Eyeglass lens processing apparatus

摘要

An eyeglass lens processing apparatus comprising: an edge position measuring unit for measuring an edge position of the lens; a moving unit that moves a feeler with respect to the lens chuck shaft; and a speed controller that calculates radius vector moving data for the moving unit with respect a rotating angle of the lens chuck shaft based on target lens shape data, and calculates a rotating speed of the lens chuck shaft rotating unit based on a change of the moving data with respect to a change of the rotating angle of the lens chuck shaft. The rotating speed at an area where the change of the moving data with respect to the change of the rotating angle is small is higher than the rotating speed at an area where the change of the moving data with respect to the change of the rotating angle is large.
