ABSTRACT:
An eyeglass lens grinding machine is provided in which a bevel can be easily formed on the periphery of an eyeglass lens in such a manner that those portions of the lens which will protrude from either the front or rear surface of an eyeglass frame are appropriately adjusted in areas where the edge thickness is great in order to achieve a good aesthetic appeal after the lens has been fitted in the frame. In the improved eyeglass lens grinding machine, the frame configurational data on the eyeglass frame and the layout data to be used in providing a layout of the lens corresponding to the eyeglass frame are entered. The edge position of a processed lens is detected on the basis of the entered data. A first bevel path is determined on the basis of the result of the detection. A second bevel path is obtained by tilting the first bevel path in such a way that it passes through a desired position on the lens edge and the bevelling of the lens is controlled on the basis of the second bevel path.
