Paper Abstract

The manufacturing of glass lenses has always set exacting requirements on the finishing technique. If, in addition, the design deviates from the conventional geometry of plane and sphere, the standard manufacturing process of rough grinding with cup-wheels and subsequent precision grinding and polishing with reproductive techniques fails. In order to achieve highest form accuracies and surface qualities combined with a flexible surface shape, ductile single- point-grinding meets the requirements for the production of rotationally symmetric aspheres.
