Abstract
The invention concerns a process and an apparatus for chip-cutting plastic material optical lenses. The point of chip-cutting on the lens is cooled. The chip-cutting is effected by means of lathing. The point of chip-cutting is locally cooled down to a temperature at which the plastic material becomes brittle such that the chip breaks into bits.
