Abstract:
1. A method for processing surfaces of optical workpieces having non-rotationally symmetrical and/or aspherical surfaces, such as lenses or spectacle glasses, by means of at least one tool which is fed by means of a tool feed unit for the processing of the non-rotationally symmetrical and/or aspherical surfaces, at least one optical workpiece being held in a workpiece fixture rotating about an axis of rotation of a workpiece spindle, the at least one optical workpiece being received by the workpiece fixture in such a way that the axis of rotation of the workpiece spindle runs at a distance from a workpiece axis of the at least one optical workpiece, and from a longitudinal axis of the workpiece fixture, the longitudinal axis of the workpiece fixture lying at least approximately parallel to the axis of rotation of the workpiece spindle, and the axis of rotation being coupled to the feed movement of the at least one tool.
