Honing, lapping and polishing machine in which an outer ring having pins or teeth and a central inner ring driven in a rotary manner by a drive motor and having pins or teeth are arranged at the working level of the top and bottom working disc, and work-holding discs are arranged between the working discs, in which arrangement the work-holding discs, like planetary gearing, can be brought as planet gears having a spur tooth system into rolling engagement with the pins or teeth of outer and inner ring and have location openings for the workpieces, and in which the drive motor has a control circuit as well as a brake, the drive motor being switched off and the brake being switched on when the control circuit transmits a corresponding stop signal, the pins or tooth number of the outer ring being an integral multiple of the pins or tooth number of the holding disc. A position sensor is provided outside the revolving path of the holding discs, which position sensor produces a position signal when a working disc assumes a predetermined position relative to the sensor, and the control circuit produces the stop signal when it receives the position signal. �<IMAGE>� |
