of machined parts, using the deburring and finishing process can provide a beautiful and uniform appearance to the workpiece.

    2.3 Repair product surface quality.
    The laser cutting process may cause certain appearance defects to the workpiece, such as silk lines, cracks, pitting, etc. Through finishing and polishing, these defects can be repaired, thereby improving product yield and reducing production costs.

    2.4 Chamfer processing.
    Laser cutting will produce sharp edges or corners, which may cause harm to users during use.
    After chamfering, sharp edges can be removed and sharp corners can be smoothed and rounded. It can also reduce product stress, which affects product durability and quality stability.

    2.5 Produces a special matte effect.
    Some products may require a matte finish. This demand can be met by using appropriate tumbling abrasive media and correct finishing and polishing processes.

    2.6 Improve security.
    Flashes, sharp edges, and sharp corners on the surface of the workpiece may cause harm to the user. Therefore, it is necessary to use a deburring and finishing machine for polishing in the subsequent process to improve the surface quality of the product.
  • 3. Can you explain the method of deburring from laser cutting workpieces?
  • Currently, many laser-cut parts are still polished manually. For example, traditional deburring methods such as sandpaper, power tools with grinding heads, belt sanders, and grinding wheels are used.
    These backward polishing methods are inefficient, not environmentally friendly, and also bring many safety hazards.
    Some new deburring processes include ultrasonic, thermal energy, electrochemical, sandblasting, shot blasting and other methods. Each has its own characteristics and limitations.
    The tumbling finishing and polishing process we currently provide is a low-cost, high-volume, and high-efficiency mechanized deburring and polishing method, which is especially suitable for some special-shaped laser cutting parts with complex cavities.
  • 4. What kind of equipment is the laser cutting workpiece deburring machine?
  • Laser cutting parts polishing machine is a machine used to deburr, descale, chamfer, clean, degrease, and polish and brighten laser cut products. Using the right tumbling abrasive media and choosing the right machine type will make your process more efficient. At the same time, it can also reduce labor costs, reduce labor intensity, and improve production efficiency.
  • 5. What are the advantages of laser cutting parts finishing and polishing machines?
  • The benefits of laser cutting parts deburring and polishing machines are as follows:

    5.1 Lower processing costs. Manual deburring requires high labor costs, more tools and abrasive material losses. Our finishing and polishing machine for laser cutting is a one-time investment. Later, you only need to purchase some tumbling media, chemical compound liquid regularly. Only very little manual participation is required during the processing, so labor costs will be greatly reduced.

    5.2 Save time. It is obvious that machine deburring and polishing can greatly save operating time compared to manual polishing. Your productivity can be greatly improved.

    5.3 Non-destructive surface treatment. Use suitable matching tumbling finishing media and choose the correct mass finishing equipment. After completing the polishing processes such as deburring and descaling, your product workpiece will not change in shape, position and size. It is a lossless process. If it is polished by hand, due to the different handling strength of each workpiece, it may have an impact on the size of the product, and each one is not uniform.

    5.4 Get the best surface quality. The quality of product appearance determines the quality of the product. Manual polishing cannot achieve a consistently stable product surface quality. But a polishing machine can give you a consistent look. Finishing time and surface roughness level can be controlled, helping you to stand out in the fierce market competition.

    5.5 Save labor. At present, the labor cost of product polishing process accounts for a large proportion of the overall product cost. ShineTec’s finishing and polishing machine allows a single worker to perform multiple batches of mechanized deburring, descaling and polishing, which will save a lot of labor costs and greatly reduce labor intensity.

    5.6 High-volume polishing. Our finishing and polishing solutions are characterized by high-volume, high-efficiency, mechanized automatic finishing. Laser cutting parts of different shapes and sizes can be processed in the same polishing machine. If combined with automated assembly lines, your production efficiency and product quality can be greatly improved.

    5.7 Extremely low maintenance costs. The daily maintenance cost of the machine and the loss of tumbling media are the most important factors for business owners to consider. ShineTec’s finishing and polishing machines have almost no maintenance costs. In addition to regularly adding a little lubricant to the motor, there are no other special tools that need to be purchased.

    5.8 No specially trained operators are required. Manual finishing and polishing requires special training for operators first. This is a high labor cost and an uncontrollable link in the production process. The mass finishing machines we provide are very simple to operate. Workers only need to load and unload materials. The polishing process of the machine does not require manual participation.

    5.9 Safe production environment. Laser-cut parts may have sharp corners, burrs or flash edges, which may cause harm to front-line workers. Debris generated during manual polishing may also enter people’s eyes or cause skin allergic reactions. Using finishing and polishing machines can avoid these phenomena. Provide production workers with a safe and reliable production working environment.

