Abstract:

This paper presents the results of a study of the optical surface quality of items processed using three types of polyurethane at the polishing stage by means of multi-workpiece processing. These are compared with the results of processing the optical surfaces of items by the standard technology (on resin). This type of polishing wheels is shown to be effective for achieving the lowest roughness, the minimum deviation of the shape of the surface profile, and the minimum local error of the surface shape. The use of polyurethanes makes it possible to obtain items processed on a block with small scatter in the PV and RMS parameters and increases the percentage yield of finished items with respect to optical purity.
