Abstract
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.
Claims10
An eyeglass lens processing apparatus for processing an eyeglass lens, the apparatus comprising:
- 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 for processing an eyeglass lens, the apparatus comprising;
- a lens chuck that holds the lens;
- a roughing tool;
- a finishing tool;
- a target lens shape data input unit that inputs target lens shape data;
- a water supply unit that supplies water to a portion being processed of the lens;
