Abstract
A honing, lapping or polishing machine includes a central inner gear member and an outer annular gear member each having an annular row of teeth, and a plurality of workpiece holder discs having teeth at their outer peripheries in driving engagement with the teeth on the inner and outer gear members in a planetary gear type fashion. The workpiece holder discs have recesses for receiving workpieces. The number of teeth on the outer gear member is an integral multiple of the number of teeth on each workpiece holder disc. A drive assembly rotates the inner gear member and is arranged to stop the workpiece holder discs in a predetermined loading and unloading position of at least one of the discs in response to a position signal from a detector assembly. The detector assembly includes a position detector movable into the path of the discs to provide the position signal when one of the discs reaches a predetermined relative position with respect to the position detector.
