An eyeglass lens processing apparatus for processing an eyeglass lens includes: a lens chuck that holds the lens; a roughing tool; a finishing tool; a finishing data input unit that inputs finishing data; a water supply unit that supplies water to a portion being processed of the lens; a first temperature sensor that senses temperature of the water to be supplied; and an operating unit that corrects the input finishing data based on the temperature sensed by the first temperature sensor.

An eyeglass lens processing apparatus includes a processing control unit (50) which in the soft processing mode, roughs the lens such that the torque threshold value is set to a value Tθs lower than the threshold value TθN of a normal processing mode, and when torque detected by a sensor unit does not exceed the threshold value Tθs, a axis-to-axis distance varying unit or a lens rotating unit is controlled so that a cutting amount per rotation of the lens reaches a threshold cutting amount, and when the detected torque exceeds the threshold value Tθs, the axis-to-axis distance varying unit or the lens rotating unit is controlled so that the torque becomes lower than the threshold value Tθs to decrease the threshold cutting amount.

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.
