摘要

There is disclosed a lens grinding apparatus having a lens rotating shaft (15) on which a lens to be ground is mounted and a grinding wheel (21) for grinding the lens. The invention is characterized in that the lens grinding apparatus comprises outer diameter measuring means (17) for measuring the outer diameter of the grinding wheel, arithmetic means for calculating a wearout quantity of the grinding wheel based on a measurement made by the measuring means, adjusting means (24) for adjusting an intershaft distance between the lens rotating shaft and a grinding wheel rotating shaft, and control means for controlling the adjusting means based on the wearout quantity and performing a wearout correction.
