Abstract: A part processing apparatus includes a plurality of part mounting devices, each of which is rotatable. Parts are mounted on the plurality of part mounting devices, and the parts are rotated on the devices during a part processing operation. A rotational input shaft is coupled to all of the plurality of part mounting devices so that all of the part mounting devices rotate together. A part processing robot may be movable between a plurality of positions located adjacent each of the part mounting devices. Alternatively, the part mounting devices may be movable to a plurality of different positions so that each of the part mounting devices can be located adjacent to the part processing robot.
