Abstract
An eyeglass lens processing apparatus for processing a periphery of an eyeglass lens, includes: a lens rotating shaft which holds and rotates an eyeglass lens to be processed; an abrasive wheel rotating shaft movable between a retracted position and a processing position; a chamfering abrasive wheel which is attached to the abrasive wheel rotating shaft and which chamfers the lens while receiving a processing load from the lens during processing; a detecting unit which detects the load to the chamfering abrasive wheel; and a control unit which issues a control signal for relatively moving the lens and the chamfering abrasive wheel one from another to reduce the processing load if the detected processing load is higher than a predetermined first level and for continuing the chamfering, and which issues a control signal for ending the chamfering if the detected processing load over the entire periphery of the lens is lower than a predetermined second level.
