What is resin media?

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.

  • 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.

  • 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.
    We can customize special sizes according to the shape and size of your product parts.

What is the ceramic 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.

What is the finishing media?

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.
    Every user of abrasive media wants to buy high-quality abrasives with fast grinding time, high surface quality and strong wear resistance. Maybe you are looking for where is the best tumbling abrasive media manufacturer? Please contact us. ShineTec masters the key technologies of abrasive production and manufacturing and can provide you with the most cost-effective abrasive media.
  • 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.

    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.

  • 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.

    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.

    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.

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.

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.

About Barrel Finishing Machine

  • 1．What is the barrel finishing machine?
  • Barrel Finishing Machine 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 rotary barrel tumbling 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 barrel finishing and other finishing processes?

  • 2.1 barrel finishing 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 rotary barrel tumbling 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 barrel finishing 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 barrel finishing 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 barrel finishing machine high?
  • Compared with manual finishing and polishing, the cost of rotary barrel tumbling 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 barrel finishing 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 Vibrating 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.

  • 7．Which model of barrel finishing machine should I choose?
  • You should choose which type of rotary barrel tumbling 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 rotary barrel tumbling 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 barrel finishing 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.

    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 finishing 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 barrel finishing machine machine use?
  • In China, it is generally 380V/3-phase/50Hz.
  • 12．What is the daily maintenance of the barrel finishing machine?
  • Routine maintenance of the barrel finishing 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.

  • 1．What is the tumbling deburring machine?
  • The tumbling deburring machine is also called a mass finishing machine, polishing tumbler. It uses mechanical methods to automatically and efficiently deburr and descale parts and products and workpieces in large quantities. It’s a machinery and equipment for surface treatment processes such as derusting, deflashing, cleaning, chamfering, degreasing, decontaminating, polishing, brightening. It works by combining the products that need polishing with abrasive media. Put it into the working barrel of the machine and let the abrasive and the workpiece tumble and rotate together, forcing the tumbling chip and the workpiece to collide and rub against each other to achieve the surface cutting effect.
    According to different operating modes, tumbling deburring machines are divided into the following four types:

    1.1 Vibrating deburring machine. It uses three-dimensional spiral vibration to drive the deburring media and the workpiece to move together to achieve the deburring effect.

    1.2 Centrifugal barrel deburring machine. Similar to the operation of a Ferris wheel, the motor drives the large centrifugal disk to rotate, causing the four barrels on the disk to rotate at high speed, driving the deburring media and the workpiece to move together to achieve the deburring effect.

    1.3 Centrifugal disc deburring machine. The chassis drives the barrel to rotate at a high speed on the horizontal plane, and the deburring media and workpieces also tumble and rotate in the barrel to achieve the deburring effect.

    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 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 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 tumbling 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: tumbling deburring media, tumbling porcelain media, high-density porcelain media, polyester media, white corundum finishing media, 3P precise finishing media, walnut shell mirror polishing media , corncob drying media,etc.
    Improper selection of abrasives during the finishing process will affect grinding efficiency and may even cause damage to the workpiece.

What is the centrifugal disc finishing machine?

Centrifugal Disc Finishing Machine

  • 1．What is the centrifugal disc finishing machine?
  • The centrifugal disc finishing machine is a barrel deburring and polishing finisher with the highest finishing efficiency. Its operating principle is to use a centrifugal rotating disk connected to a motor to drive the working barrel connected to it to rotate at a high speed, so that the ceramic media rotates at high speed together with the product workpiece, but a circle of PU lining tooth tip is specially poured on the inner wall of the barrel. Under the impact of the ceramic media and water flow, a feedback force in the opposite direction is generated, forcing the abrasive media and the workpiece to collide and rub against each other to achieve the surface cutting effect. This kind of grinding efficiency can be 10-30 times higher than other finishing machines, and you can get the surface finishing effect you need in a very short time.
    The barrel speed can reach 60-180 rpm, and the speed is controlled by the speed-regulating motor on the machine.

