  • 3. What services can ShineTec provide for mass finishing machines?
  • The most important accessories of the mass finishing machine are the wear of the PU lining and the service life of the motor. Routine maintenance can ensure the service life of the motor is 5-10 years, or even longer. The PU lining in the machine will wear and tear, and its service life depends on the cutting strength and shape of the tumbling finishing media. Spherical finishing media will cause less wear on the PU colloid than sharp-angled media. Generally, the service life of PU lining of centrifugal disc finisher is 3-6 months, while that of vibrating polishing machine can reach more than 10 years. Of course, this mainly depends on the cutting force and shape of the polishing media. We provide a one-year warranty for the entire machine.

  • 5．Which mass finishing machine is suitable for my product?
  • You may be confused when choosing to use an mass finishing machine, which model should I choose? vibratory finishing machine and tumbling barrel finishing machine are the two most widely used machines. If you are looking for a machine with faster finishing speed, you should choose a vibratory finisher. If you are pursuing better surface quality and can accept a relatively long finishing and polishing time, a barrel tumbling polishing machine is the best choice. Regarding vibrating finishing machines, you can also choose machines with built-in dividers, as this allows you to process different workpieces in the same time. If a large number of parts are being processed and can be mixed together for polishing or cleaning, then vibratory finishing machine with separator is the best choice because it can meet the requirements of automatically separating workpieces and abrasive media without the need to manually screen each piece. If your product is a special-shaped long part, then rectangular tub finishing machine is the right choice. The tub-shaped vibratory finisher is also suitable for polishing large marble for home decoration. Dividers can also be installed inside to avoid damage caused by products hitting each other during the finishing process. If you want to use automatic conveying function when loading workpieces, then the continuous flow vibratory finishing system can meet your needs. This kind of machine can also control the time of a polishing cycle of the product. Commonly used products suitable for this type of machine can be powder metallurgy parts, die castings or stamping parts. If your product is a high-value precision component, use centrifugal barrel finishing machine. The processing time of this type of machine is very fast, such as dental implant polishing, 3D printed parts deburring, surface polishing, textile accessories polishing, etc. This machine can be used. If polishing small and medium-sized workpieces, centrifugal disc finishing machine is a good choice.

  • 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. You can read the accompanying operation manual and follow the step-by-step installation instructions. The dosage of tumbling media, product workpieces, and polishing compound requires a suitable ratio. Once you've done that, just start the machine.
  • 13．What fields can the mass finishing machine be used in?
  • ShineTec's mass finishing machines are suitable for products made of the following materials: Wood, rubber, metal, alloy, glass, steel, stone, or others. It also supports the following products in the manufacturing process: Laser cutting parts, 3D printing parts, die casting parts, stamping parts, relief parts, etc.

  • The general adapter power supply for the machine is 50Hz/380V/3-phase. For overseas markets, we also provide 60Hz, 220V, 460V, 480 and other applicable voltages.
  • 15．How long does mass finishing usually take?
  • Polishing time varies depending on the machine model. It can range from 10 minutes to several hours depending on the workpiece being processed. Generally speaking, the efficiency of centrifugal disc finisher > centrifugal barrel finisher > vibratory finisher > barrel tumbling finisher.
  • 16. What is the function of the polishing liquid added in mass finishing?
  • Polishing compound play an important role in the polishing process. 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.
