ABSTRACT:
A polishing apparatus is provided having a flat, stiffly elastic mounting plate for the workpieces. The workpieces are placed in contact with a rotating polishing plate but are kept from rotating along with it by a holder secured to the mounting plate. The flat face of the holder is spaced from the mounting plate. An annular ring is fixed in position between, and in contact with, the face of the holder and the mounting plate. As the workpieces are pressed against the polishing plate by a force transmitted through the holder, the ring, and the mounting plate, the mounting plate assumes a given curvature depending in part on the radius of the ring.