    ShineTec's centrifugal disc finishing machine
  • 2. What is the difference between centrifugal disc finishing machine and other finishing machine?
  • The main difference is that the finishing efficiency of the centrifugal disc finishing machine is the highest among all machines. Because the workpiece is always in a continuous cutting process in the abrasive media, this kind of polishing machine takes the shortest time and the fastest speed when finishing.
    When the machine is running, the probability of collision between workpieces is minimal because the workpiece and tumbling media are always moving in the same direction.
    Suitable for processing small to medium sized products. Because the diameter of the working bowl of this type of machine generally does not exceed 1 meter, and there is a column in the middle of the bowl, so workpieces exceeding 200mm cannot be placed. Even if it can be put into the machine at an angle, the workpiece will be stuck on the inner wall due to the high-speed rotation. If it is often stuck, it will break the PU lining and also cause the product to deform.
    The centrifugal disc finishing machine has the strongest cutting force, so it is suitable for finishing some parts and workpieces with long burrs, large flash, and relatively thick oxide scale.

    barrel ring of centrifugal disc finishing machine
  • 3．Can you tell me how a centrifugal disc finishing machine works?
  • 3.1 The working barrel of the centrifugal disc finishing machine is open, and the entire barrel can be turned over and tilted downward to facilitate loading and unloading of materials.

    3.2 Put the finishing media and product workpieces into the barrel together, turn the barrel over to straighten it, keep the mouth of the barrel upward, then add water and an appropriate amount of finishing liquid. The water surface should not cover the material for about 30mm, and only a small amount of chemical finishing liquid needs to be added. Generally, a 50L machine only needs to add about 30 ml. Note that the volume of materials in the barrel should not exceed 60% of the total volume of the barrel, and then the machine can be started.

    3.3 Turn the speed-regulating motor knob on the control panel to gradually adjust the barrel speed from low to high, and finally keep the barrel at the required speed. The entire finishing process is completed automatically, in the meantime, the operator can leave to handle other work tasks without having to stay at the machine.

    3.4 After the required finishing time is reached, adjust the speed of the barrel to keep the working barrel rotating slowly, add clean water to the top of the barrel to rinse, open the water flow valve at the bottom of the barrel, let the sewage inside flow out, and inject clean water above to complete the cleaning process.

    3.5 After cleaning is completed, turn the barrel over and pour out the workpiece and abrasive media. You can also configure a special vibrating separator to separate the abrasives and workpieces automatically, or it can manually screen and pick up the pieces to complete an finishing batch.

    unloading of centrifugal disc finisher
  • 4. What are the benefits of using a centrifugal disc finishing machine to polish parts?
  • Compared with manual polishing, there are definitely many advantages:

    4.1 Automatic deburring, deflashing, chamfering. Defects caused during workpiece processing that may cause harm to users can be automatically removed in large quantities.

    4.2 Automatically derusting and descaling. Surface problems such as turning lines and mold lines can also be removed.

    4.3 Automatic chamfering. Products can be chamfered quickly

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

    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 centrifugal disc finishing machine high?
  • Compared with manual finishing and polishing, the cost of rotary barrel tumbling 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 chemical finishing liquid is very small and the cost is almost negligible.
    A 50L centrifugal disc finisher can feed about 50 kilograms of product workpieces at a time. The grinding processing time for a batch is generally 30-60 minutes. The direct cost of grinding and polishing when evenly distributed to each product is minimal.
    On the other hand, in terms of saving labor costs, the advantages of using centrifugal disc finisher 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.

  • 6. What optional configurations are available for ShineTec’s centrifugal disc finishing machine?
  • 6.1 Wear-resistant bucket bottom gasket.

    6.2 Bucket electric tilt configuration.

    6.3 Quantitative automatic filling of clean water and polishing fluid.

    6.4 Built-in automatic separator.

  • 7．Which model of centrifugal disc finishing machine should I choose?
  • You should choose the model of centrifugal disc finishing machine based on the specifications and dimensions of your product parts.
    Generally speaking, if the length of your workpiece is less than 50mm, we recommend you use a 50L disc finisher; if the workpiece length is about 50-100mm, use a 120L finisher; if the workpiece length is about 100-150mm, use a 200L capacity machine. For workpieces exceeding 150mm, it is not recommended to use an centrifugal disc finishing machine.
    For this disc finishing machine, we also recommend that the mixing ratio of abrasive media to workpiece is about 3:1.

