CURVED SURFACE RUBBING APPARATUS

摘要

A polishing apparatus, in which one of the two members which contact each other movably at their respective arcuate or spherical surfaces is placed on a fixed base and turned or fixed in a horizontal plane with the other member held under pressure by the retainer provided on a gate type frame which is adapted to be swung around the center of curvature of the contact surfaces of the two members by a swinging unit capable of varying the range of swinging movement of the gate type frame. The center of the swinging movement of this frame can be varied by changing the position of the two pivot-connected block units vertically in a stepless manner. This enables the apparatus according to the present invention to be applied to a device having an arbitrary curved surface to be polished.
