ABSTRACT:
A subject lens is held by two chuck shafts, which are rotated synchronously by pulse motors during a grinding operation. Chamfering and other grinding wheels are mounted on a rotary shaft of a lens grinding part. A desired grinding wheel for each processing is selected by moving the rotary shaft vertically. In the case of rough processing, the rotary shaft is moved by a pulse motor toward the center of the chuck shafts based on lens frame shape data. In the case of chamfering, the rotary shaft is moved toward the center of the chuck shafts as well as vertically based on chamfering data. To produce part of the chamfering data, a lens measuring section measures the shapes of the front and rear surfaces of the subject lens.