  • 8. What spare parts are available for centrifugal disc finishing machines?
  • The bottom plate of the centrifugal disc, the barrel ring, and the gasket between the barrel ring and the bottom plate are parts that need to be replaced frequently.
    Both the disc and the barrel ring have PU linings, which are prone to wear and tear during daily finishing. When the lining of these two parts is found to be damaged, spare parts need to be replaced immediately.
    Generally, the barrel ring needs to be replaced every 3-6 months. This mainly depends on the actual usage.
    After the gasket is worn, abrasive debris will get stuck in the gap between the barrel ring and the disc, causing the centrifuge disc to get stuck. It is also a key wearing part.

  • 9. How does ShineTec ensure the quality of the centrifugal disc finishing machine?
  • 9.1 Quality assurance of raw materials. Because the lining of the working barrel of the machine is PU, this lining 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 major domestic manufacturers and products from Dow Chemical of the United States, so the quality can be guaranteed.

    9.2 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.

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

    9.4 Steel plate profiles. Purchased from Shanghai Baosteel Products.

    9.5 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.

  • 10．How to order a centrifugal disc finishing machine?
  • Please confirm the following basic requirements first:

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

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

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

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

    10.5 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.

  • 11．What abrasive media can be used in centrifugal disc finishing machine?
  • Tumbling media for rough finishing, fine finishing and polishing:

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

    11.2 Finishing media 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.

    11.3 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.

  • 12．What kind of power supply does the centrifugal disc finishing machine use?
  • In China, it is generally 380V/3-phase/50Hz.
  • 13．What is the daily maintenance of the centrifugal disc finishing machine?
  • Like other finishing machines, routine maintenance of centrifugal disc finisher is crucial to extending the service life of the machine. Routine maintenance includes the following:

    13.1 Check the PU lining on the inner wall of the centrifuge barrel. Daily use of the machine will cause wear and tear on the PU lining in the barrel. You need to regularly check whether there are holes in the PU lining on the inner wall. Are there any defects in the ridges? If damaged, the barrel ring needs to be replaced.

    13.2 Before each start, check whether the water added to the barrel is too little or too much. The water surface is generally no more than 30mm above the material. Too little water will cause damage to the surface of the workpiece, the abrasive media will easily break, and the PU lining in the barrel will wear too fast. Too much water will cause the liquid to splash around when the barrel rotates at high speed, affecting the environment.

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

    13.4 Check for jamming of abrasive debris. The abrasives in the barrel will become smaller and smaller after long-term use. In addition, a lot of debris formed by workpieces and abrasives will be produced during the grinding process. If the width of these impurities is less than 1mm, they may get stuck between the barrel ring and the disc. The gap causes the machine to get stuck and unable to rotate. At this time, you need to shut down the machine, remove the barrel ring, clean the impurities, and restart the machine.

    13.5 Water temperature detection. If the centrifugal disc finishing machine runs continuously for more than 2 hours, the temperature inside the working barrel will become very high. Excessively high water temperature will speed up the aging of PU lining, so you need to cool down the temperature in the barrel by replacing the water.

  • 14．What industries can the centrifugal disc finishing machine be used in?
  • Centrifugal disc finisher 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.
  • 15．Are there any disadvantages to centrifugal disc finishing machine?
  • The processing capacity of the centrifugal disc finisher is less thanVibratory finisher and Tumbling barrel finisher. The processing volumes of commonly used models are generally 50L and 120L, so the amount loaded at one time is relatively small.
    Due to the small diameter of the barrel, workpieces with a length of more than 150mm are not suitable for finishing and polishing with this model, which may cause deformation and damage to the workpiece.
    Since there is a gasket between the working barrel ring and the disc, if the gasket is worn, a gap will appear, causing abrasive debris or impurities to get into the gap and jam the machine. If not dealt with in time, the motor may burn out.
  • 16．Does the centrifugal disc finishing 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.

What is the centrifugal barrel finishing machine?

About Centrifugal Barrel Finishing Machine

  • 1．What is the centrifugal barrel finishing machine?
  • Centrifugal barrel finishing machine, also called centrifugal disc finisher, is a type of high-efficiency tumbling and polishing machine. It operates like a Ferris wheel commonly found in parks. The four working barrels are installed on a wheel bracket that rotates radially around the center. As the bracket rotates, the barrels also perform radial centrifugal high-speed rotation. At the same time, the barrels also rotate. Therefore, there are two spin moves of the working barrels throughout the process.
    The working barrel is preloaded with product workpieces, tumbling media and water, the finishing compound liquid is filled with 60%-80% of the total volume. During the high-speed rotation of the barrel, the tumbling media and the workpiece collide and rub against each other, which plays a finishing and polishing role in deburring and descaling on the surface of the workpiece.
    Depending on the volume of the centrifugal working barrel, there are a variety of models to choose from, ranging from 30 liters to 300 liters, which can handle workpieces of different sizes.

