Abstract
A polishing apparatus in which one of two workpieces to be polished or abraded which contact each other at respective arcuate or spherical surfaces, is placed on a fixed base and turned or fixed in a horizontal plane with the other workpiece held under pressure by a retainer provided on a gate type frame which can be swung around the center of curvature of the contact surfaces of the two workpieces 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 two pivot-connected block units vertically in a stepless manner and the position of the retainer to a reference axis can be varied. This enables the apparatus to be applied to workpieces having arbitrary curved surfaces to be polished and of different dimensions.
