polishing disc for a tool for fine processing optically acting surfaces of eyeglass lenses, tool for fine surface processing

摘要

The invention relates to a polishing disc for a tool for fine processing optically acting surfaces of spectacle lenses having a base body (14) having a central axis (m) to which a layer is attached. softer intermediate (16) relative to the base body (14), made of an elastic material, on which a support of the polishing means (18) is seated. the intermediate layer has at least two areas (20, 22) of different hardness which are arranged one after the other in the direction of the central axis of the base body. In this case, the area of the intermediate layer adjacent to the base body is softer than the area of the intermediate layer upon which the polishing medium support is seated. The simply constructed polishing disc thus can cover a large area of curvature of the spectacle lens, which in particular enables high productivity in recipe preparation.
