ABSTRACT:
A method and apparatus for finishing parts is disclosed. The apparatus includes a pair of concentric circular members of different radii having a horizontal axis resiliently mounted to a base for orbital vibration. Parts and a finishing media are introduced into a closed annular chamber defined by the area between the circular members. Orbital vibration causes the parts and media to move in a helical path having a substantially vertical plane around the inner member to a discharge opening. At the discharge opening the parts are separated from the media, which is then classified and portions thereof are returned to the chamber. A motor driven eccentric shaft mounted co-axially of the circular members produces the orbital motion.