    ShineTec's centrifugal barrel finishing machine

  • 2. What is the difference between centrifugal barrel finishing machine and other finishing machine?
  • 2.1 The centrifugal barrel finishing machine is a highly efficient grinding and polishing equipment. Because its operating speed is far faster than that of vibratory finishing and polishing machines and barrel tumbling finishing and polishing machines, the processing time of the same workpiece by the centrifugal barrel machine is generally within 30 minutes, while vibratory finisher may take several hours, and barrel tumbling finisher even takes ten a couple of hours. For centrifugal disc finisher, the processing time of a> is relatively close.

    2.2 The centrifugal barrel finishing machine is suitable for grinding and polishing some precision product parts with small dimensions and small surface burrs. Because the processing volume of the working barrel of commonly models is 7.5 liters to 20 liters, and the width of the barrel is about 280-450mm, products that exceed the length cannot be put into the barrel. Also, if the product is too heavy, it will have a great impact on the barrel wall during high-speed rotation, which can easily damage the PU lining, causing problems such as damage and shedding of the PU.

    2.3 Special molds can also be customized inside the working barrel to separate the inside of the barrel to form separate cavities. In this way, some larger workpieces can be ground and polished individually in independent cavities without fear of collision with each other.

    2.4 The centrifugal barrel finishing machine is also suitable for processing some product workpieces with complex irregular shapes. In addition, cross holes, dead corners, pipelines, and gaps in the workpiece can also be processed by using special abrasive media. Because the machine is rotating at high speed, the abrasive can reach these the holes on parts for polishing due to the centrifugal force. Of course, if the pores and pipelines are too long and too deep, there is nothing you can do, such as deep holes exceeding 200mm.

  • 3. How does ShineTec ensure the quality of centrifugal barrel finishing machine?

  • You must check the condition of the machine before each start-up to ensure that the machine is in good condition.
    Check whether the lining of the centrifuge barrel is damaged and whether the sealing cover is sealed and water-proof. Otherwise, the water in the barrel will be thrown out and splash inside the machine during the operation of the machine, causing safety hazards.
    Check whether there is any noise during the operation of the machine. These noises may be caused by damaged bearings, sprockets, transmission chains and other components. Check to see if they are properly lubricated.
    Check the machine’s transmission chain every two weeks. Is the tightness appropriate? Are the tightening bolts normal?

  • 10．What kind of power supply does the centrifugal barrel finishing machine use?
  • The applicable power supply for our universal centrifugal barrel finishing machine is 380V/3-phase/50Hz.
    If you need some special electrical specifications, such as 220V-480V, 50-60Hz, you need to confirm with us in advance. These specifications need to be customized.

  • 11. What equipment and materials are included in the polishing solution of the centrifugal barrel finishing machine?
  • The use of centrifugal barrel finishing machines to process workpieces includes three parts:

    11.1 Polishing machine. The centrifugal barrel finisher consists of a wheel frame, a centrifugal barrel, a motor, and some mechanical components and transmission components.

    11.2 Tumbling media. Choosing the right abrasive media is a key factor in achieving good grinding results for your workpiece in a centrifugal barrel machine. Including the shape, size, cutting force grade of the abrasive, and whether it will block the holes of the workpiece, these aspects need to be considered.

    11.3 Finishing compound liquid. The finishing fluid, water, abrasive media and workpiece are mixed and added to the barrel. The water needs to cover the material surface by about 30mm, and the total volume does not exceed 80% of the volume of the barrel. Only a small amount of finishing liquid is needed. Generally, for a 30L centrifugal finisher, only about 25ml of finishing fluid is poured into each barrel.

