ABSTRACT:
An improved barrel polishing process is disclosed in which pieces or parts mounted in a rotary barrel on spindles carried by the head thereof are passed through the abrasive layer formed in the barrel. The pieces are forced to turn around a vertical shaft while turning on their own axis so that they pass alternately through a denser portion of the abrasive layer and through a coarser portion. This ensures a uniform finishing of the pieces.
