Grinding optical lenses, involves only one changeable lens clamping device to hold lens fixed during processing with cup-shaped tools, enable gymbal movement for shaping tools

摘要

The method involves using cup-shaped and shaping tools. The lens (4) is fixed relative to the workpiece spindle during processing with annular cuts by cup-shaped tools and is movable during processing with shaping tools. Only one changeable lens clamping device is used, which hods a lens fixed during processing with cup-shaped tools and enables gymbal movement during processing with shaping tools. The lens is not unclamped between the grinding processes. It can be held by friction or vacuum. Independent claims are also included for the following: an arrangement for implementing the method.
