5. Additional instructions
  • Because stainless steel metal sheet processing parts are easily deformed, a centrifugal finishing machine with a small-capacity working barrel is used to reduce the operating speed and use it with softer texture cone-shaped resin media (also called plastic media) is used to chamfer and deburr. If you use ceramic tumbling media or other very hard abrasive media will cause problems such as deformation and bending of the workpiece, and ceramic deburring media can easily contaminate the stainless steel surface and make the surface black.
  • So why don’t polish parts use vibratory polishers? Because the vibrating polishing machine will cause the thin parts to stick to each other, and multiple pieces will fit together, which will not achieve the finishing and polishing effect.
  • Products can be separated automatically using a vibrating separator, to control the vibration amplitude of the vibrating separator so that no bending deformation occurs due to mutual collision.
  • In order to improve the anti-rust and anti-corrosion performance of the product after water cleaning, vibrating dryer, with corn cob polishing media, dry the moisture and wipe away water stains on the surface of the product.

6. Final summary
  • In this case, we demonstrate a process for surface chamfering and deburring of stainless steel laser-cut metal sheet parts using resin finishing media and corn cob drying media.
  • This process is also suitable for surface polishing of sheet metal parts such as carbon steel and aluminum alloys.

5. Additional instructions
  • Because the workpiece material is relatively soft, resin media can only be used to roughly remove scale and burrs. If you use ceramic deburring media, so the hardness is too high and the sand grits are too coarse, it will wear the surface of the product and cause scratches, pitting, color contamination and other problems.
  • Also because of the material, if a machine is used for automatic separating, the collision of workpieces will cause surface damage.
  • Zinc alloys can easily re-oxidize when exposed to water and air. Therefore, we need to dry the water immediately after polishing.

6. Final summary
  • In this case, we demonstrate a process of using a resin (plastic) finishing media to deburr, remove scale and brighten on the surface of a zinc alloy handle.
  • This process is also suitable for polishing belt buckles, jewelry pendants, souvenirs, craft gifts and other products produced from aluminum alloy and copper die-casting parts.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  • 13. What is the size of ShineTec’s resin media?
  • ShineTec can provide cone and tetrahedral resin media up to 100mm. Minimum size is 6mm pyramid and cannonball shaped resin media.
    We can customize special sizes according to the shape and size of your product parts.

What is vibratory deburring machine?

About Vibratory Deburring Machine

  • 1. What can the ShineTec’s vibratory deburring machine do?
  • Because the machine uses the spiral three-dimensional vibration deburring and polishing principle, it is called a vibrating deburring machine.
    This is the most commonly tumbling deburring equipment. It can be used to automatically and efficiently remove burrs, scale, flash, mold lines, turning lines, rust, oil on surface of parts and workpieces in large quantities. It’s good at surface finishing treatments such as smoothing, chamfering, cleaning, polishing, brightening and increasing the surface strength of the workpiece.
    The machine uses tumbling, rotating, and vibrating methods to complete the finishing and deburring of the workpiece in a controlled manner. The ceramic deburring media with cutting force interacts with the parts under the action of excitation force, the surfaces of the workpieces and media rub together to remove burrs or oxide layers.

    ShineTec's automatic vibratory deburring machine

  • 2. What equipment or materials are used to complete the vibratory deburring process?
  • The vibratory deburring process is mainly completed by the following equipment and materials:

    2.1 Vibrating deburring machine.
    The vibrating deburring machine is mainly composed of a vibration motor, a vibration working bowl, springs, and an electrical control box. These components are combined to achieve automatic deburring.

    2.2 Water.
    Vibrating deburring mainly uses wet finishing, so an appropriate amount of water needs to be used during the grinding process. It can buffer the collision between the deburring media and the workpiece, and can also clean the sludge on the surface of the workpiece. It is an indispensable part of the grinding process.

