ABSTRACT:
A finishing method and apparatus wherein a tub containing loose abrasive material is rotated at high speeds about a vertical axis to cause finishing media to form a layer of media along the side wall of the tube. One or more workpieces to be finished are supported in the media and are rotated about a vertical axis coincident or parallel to the axis of the tub such that a rapid cutting and finishing action is provided by the relative movement of the tub and the workpieces. The method and apparatus further comprises removing compound continuously from the lower part of the tub and cooling the material and returning it to the tub.
