Abstract
System for grinding eyeglass lenses with at least one grinding disk, a rotatable holder for an eyeglass lens blank, a device to control the grinding process in accordance with pre-determined optical values and/or a predeterminable outline of a glass lens, a CNC controlled manipulator to insert an eyeglass lens blank in the holder in an exact position, and an input device for the decentration values for the predetermined outline in reference to the optical center of the eyeglass lens. The utilization of the manipulator eliminates the difficult and time-consuming centering of the eyeglass lens blank by hand so that a plurality of eyeglass lens grinding machines can be loaded by a single manipulator.