    2.3 Tumbling deburring media.
    The deburring media and workpiece are mixed together and put into the working bowl of the vibratory deburring machine. The deburring media contains corundum sand with cutting force, which can deburr the surface of product parts. The intensity of deburring depends on the content of corundum sand contained in the deburring media.

    2.4 Chemical deburring liquid.
    deburring liquid is also poured together with the media and workpiece in the work bowl. There are different types of deburring compound, such as liquid and paste, and some also have anti-corrosion and anti-rust effects.

  • 3.Can you tell me how the ShineTec vibratory deburring machine deburrs?
  • The vibratory deburring machine has a circular bowl-shaped working chamber for loadingceramic media and product workpieces. The working bowl is lined with wear-resistant PU glue, and a vibrating motor is installed inside the machine. The lower part of the bowl is suspended and supported by a circle of springs.
    First, the ceramic deburring media needs to be added into the bowl together with the workpiece, deburring fluid, and water. After the machine is started, the motor drives the working bowl to produce a three-dimensional spiral motion. The deburring media in the machine rotates and rolls in the bowl and rubs against the surface of the workpiece, so that the burrs on the surface of the part can be cut away.
    The movement of the deburring media in the working bowl is continuous and reciprocating, so that the surface of the workpiece can be deburred, cleaned and polished.

    After the deburring process is added to the product, the surface quality will be greatly improved, and the return rate of your product workpieces will be greatly reduced.
    Deburring and cleaning the product before painting or painting can improve the adhesion of the paint layer and improve the overall aesthetics of the product.
    After being processed by a vibrating deburring machine, the strength of the product surface can also be increased, improving the quality and service life of the workpiece.
    In short, the vibratory deburring machine can be applied to various metal or non-metallic product parts, and is also suitable for irregular and complex-shaped special-shaped workpieces. It is a multi-purpose finishing and polishing artifact.
  • 6.What are the typical application fields of vibratory deburring machines?
  • Most products in machining, casting and forging, injection metallurgy, mold manufacturing and other industries require deburring during the manufacturing process. The product material may be plastic, metal, wood, alloy, etc. Use ShineTec vibrating deburring machine, with the correct selection of deburring media, finishing compound and appropriate amount of water, it is very simple, you can expect a satisfactory surface treatment.
    The control of deburring time is also a factor that affects the grinding effect. The same machine can achieve different purposes with abrasive media of different materials and shapes and finishing liquid of different uses, such as deburring, descaling, chamfering, rounding, deflashing, smoothing and other requirements.

  • 7. Can the vibratory deburring machine be used at home?
  • Our vibratory deburring machine is suitable for use with 3-phase/380V industrial power supply and is therefore not suitable for home use. Household use requires an additional customized 220V/single-phase motor, which is costly and uneconomical.
  • 8. Are there any differences in the size of the workpieces that the vibratory deburring machine can be used to deburr?
  • Our deburring machines are suitable for processing various types of workpiece with different specifications and complex shapes. The dimensional accuracy of the product will not be affected after processing.
  • 9. How many workpieces can a vibratory deburring machine process at one time?
  • The number of workpieces that a vibratory deburring machine can process at one time depends on the volume of the machine’s working bowl. ShineTec can provide machines with different volumes from 30L to 1200L.
    It also depends on the size of the workpiece. The smaller the workpiece, the greater the quantity that can be processed at one time.

  • 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.

  • 2. How to choose the right vibratory polishing machine?
  • In response to your workpiece polishing needs, we will ask you to send samples for process testing in the early stage. If you are satisfied with the final results of our samples, we will then based on the actual conditions of your products, such as material, shape, size, and processing quantity. and other factors, provide a professional process solution, select vibratory polishing machines with different processing capacities, or corresponding auxiliary equipment that can help improve efficiency, complete supporting functions, and polishing media that suit the requirements.
  • 3.How do you determine the processing capacity of the vibratory polishing machine you need?
  • Based on the sample results of your workpiece, the process selection for polishing treatment is determined. Next, you need to provide the daily processing quantity requirements of your workpieces. The workpiece and polishing media cannot fill the entire machine. Generally speaking, the total volume of polishing media and workpiece cannot exceed 80% of the machine capacity. The following is a reference table for the volume ratio of media to workpieces corresponding to different polishing process requirements during feeding:
    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.
  • 4. What is the quality guarantee for the parts and raw materials of the vibratory polishing machines from ShineTec?
  • We purchase reliable spare parts from big brands to produce our vibrating polishing machines. The following are the purchasing channels for spare parts:
    The vibration motors come from large professional manufacturers in Wuxi or Shanghai.
    The PU lining rubber comes from Dow Chemical of the United States.

