Abstract

The current invention relates to a lens surfacing assembly and a method for grinding and polishing glass or plastic optical lenses. The assembly is primarily intended for use with a rigid lapping tool and a typical lens grinding machine. The lens surfacing assembly comprises a strippable adhesive member that is attached to the lapping tool for use throughout the grinding and polishing operation for attachment of a reversible, double sided lens surfacing pad having a coarse surface on one side and a fine surface on the other. After the grinding has been completed, the reversible pad is removed and a polishing cloth is attached to the adhesive member. The combined thickness of the pad and the adhesive member is equal to the compensation designed into the radius of curvature of the lapping tool arcuate surface. The combined thickness of the polishing cloth and the adhesive member is also equal to the compensation designed into the lapping tool.
