Barrel Finishing Machine 【Patented】

【Features】
This machine was developed for finishing various kind of parts which are high precision,easily chipped-out or complicated shape.

  1. Easy to take container in and out.
    Cnotainer made of urethan
    Fitting with one bolt
  2. Compact design. No need a special tool for hoisting.
  3. Voltage:AC100V or AC200V
  4. Shorten processing time.
  5. Small footprint.
  6. No re-lining for a container is required(made by urethan)
  7. Easy to install-deinstall by one bolt fitting.
  8. 3 step-shift transmission and reverse mode are available.You can set programs up to 9 which could meet various works.


【3 dimensional relative movement】
     
The container are set and moved in a horizontal-leaning-revolution.
Within the container,works and polishing materials are in a status as if kneaded toward the center of container and the works are always staying within the polishing materials.
Advantages of staying works within the polishing materials.
1.Preventing traces by hitting of works
The polishing materials are working as a shock-absorber and preventing direct hitting of works. 

2.Prevent tangling, deforming or distortion
Because, the works are always staying within the polishing materials.

3.Significantly reduce processing time
Performance of polishing is better than conventional ones.


Conventional
 Conventional one has a horizontal rotation in which media, works and water can be rotated horizontally. The could give a separation between works and media.

 This would be a cause of hitting of works and remaining traces and / or abrasion marks. Such separation cannot give a well polishing and should require a longer processing time.


【Applicable a fragile works】

 To fragile works such as ceramics or ferrite, sequencer control can be applied which gives a stepwise changing of rotational speed. For example, initially lower speed and raising speed.
This prevented cracks.