    The brown corundum sand powder used in the production of ceramic media is also a new top-level raw material and is not a secondary recycled material used by many small manufacturers in the industry.
    Micropowder and clay are also sourced from top domestic manufacturers.
    Therefore, the main parts and raw materials required for production are traceable, and quality can be guaranteed.
  • 5.What does the guide angle of the eccentric weight on the motor mean?
  • The angle formed by the eccentric weights (commonly known as hammers) at the upper and lower ends of the motor is called the guide angle. The factory default angle is 90 degrees at right angles to each other. This angle causes the polishing media and workpiece to tumble from the outside to the inside of the vibrating polishing machine and rotate clockwise. If you need to adjust the vibration and rotation directions, the two included angles can be adjusted to 70 degrees or 120 degrees.
    The adjustment of eccentric weight of the vibration motor has two functions:
    ⑴ Adjustment of the excitation force: Remove the tightening bolts of the eccentric weight and adjust the excitation force by increasing or decreasing the number of eccentric weights;
    ⑵ Adjustment of the angle between the upper and lower eccentric weights: the upper eccentric weight is a fixed block and the lower eccentric weight is an adjustable block, both of which are pressed on the motor shaft using fastening bolts. There are reference lines engraved on both ends of the rotating shaft. The outer surface of the lower weight is equipped with a scale indicating the rotation angle. Loosen the pressing bolt of the lower eccentric weight and rotate the lower eccentric weight so that the angle scale mark on the lower eccentric weight is aligned with the reference mark of the rotating shaft line, adjust to the required angle, and tighten the lower eccentric weight holding bolt; if you need to adjust the angle of the upper eccentric block, you can also adjust it according to the corresponding method.

  • 2. What are the types of vibratory finishing machines?
  • ShineTec provides various types of vibratory finishing machines, which correspond to different product polishing needs.

    U-shaped vibratory finishing machine without separator.

    U-shaped vibratory finishing machine, the shape of the working bowl is a design similar to the letter “U”, and the inner wall of the upper opening of the bowl is straight, so it is also called a straight-wall vibratory finishing machine. Because there is no discharge separating screen, the size of the machine can be made smaller, and the minimum capacity can start from 30L. However, after the workpiece is polished, it needs to be picked up manually or mixed with abrasives media and discharged from the machine discharge port.

    U-shaped vibratory finishing machine with separator .

    There is a discharge port separator installed inside the working bowl of the machine that can automatically screen workpieces and tumbling media, so the minimum capacity of the machine needs to be from 100L. After the polishing task is completed, the workpieces can be automatically screened and output from the separating port. There is no need to manually grab each piece from the machine, which greatly improves the separation efficiency of the workpieces and abrasive media after batch polishing and reduces the time required and intensity of work.

    Arc-shaped vibratory finishing machine without separator.

    The arc-shaped vibrating finishing machine is also called a curved wall finishing machine because the inner wall of the working bowl is a curved arc design. Such a structure will generate greater pressure during the finishing and polishing process, which can improve the finishing efficiency of the machine in a relatively short period of time. It is especially suitable for products that require spherical tumbling media for bright polishing.

    Arc-shaped vibratory finishing machine with separator.

    Like the U-shaped machine, its working towl is equipped with a discharge port separating device that can automatically separate the workpiece and the tumbling media. Improve the screening efficiency of workpieces and reduce labor intensity.