    5.10 Improve the adhesion of electroplating, paint and coatings. Some laser-cut parts may require electroplating, painting or coating treatment in the final stage. If polished by hand, the appearance of the product will be inconsistent, resulting in unstable surface quality of the finished product. After using our tumbling finishing and polishing, there will be a uniform surface quality before subsequent surface treatment, and a reliable and stable product quality will be obtained later.
  • 6. What types of laser cutting parts deburring machines does ShineTec have?
  • ShineTec provides different tumbling finishing and polishing machines that can be used to polish laser cut parts. They are vibratory/vibrating deburring and finishing machines, centrifugal barrel finishing machines, centrifugal disc finishing machines, and barrel tumbling finishing machines. Depending on the material, shape, specification and size of the workpiece, we can select the correct machine model and matching ceramic deburring media, porcelain polishing media and other tumbling media to meet your process requirements.

    6.1 Vibratory Finishing Machine. Vibration type, also called vibrating finishing and polishing machine, is the most commonly used equipment for deburring and polishing laser cutting parts. It is characterized by strong applicability, large processing capacity, easy operation, convenient loading and unloading, and controllable process. Generally, small and medium-sized special-shaped workpieces can be processed. The disadvantage is that it is not easy to penetrate deep into the cavity.

    6.2 Centrifugal Barrel Finishing Machine。 The centrifugal barrel finishing type, is a device suitable for finishing and polishing some small-sized laser cutting workpieces. It is characterized by strong cutting force, short processing time, and the ability to penetrate deep into the inner holes and gaps of the workpiece. The disadvantage is that the processing capacity is not large at one time, and loading and unloading is time-consuming.

    6.3 Centrfugal Disc Finishing Machine。 The centrifugal disc finishing machine is suitable for processing some laser cutting workpiece products with large burrs. It is characterized by the strongest cutting force, short processing time and easy loading and unloading. Generally speaking, compared with vibratory polishing machines, the finishing and polishing efficiency can be increased by about 30 times. The disadvantage is that it is not suitable for some thin laser cutting parts and is easy to deform or get stuck in the gaps of the machine chassis.

    6.4 Tumbling Barrel Finishing Machine. Also called rotary barrel polishing machine. It is suitable for parts with high surface polishing brightness and gloss requirements. It is characterized by slow work and careful work, combined with special abrasive media, such as walnut shells, corn cobs, wood, bamboo chips and other plant abrasives, and polishing paste, which can bring a mirror-like shiny surface effect. The disadvantage is that the processing time is slow and the efficiency is low. Some parts may need to be processed for several days at a time. It is also not suitable for some easily deformed laser cutting workpieces.
  • 7. What deburring abrasive media are used in laser cutting parts deburring machines?
  • The tumbling media used for finishing and polishing laser cutting parts are also called mass finishing media. ShineTec offers a wide range of abrasive media. The factors that affect the quality of abrasives mainly include cutting force, wear resistance, specific gravity density, hardness, appearance size, color and other indicators. High-quality raw materials and scientific production process control bring high-quality abrasive media. The main types are as follows:

    7.1 Brown Corundum Ceramic Deburring Media. Brown corundum ceramic media is a commonly used abrasive material used for deburring, descaling, deflashing and finishing of laser cutting parts. Suitable for hard metal parts. The deburring ceramic media provided by ShineTec are available in triangular, cylindrical, spherical, conical, three-star, oval, pyramid, tetrahedral and other shapes. Each shape has different specifications and sizes. Each abrasive media also has different cutting force levels. Heavy cutting force deburring media are used for workpieces that require a lot of finishing and cutting force, and light cutting force deburring media are used for some product workpieces that require a lot of smoothness.

    7.2 High Alumina Porcelain Media. High-alumina porcelain media do not contain brown corundum sand with strong cutting force. Therefore, this tumbling polishing media has no cutting force and cannot be used for deburring, descaling and other processing. Because of the high alumina content, the polishing abrasive media formed after final sintering has a large specific gravity, dense internal structure, and strong hardness. It is suitable for polishing processes that improve the surface brightness of laser cutting workpieces. The greater the specific density, the higher the surface brightness of the treated product. The appearance color is porcelain white, and the shapes are generally spherical, triangular, cylindrical, oval, etc.

    7.3 Resin Media。 Tumbling resin media are also called Plastic Media, Polyester Media. Because they have a moderately elastic surface, they are suitable for polishing and polishing laser cutting parts produced from soft metals such as aluminum alloys. Resin grinding stone is an abrasive material made of resin mixed with corundum sand powder through a curing reaction. It is also suitable for deburring and polishing workpieces made of materials such as copper and plastic. ShineTec can provide resin abrasives in conical, pyramid, triangular, three-star, bullet and other shapes. Brown corundum sand containing different mesh numbers can bring different cutting forces, and can also be divided into heavy cutting, medium cutting, and light cutting grades.