    11.4 Notes. After loading, check the sealing condition of the barrel. After tightening the sealing cover, each barrel must be placed horizontally on the ground to see if there is any water leakage. All four centrifuge barrel must be loaded into the machine before the machine can be operated. If you only need to load two barrels, put the barrels in diagonal positions to allow the wheel rack to keep the weight balanced. Be careful not to install only one barrel or three barrels, or the two barrels are not in diagonal positions. Otherwise, the roulette frame will be easily damaged when it rotates at high speed in an unbalanced state. Before starting the machine, gently turn the wheel frame by hand to see if there is any abnormal sound. Only when everything is normal you can start the machine. The grinding and polishing time of a machine lined with PU should not exceed 30 minutes at a time to avoid high temperature damage to the lining.

  • 2. How is a vibratory tumbler different from other mass finishing machines?
  • 2.1 The vibratory tumbler uses the eccentric excitation force generated by the vibration motor installed at the bottom of the working bowl to drive the tumbler media and workpiece in the bowl to perform a three-dimensional spiral tumbling motion. The abrasive media and the surface of the workpiece rub against each other to produce cutting effects. To achieve the purpose of finishing and polishing. The process is automated, batch-processed and easy to operate.

    2.2 The working bowl is open, you can see the real-time surface finishing effect of the product in the machine, and monitor the working status of the entire process at any time, such as the surface quality of the workpiece, The movement speed and direction of the tumbler media and the workpiece, the ratio of abrasive media, water and finishing compound liquid, etc.

    2.3 A simple automatic screening device can be installed inside the vibratory tumbler. After the finishing process is completed, the workpiece and the tumbler media can be automatically screened and separated, which greatly saves the labor intensity of workers’ manual pick-up and improves screening efficiency.

    2.4 The product models are rich, and the working capacity ranges from 30L to 3000L, including more than ten styles, to meet your finishing and polishing needs for parts and components of different sizes.

  • 3. Is there anything special about ShineTec vibratory tumbler when polishing?
  • Compared with other finishing and polishing methods on the market, vibratory tumbler have the following characteristics:

    3.1 Fully automatic, mechanized and large-volume. As long as the workpiece, abrasive media, water, and compound liquid are added to the machine, after starting the machine, workers can run to do other things, and the entire deburring and polishing process can be unattended.。

    3.2 It is suitable for automatic finishing and polishing of large quantities of parts with multiple specifications and complex shapes. For example, a machine with a capacity of 1000L can place 500 kilograms of workpieces at a time, and products of different sizes can be placed in the same batch. From a few millimeters to several meters, they can be processed in the same working bowl. Some parts of the product such as cross holes, dead corners, and gaps that cannot be processed by ordinary polishing equipment can also be used to meet the finishing and polishing needs by selecting appropriate tumbler media.

    3.3 Processing costs are low. The one-time purchase cost of the machine can range from several thousand to tens of thousands of dollars, and the tumbler media depend on the wear and tear. Because the abrasive media provided by ShineTec have high hardness and strong wear resistance, the wear of the products can reach less than 5%, so the using cost of consumables is extremely low. In addition, when the machine is running, only part of the labor is required when loading and unloading materials, and the labor cost is also very low. Compare with manual finishing and polishing or other process such as electrochemical polishing and other process methods are extremely advantageous.

    3.4 Environmentally friendly. The vibratory tumbler mainly uses abrasive media with cutting force such as corundum sand for deburring. It is a purely mechanical grinding process. The sludge generated can also be directly discharged through sedimentation, filtration, centrifugal separation, etc. A small amount of < a href="/product-category/chemical-compound/" target="_blank" rel="noopener">polishing fluid is also a neutral environmentally friendly solution, compare with chemical polishing with strong alkali solution, it can not be same.