    Tub-shaped linear vibratory finishing machine.

    It is suitable for surface finishing and polishing of large or extra-long parts. The vibration deviation generated by the vibration motor is used to cause the workpiece and the tumbling media to produce a two-dimensional movement trajectory, so that the workpiece and the finishing media grind each other in the working bowl. Achieve surface gloss effect.

    ❖ Continuous orbital vibratory finishing machine.

    By installing a spiral tunnel structure in the working bowl of the machine, a one-way motion trajectory is achieved for the workpiece to enter from the feed port and exit from the discharge port during the polishing process.
    The polishing time of a single workpiece can be controlled to avoid collision between workpieces.

    ShineTec's continuous tunnel bowl vibratory finisher

    ❖Vibrating dryer.

    Same as the vibrating finishing machine, the excitation force is generated by the vibration motor, which drives the drying media and the workpiece in the working bowl to produce a spiral three-dimensional movement. The media and the workpiece rub against each other, thereby achieving the effect of dehydration and drying of the workpiece. A hot air circulation device can also be installed to speed up the drying process.
    All vibrating finishing machines can be equipped with cylinder flaps for separator and silencer cover accessories to improve work efficiency and reduce work noise.

  • 3. How to choose a suitable vibratory finishing machine?

  • 8. What are the common problems in the operation of vibratory finishing machines?
  • Generally you will encounter two problems during the operation of the machine. One is that the tumbling direction of the materials is wrong; the other is that the rotation direction of the abrasive media is wrong.
    If the operation is normal, the tumbling direction of the abrasive and workpiece is from the outside of the working bowl to the central cylinder. The material rotates in a clockwise direction.
    If you find that the rolling direction is wrong, first check whether the two eccentric weights on the bottom of vibration motor are at an angle of 90 degrees to each other. If not, please adjust the angle of the eccentric weights.
    If the problem still cannot be solved after adjusting the angle of the eccentric weight, please check the power cord of the control box and exchange the live wire and neutral wire in the three-phase line.
    If the abrasive media movement direction in the machine is not clockwise, first check whether the abrasive load is too much. Please confirm that the ratio of abrasive to the total volume of the working bowl does not exceed 2/3. Also check again that the angle between the motor eccentric weights is 75 degrees or 120 degrees.
  • 9. What kind of power supply does a vibratory finishing machine require?
  • Our vibratory finishing machine requires 3 phases, 380V, 50Hz. If there are different power usage environments, please confirm with us in advance before ordering the machine.
  • 10. What components does the vibratory finishing machine include?
  • Different models contain different parts. A complete set of machines generally includes the following components:

    10.1 Work bowl.
    The working bowl is a container used to hold the finishing media and the workpiece for mixing and tumbling. According to the processing capacity of the machine, the volume of the bowl is also different. The inner wall of the bowl is lined with high-strength wear-resistant elastomer polyurethane (PU) to protect your polished parts and prevent wear of the inner wall of the machine.

    10.2 Separating screen.
    There are two types of built-in separating screens. One is made of PU casting and is suitable for screening workpieces of regular sizes. The other is made of stainless steel mesh, which is suitable for relatively small product parts.

    10.3 Vibrating motor.
    The vibrating motor is the power source of the vibratory finishing machine and is also a very important machine component. The motor with the eccentric weight generates excitation force, which drives the abrasive media and the workpiece in the machine working bowl to produce spiral three-dimensional motion to achieve surface finishing effects such as deburring, descaling, chamfering, contaminating and derusting and brightening .

    10.4 Spring.
    A ring of spring supports at the bottom of the working bowl suspends the bowl body on the base. The motor drives the working bowl to produce up and down reciprocating vibrations.

    10.5 Acoustic Lid.
    The machine can also be equipped with an optional acoustic lid to reduce noise during operation. However, this is not a necessary accessory, because the noise generated by the vibrating finishing machine during operation is bearable for the human body.
    In addition, the acoustic lid can also prevent the foam produced by adding excessive polishing liquid from splashing and staining the surrounding ground environment.