    7.4 Stainless Steel Media。 This polishing media is made of stainless steel. Because it has no cutting force and a density of up to 7.8 g/cm3, it is also used to polish the surface brightness of laser-cut parts. The specific gravity is more than three times higher than that of high-alumina porcelain polishing media, and the surface brightness obtained after polishing is also far superior to that of high-alumina porcelain polishing media. The shapes include ball, ballcone (ufo), and pin shapes, which are suitable for brightening metal workpieces.

    7.5 Mirror Polishing Media. It is mainly produced by processing walnut shells, corn cobs, cork pellets, bamboo chips, etc. In addition to their finishing and polishing functions, walnut shells and corncobs are also used to dry cleaned workpieces in a vibration dryer because of their strong water absorption. Vegetable tumbling media are mainly used to polish the surface brightness of laser cutting parts. When used in conjunction with a barrel tumbling polishing machine, a mirror-like bright effect can be achieved.
  • 8. Which products’ laser-cut parts can be used with this tumbling finishing deburring and polishing machine?
  • The laser cutting parts polishing machine provided by ShineTec can handle workpieces made of the following materials:

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.

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

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

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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 4. What types of parts deburring machines are available from ShineTec?
  • According to different operating modes, parts deburring machines are divided into the following four types:

    4.1 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.

    4.2 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.

    4.3 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.

    4.4 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.

  • 5. How much does a parts deburring machine cost?
  • The price of the machine ranges from several thousand to tens of thousands. The price of deburring media generally costs around a few thousand dollars for an initial order of several hundred kilograms. Such an automatic deburring and polishing solution can be said to be quite economical.
    However, the economic benefits brought by using a automatic parts deburring machine are very high. If your products still use manual finishing and polishing, we can conduct a calculation of the processing cost to see how much our workpiece deburring and polishing machine can save you.

  • 6. What kind of abrasive media do parts deburring machines use?
  • Because our parts deburring machines can be used to handle a variety of surface treatment process requirements, the tumbling finishing media provided are divided into three types: rough finishing, fine finishing and polishing:

    6.1 Ceramic tumbling media for rough finishing, mainly include Ceramic Deburring Media, Resin Finishing Media , divided into heavy cutting force, medium cutting force and light cutting force.

    6.2 Fine finishing media, include white corundum finishing media, chrome corundum finishing media, 3P finishing 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.

    6.3 Tumbling polishing media include high alumina porcelain polishing media, high-density porcelain polishing media (high-alumina porcelain media with an alumina content of more than 95%), stainless steel polishing 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.

  • 7．What kind of parts deburring machine is a good and qualified machine?
  • To measure whether a parts deburring machine is qualified or not, it mainly depends on the quality of the raw materials used and the quality control during the production and manufacturing process.

    7.1 Quality assurance of raw materials. Because the PU lining in the working barrel of the machine is a wearing part and needs to be replaced regularly, the wear resistance of the PU lining is a key quality indicator. The raw materials of our PU come from American Dow Chemical products, and the quality can be guaranteed.

    7.2 Reliable motor quality. The motor used in the parts deburring machine is a key component related to product quality. Our motors, including vertical vibrating motors, speed-regulating motors, and three-phase asynchronous motors, all come from well-known professional motor manufacturers such as Wuxi and Shanghai, and their quality is reliably guaranteed.

    9.1 Vibratory deburring machine. It is a general-purpose finishing machine. The spiral vibrating method is used to drive the tumbling finishing media and the workpiece to move together to achieve the deburring, polishing effect.

    9.2 Centrifugal barrel deburring machine. It is suitable for rapid deburring of precision parts. 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 abrasive and the workpiece to move together to achieve the deburring and polishing effect.

    9.3 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 abrasive media and workpiece also tumble and rotate in the barrel to achieve the deburring and polishing effect.

    9.4 Tumbling barrel deburring machine. It is the simplest structure and the lowest cost deburring method. The barrel rolls around the central axis, and the tumbling media in the barrel rolls together with the workpiece to achieve the finishing, polishing effect.

    9.5 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. What kind of daily maintenance can extend the service life of the parts deburring machine?
  • As a manufacturer of automatic deburring machines, we recommend the following daily maintenance measures:

    10.1 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?

    10.2 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 gel damaged? Is there any water leakage from the sealing cover?

    10.3 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?

    10.4 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.

  • 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.
