Polishing disc for a tool for fine processing of optically active surfaces of in particular spectacle lenses and method for its production

摘要

A polishing plate (10) has a basic body (14) provided with a central axle, and on which is fixed a soft, in relation to the basic body, intermediate layer having a polishing medium carrier (18). The intermediate layer has a radial inner zone (20) of mainly constant thickness and a radially outer zone connected thereto, whose radially outer dimensions starting from the basic body (14) to the carrier (18) increase, so that the elastic support of the polymer medium carrier by the intermediate layer (16) reduces in its radial outer zone to the outer edge (76) to the polymer media carrier. Independent claims are given for the following: (1) (A) A fine processing tool for optically effective surfaces. (2) (B) A method for fabricating a polishing plate.
