    摘要： An eyeglass lens grinding machine, which is designed to effectively utilize the grinding capability of abrasive wheels so as to perform efficient grinding operations. The eyeglass lens grinding machine includes a lens rotating section which holds and rotates a lens to be processed, an abrasive wheel rotating section which rotates an abrasive wheel for grinding the lens on its own axis, an abrasive wheel's rotational state detecting section which detects the state of rotation of the abrasive wheel caused by the abrasive wheel rotating section, and a rotation control section which variably changes the rotation of the lens rotating section on the basis of the result of the detection. The rotation control section issues a command to either stop or slow down the rotation of the lens if the load on the rotation of the abrasive wheel exceeds a predetermined reference level and issues a command to have the lens rotation return to the initial state if the load becomes lower than the reference level.

    摘要： In a lens grinding apparatus, shape data of an eyeglass frame and layout data of an eyeglass lens for the eyeglass frame are input. Edge positions of front and rear surfaces of the eyeglass lens are measured on the basis of the input data. The position variation information of the front and rear surfaces of the lens with respect to a radius vector is input. An inclination angle of a finishing grinding wheel is stored. Edge positions after a finishing process are calculated on the basis of the measured edge positions, the input position variation information, and the inclination angle of the finishing grinding wheel. A chamfering grinding wheel for chamfering edge portions of a finish-processed eyeglass lens is controlled on the basis of the edge positions obtained by the edge position calculation. A chamfering process is easily performed, and particularly chamfering is uniformly performed.
