LENS RETAINING DEVICE FOR RETAINING A RAW LENS IN A PROCESSING MACHINE, AND METHOD FOR PROCESSING RAW LENSES

摘要

A processing machine that has a lens retaining device for retaining a raw lens in a processing machine has a tool mount for immobilizing the lens retaining device in a processing tool, and a workpiece mount for receiving a raw lens to be processed. The workpiece mount has a curved surface and is connected to the tool mount. An air channel extends from the tool mount to the curved surface of the workpiece mount. Furthermore, the workpiece mount has an adhesion element which at least to some extent forms the curved surface, wherein the adhesion element has adhesive properties on the curved surface. When processing raw lenses with such a retaining device, the raw lens is retained on the retaining device by means of the adhesion element and by generating a vacuum so that the raw lens is retained solely by means of the adhesion element during processing.