  • 4. Is the running cost of a vibratory tumbler high?
  • The purchase cost of the machine can range from a few thousand dollars to tens of thousands dollars, and it can generally be used for more than a few years. The price of rough finishing media is also ranges from a few to more than ten dollars per kilogram. Generally, the machine can be used for more than a few years. It can also be used for several months to several years, and some polishing media like porcelain media, high-density porcelain media,etc. These tumbler media’s losses are smaller and can generally last for several years. Although stainless steel media are expensive to purchase at one time, they have almost no wear and can be used for a very long time.
  • 5．What is the price of a vibratory tumbler?
  • As can be seen from the above cost analysis, the price of buying a vibratory tumbler is not expensive. It can be said that if your product is suitable for using a vibratory finishing machnie for deburring, descaling and other processes, then you can believe that you have obtained extremely low finishing and polishing processing costs.
  • 6．What factors should you consider when purchasing a vibratory tumbler?
  • The first factor to consider is the working capacity of the machine, that is, the volume of the machine’s working bowl. So first, you need to confirm what the quantity or weight of the workpieces you need to process every day is? How much product do you need to finish per batch?
    There is a rough ratio between volume and processing capacity for your reference. Generally, for a working volume of 100 liters, the actual loading capacity is about 80%, that is, 80 liters, and the corresponding loading weight is about 80 kilograms, that is, the total weight of tumbler media + workpiece does not exceed 80 kilograms. Based on this ratio, based on your products need to be finished and polished, you can roughly estimate the volume of a vibratory tumbler.
    Another factor that needs to be considered is whether it is necessary to fine-finish and polish the surface brightness of the product after rough deburring, descaling and other operations? Because the tumbler media used for fine finishing are different from those used for rough finishing, if your product still needs fine finishing after rough finishing, you will need to replace the abrasive media in the machine. If the daily processing volume is relatively large, you will need to purchase two machines, one is used for rough finishing and the other is used for fine polishing.
  • 7. Can you tell me how a vibratory tumbler polishes?
  • First, you need to put the tumbler media and the workpiece into the machine, add an appropriate amount of clean water, the water surface should not cover the abrasive media, only need a layer of water at the bottom of the bowl, then add an appropriate amount of finishing liquid, generally a 100L machine only needs Just add about 100ml.
    After the machine is started, observe the tumbling and rotating direction of the abrasive and the workpiece in the working bowl. The normal grinding movement is that the abrasive media and the workpiece tumble from the outside to the inside of the bowl, and at the same time perform a clockwise rotation. These two movements in the machine are a constant cycle. If the direction is wrong, please adjust the angle between the eccentric weights at the upper and lower ends of the motor, or reverse the wiring positions of the two live wires of the three-phase power cord.
    After the finishing process is completed, rinse it with clean water while the machine is running, and then you can pick it up. Machines with a volume of less than 100L can manually pick up items directly from the machine, and those with a volume above 100L can use the machine’s built-in separator to automatically screen and pick out items.

  • 8. How long does it take for a vibratory tumbler to finish and polish?
  • The finishing and polishing time depends on the actual surface condition of the parts. There are two main factors that affect grinding time, one is the cutting force level of the tumbler media, and the other is the size of the machine. The tumbler media with heavy cutting has strong cutting force, the shorter the cutting time, and vice versa. The larger the working bowl volume of the machine, the greater the tumbling force of the abrasive and workpiece inside, the greater the cutting force, and the corresponding shorter time. Operations such as rough cutting, deburring, and descaling can take anywhere from a few minutes to a few hours, but fine finishing and polishing generally takes about 30 minutes per batch.
  • 9. Can I use the same vibratory tumbler for deburr and brighten?
  • Yes, as long as your workpieces is in time to deal with the quantity. But the tumbler media used in finishing and polishing are different, and the media need to be replaced each different process. This process is time-consuming, so it is recommended to prepare two vibrating tumblers at ordinary times, one for rough finishing and the other for fine finishing and polishing.
What is vibratory tub finishing machine?

About Vibratory Tub Finishing Machine

        Let me ask a question first: If you have some parts with a longer appearance, such as a length of more than 500mm, can our existing finishing machines be used? The answer is no. The length of the workpiece processed by the centrifugal barrel or disc polishing machine generally cannot exceed 300mm. Although the length of the barrel tumbling finishing machine can exceed 500mm, it is not suitable for polishing because of its low efficiency. Rapid finishing and polishing in large quantities and with high efficiency are not it’s features. Although the current vibratory bowl finishing machines are relatively versatile, they are unable to handle some workpieces that are too long, because the channel width inside the machine’s working bowl generally does not exceed 500mm. So if you want to polish and deburr this type of workpiece, you need to use a long-chamber vibratory finishing machine. The working chamber of this polishing equipment is a long rectangular tub. The length of the customized tub can reach 2-4 meters. It is a special polishing machine specially suitable for polishing extra-long parts.
The heavy-duty designed work tub can handle large product workpieces, but for some products that cannot collide with each other, such as large impellers, automobile aluminum alloy wheels, etc., some dividers can also be designed and installed inside the tub to form separate chamber, each product is finished and polished in an independent working chamber, without causing surface damage caused by collision of workpieces with each other.
This model is also very suitable for finishing and polishing some large products such as marble tiles, engine casings, and engine crankshafts.
ShineTec provides universal standard tub-shaped vibratory finishing machines, and can also customize models according to the length and width of your workpieces. The working volume can range from 15L to 3000L, making it the best equipment for finishing and polishing ultra-long and ultra-wide parts.

