|| This is a machine that abrades matters
in its bowl by oscillating them in 3-dimensinal and spiraling
movements, using a specially designed oscillating motor.
Parts and abrading stones revolve and rotate in the
bowl, and the parts get polished without being damaged
This machine is used for butt removal, R-shape processing,
softer friction, pre-coating grinding, and etc.
The abrader can be used as a unit like an oscillating
or magnetic concentrating machine.
