Abstract (en)
[origin: EP0995548A1] The grinding method for optical lenses involves turning a lens blank (1) around a rotary axis (Y-Y) parallel to the axis (X-X) of a train of grinding wheels (5). The spacing between the axes is controlled as a function of the angular position of the blank. The temperature is sensed as a function of distance from the working area to adjust the spacing.