Frequently asked questions about rectangular tub finishing machines:

  • 1．What is vibratory tub finishing machine?

  • 2. Can you tell me how a vibratory tub finishing machine works?
  • The working principle of the vibratory tub finishing machine is similar with othervibratory bowl finishing machines . When machine working, you need to put the workpiece, abrasive media, appropriate amount of finishing liquid and water into the machine. After the machine is started, the abrasive media and the workpiece will roll together longitudinally. The abrasive media will rub on the surface of the workpiece, which can remove burrs and oxidation layer on the surface of the workpiece. The time of the entire grinding process is determined according to the condition of the workpiece surface. The longer the burr or the thicker the oxide scale, the longer it takes. After finishing is completed, you will get a batch of products with the same surface grinding effect.
  • 3．What device and abrasive media are required for the polishing process of ShineTec vibratory tub finishing machine?

  • 3.1 Tub finisher. The machine consists of a rectangular working tub, vibration motor, electrical control box and other mechanical accessories.
    Working chamber. The workpiece, tumbling media, finishing compound, and water are put into the tub together, and then a series of surface treatments are performed, such as deburring, descaling, degreasing, chamfering, cleaning, polishing and brightening. These operations can be completed in the same batch .The tub is also lined with wear-resistant PU glue to prevent the workpiece from being damaged by the machine and abrasive wear on the iron plate inside the tub body of the machine.
    Vibration motor. The vibration motor is installed at the bottom of the working tub or at both ends of the tub. If it is at the bottom, only one motor is needed. If it is installed at both ends, two identical motors are needed.
    Water and liquid filling system. The grinding liquid and water are pumped into the working tub by a pump. The finishing liquid can be used to soften the surface oxide layer and speed up the grinding efficiency. It also has the function of cleaning oil stains under the combined action of clean water.
    Electrical control box. You can use the switch to control the machine to adjust the tumbling speed and vibration frequency of the machine. It also has overcurrent and overvoltage protection to prevent the motor from overloading.

    3.2 Ceramic media. The ceramic media generally used for deburring is called a deburring media. It is the main material involved in the deburring process. Because of the different content and grit size of the corundum sand contained in it, the deburring media are divided into heavy cutting force, medium cutting force and light cutting force. By rubbing the surface of the workpiece, the burrs and scale are removed.

    3.3 Water. Water plays several roles in the vibratory finishing process. First of all, water can lubricate and buffer between the workpiece and the abrasive media, so that the surface of the workpiece will not be damaged by impact. In addition, it can also cool down the machine. If there is no water involved in the grinding process, just dry finishing will cause the work tub to be damaged. The temperature becomes very high, which can easily damage the PU lining, while also preventing dust pollution. Finally, it can also wash away abrasive debris, workpiece burrs, oxide scale and other impurities produced after finishing.

    3.4 Polishing liquid. Polishing liquid helps speed up the finishing and cutting process. It can also prevent metal product workpieces from being corroded after contact with water. After polishing with compound liquid, the surface of the product can become more shiny.

  • 5. What finishing and polishing processes can the vibratory tub finishing machine handle?
  • 5.1 Deburring. Burrs on the surface of product parts can be removed through the deburring process. We all know that burrs and flash can cause harm to users. After this process, the product becomes safe and easy to use.

    5.2 Smoothing and polishing. After smoothing and polishing process, the surface of the product will become brighter and the gloss will be further improved. If used with special polishing media and compound, the product will become dazzling and shiny. This is called brightening treatment.

    5.3 Degreasing and decontaminating. After the product is machined, a layer of sludge and dirt on the surface is difficult to clean. Ordinary manual cleaning is too inefficient and difficult to remove. The tub-shaped vibrating finishing machine can quickly clean the oil stains on the internal and external surfaces, dead corners, and holes in large quantities. It is the best automatic cleaning, degreasing and decontaminating process.