  • 10.What are the different types of mass finishing machine?
  • There are four different basic types of mass finishing polishers. They are vibratory (also called vibrating) finishing machines, centrifugal disc finishing machines, centrifugal barrel finishing machines, and barrel tumbling finishing machines.
    In these models, the machine drives the workpiece to tumble and rotate together with the abrasive media, and the abrasive frictionally cuts on the surface of the workpiece to achieve the purpose of polishing. This process is also called mass finishing.
    Vibratory finishing is the most commonly used polishing method. Driven by the excitation force of the motor, the abrasive and the workpiece perform a three-dimensional spiral tumbling motion in the machine. The surface of the workpiece is cut by the finishing media to complete the polishing process.
  • 11.Are there different types of abrasive media?
  • Yes, there are different types of tumbling finishing media suitable for different process requirements.
    The specific parts are different, and the applicable abrasives media are also different.
    Tumbling media include ceramic media, plastic/resin media, stainless steel media, bio-degradable media and other varieties.
    Each abrasive media has different shapes, specifications, cutting forces and other indicators.
    You can choose different tumbling media according to your different needs.
  • 12.How to use this mass finishing machine?
  • Our machines are easy to operate and use.

    It can help soften the surface of the workpiece, clean oil stains during friction cutting, protect the product surface, prevent surface oxidation, reduce roughness, and improve brightness.
  • 17.What are the best finishing media for mass finishing machine?
  • Different workpieces and machine models are suitable for different finishing media. So there is no such thing as the best abrasive.
    Of course, the quality of the abrasive media will definitely differ. High-quality tumbling media are definitely better than low-quality and low-priced ones.
    Inferior tumbling media will damage the surface of your workpiece and increase your polishing time.
    Poor tumbling finishing media are produced from recycled corundum sand, which has poor wear resistance and high wear. The sludge generated in the same processing time will greatly increase, and the product service life is short. Although the initial purchase price is cheap, it is not durable and increases the use of the media and sludge disposal costs.
    Commonly used abrasive media with cutting force include ceramic deburring media and resin media.

    17.1 Ceramic media.
    Ceramic media are used for deburring and finishing hard parts.
    According to different cutting forces, they can be divided into different product types.
    The tumbling media with cutting force is generally ceramic finishing media, polishing and brightening is porcelain polishing media.

    17.2 Resin media.
    Resin media is also called plastic media, polyester media, suitable for deburring and finishing of soft metal or alloy products.
    For example, workpieces made of aluminum alloy, magnesium alloy and other materials.
  • 18. What should I pay attention to when operating the mass finisher?
  • Routine maintenance of the machine is crucial to its service life.
    Generally, the following steps should be checked regularly to ensure that the machine is operating normally.

    18.1 Amount of tumbling media used.
    The proper abrasive media must always be kept in the machine. The volume of the tumbling media in the machine is generally more than 2/3 of the overall capacity of the working chamber. Do not put a small amount of tumbling finishing media in the machine just to save costs.
    Too little finishing media will damage the workpiece, slow down the grinding process, and reduce polishing efficiency.

    18.2 Check the drain outlet regularly.
    Debris or sludge from the finishing process can sometimes clog drains. Therefore, it is necessary to regularly check whether the drainage outlet is open or not.
    If it is blocked and not dealt with in time, the machine will be flooded with water.

    18.3 Inspection of PU lining.
    The PU lining protects the workpiece and prevents the finishing media from directly contacting the inner wall of the chamber and cutting the machine working chamber.
    Therefore you should always check the wear of the PU lining rubber. Once damaged, the machine should be re-lined promptly.

    18.4 Do not use the machine under overload conditions.
    Loading excessive workpieces into the machine can damage the machine. At the same time, self-damage of workpieces is caused by the collision between workpieces.
    Therefore, it is necessary to read the manual carefully and understand the maximum working load before starting to use the new machine.
