  • 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. Electrical control parts come from regular manufacturers such as Delixi or Chint. 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.

  • 9．What problems can occur when using a vibratory polishing machine?
  • 9.1 The tumbling direction is wrong. The normal rolling direction of polishing media and workpiece is from the outside of the working bowl to the center. If the direction is opposite, please observe whether the angle between the upper and lower eccentric weights of the motor is 90 degrees. If the angle is correct, the problem may lie in the order in which the three-phase power lines are connected. Please exchange the positions of the U and V lines.
    9.2 The rotation direction is wrong. The normal rotation direction of the polishing media and workpiece in bowl is clockwise. If it is not correct, please try to adjust the angle of the upper and lower eccentric weights of the motor to 75 degrees. You can also reduce the weight of the eccentric block at the bottom of the motor or increase the weight of the eccentric block at the top of the motor.

  • 12. What are the spare parts and auxiliary materials that make up a vibratory polishing machine?
  • The most important components are as follows:
    12.1 The working bowl of the machine. The shape is arc-shaped or U-shaped bowl-shaped body. The polishing media, workpieces to be processed, water and polishing liquid are placed in the bowl. The inside is lined with wear-resistant PU colloid, which can protect the workpiece from directly hitting the inner wall of the bowl and the polishing media from cutting the inner wall iron plate.
    12.2 Separating screen. The separating screen is mainly used to separate the workpiece from the abrasive media after polishing. Built into the working bowl of machines over 100L, it is also cast from wear-resistant PU glue, with round or square holes. The diameter is generally above 20MM. If the hole size needs to be very small, we can also customize a screen plate made of stainless steel plates for you. The screen plate can be changed at will to adapt to different workpieces and polishing media.
    12.3 Vibration motor. This is the main component of the vibratory polishing machine. The machine operates by the excitation force it generates. It is also a key factor that determines the working efficiency and operating life of the machine.
    12.4 Suspension spring. The working bowl is supported by springs and vibrates up and down. The hardness and length of the spring also affect the vibration amplitude of the machine.
    12.5 Water recovery device. This is an optional device. Water and polishing fluid can be recycled, reducing sewage discharge and meeting environmental protection requirements.
    12.6 Frequency converter. The vibration amplitude and operating speed of the machine can be controlled through the frequency converter. Some workpieces are easily deformed or fragile, and the vibration amplitude of the machine needs to be reduced or the running speed of workpieces made of different materials needs to be adjusted, which can be adjusted through it.
    12.7 Acoustic lid. The acoustic lid can reduce the noise produced by the machine when it is running. Generally it can be reduced by about 20 dB.
    12.8 Control box. The vibrating polishing machine can be equipped with an external electrical control box. It can be mechanical button type or digital display touch screen type.
    12.9 Polishing media. There are many types of abrasive media. There are tumbling polishing media made of brown corundum, porcelain, and resin, as well as stainless steel and abrasive chip from wood and bamboo chips. Each material has different shapes and sizes to adapt to various irregular shaped workpieces.
    12.10 Polishing liquid. The compound liquid added to the abrasive and workpiece play a supporting role in the finishing and polishing process. Generally, finishing liquid improves the cutting efficiency of the workpiece, polishing liquid can improve the brightness of the workpiece surface during fine finishing, and anti-rust liquid is used to protect the surface of metal workpieces from corrosion and rust after being cleaned with water. It comes in liquid, powder, and paste forms. It can also be used without adding water for dry finishing.
