ABSTRACT:
A apparatus comprises a portion for setting a load133which sets the load of pressing a lens to a rotating tool, a portion for setting the rotation speed of a lens shaft132which sets the rotation speed and the direction of rotation of a lens-holding shaft and a portion for setting the condition of water supply134which sets the condition for injecting a cooling liquid to the lens. These conditions are set in each step of the processing of the lens. The load, the relative directions of rotation of the lens and the rotating tool (the up cut or the down cut) and the condition for injecting the cooling liquid are controlled based on the conditions of the processing set by the above portions.