    5.4 Deflashing. Burrs, flashes are also annoying defects on the surface of workpieces. It is a quality problem that must be eliminated. A vibratory tub finisher can also achieve this purpose.

    5.5 Descaing. The tub polishing machine can also easily remove the oxide scale on the surface of the workpiece.

  • 6．What is the difference between the vibratory tub finishing machine and other finishing machines?
  • The first is that the length of the workpiece finished can be extremely long, such as more than 1 meter.
    Secondly, the working tub of the machine is open and unsealed. Compared with centrifugal polishers and barrel polishers, this structure allows users to observe the surface condition of the product at any time during the finishing process and evaluate whether it meets the predetermined standards.
    Furthermore, for some special large product components, such as aluminum alloy wheels, turbine blades, marble and other products that are not allowed to collide with each other, the working chamber can be separated and each product can be finished separately.
    It can be seen that the tub-shaped vibratory finisher is a finishing and polishing equipment with unique and specialized purposes.

  • 10. What are the power requirements for a vibratory deburring machine?
  • Required industrial power: 380V/3-phase/50Hz. If you want to use it on household power supply, you need to customize a 220/single-phase motor. Because the exciting force of civil electric motors is relatively small, the working volume of the machine does not exceed 100L.
  • 11. What deburring media are mainly used in vibratory deburring machines?
  • The effect of deburring depends on the selection of the correct and suitable deburring media. The higher the abrasive sand powder content and the larger the grit size, the cutting force will increase accordingly, but the wear resistance will decrease. The smaller the deburring media, the smoother surface after deburring will be better than the larger tumbling media.
    The types of deburring media are as follows:

    11.1 ceramic deburring media. There are different deburring strengths such as heavy cutting, medium cutting and light cutting. Heavy cutting tumbling media can grind and deburr workpieces made of harder materials, such as iron, titanium alloys, hard plastics, ceramic products, etc. Medium cutting and light cutting tumbling media can finish precision parts such as stainless steel and alloy steel.

    11.2 plastic media. Also called resin deburring media, also known as polyester media. Usually used for precision finishing, deburring and polishing workpieces. Especially suitable for soft metal workpieces, such as aluminum alloy, zinc alloy, copper, etc. If ceramic deburring media is used to deburring these materials, scratches, pitting, and color dissipation will occur.

    11.3 stainless steel media. Stainless steel media are mainly used to improve the gloss and brightness of metal workpiece surfaces. It can also be used to polish some fine burrs on the surface of certain plastic or ceramic products.

    11.4 Natural bio-degradable media. If you are looking for an abrasive media that has the ability to gently and slightly deburr, then plant-based organic abrasives like walnut shells, corn cobs, etc. are a good choice. This kind of abrasive media can simulate the polishing effect of a cloth wheel. Through long-term finishing under slight cutting force, the surface of the workpiece can achieve an effect close to mirror polishing, so many people also call it mirror polishing media.
    This kind of abrasive can also be used as a drying media for surface drying after grinding and polishing of products. It also has the function of absorbing oil stains on the surface of the workpiece. It is a safe and environmentally friendly bioabrasive.
  • 12. What routine maintenance can extend the service life of the vibratory deburring machine?
  • For example, is the vibration motor lubricated regularly every month? Check whether the PU lining of the working bowl is damaged? Is the discharge port filter blocked by sludge? Is the vibration spring on the base of the machine broken?

  • 13. How to choose the correct deburring media to match the vibratory deburring machine?
  • Tumbling deburring media selection plays a key role in the process of deburring. The abrasive sand in the tumbling media plays a role in finishing and polishing burrs on the workpiece.
    So how to choose the correct finishing media when deburring? There are currently four main categories of mass finishing media. Commonly used materials include brown corundum ceramic media, plastic deburring media, stainless steel polishing media and Natural bio-degradable abrasive media.
    These abrasive media have different cutting forces and different specifications and shapes, such as triangle, sphere, cylinder, three-star, cone, pyramid, wedge, etc.
    In order to fully reach the workpiece with complex shape during deburring, the upper shape can be made into a chamfered shape.
    Also consider whether the deburring media will clog holes and crevices in the workpiece. Generally, we will propose a selection plan for deburring machines and finishing media based on providing process samples testing.
    What are the best deburring machines and process solution and methods for deburring? Only after sufficient process testing and comprehensive consideration of surface effects and processing costs is the best solution.
