Patent ID: 7480970

Claim:
A machine for machining optical workpieces having a face to be machined, said machine comprising: a workpiece spindle that can rotatably drive said workpiece about a workpiece rotation axis which passes through the face of said workpiece; a first fast-tool assembly, that moves a turning cutter towards the face of said workpiece and away from the face of said workpiece; said first fast-tool assembly comprising a first actuator and a first shuttle which is assigned to said first actuator and carries said turning cutter; the workpiece spindle and the first fast-tool assembly being movable relative to each other in a direction transverse to the workpiece rotation axis; a second fast-tool assembly positioned adjacent to the first fast-tool assembly and having a graver; said second fast-tool assembly comprising a second actuator and a second shuttle which is assigned to said second actuator and carries said graver; and said graver terminating with a point that tapers towards an end which faces the face of said workpiece and is essentially punctiform, said graver having no cutting edge that is contiguous with the punctiform end, and wherein the graver is movable by the second fast-tool assembly towards the face of said workpiece and away from the face of said workpiece, so that, through needling engagement of the graver with the face of said workpiece, a marking can be produced on the face of said workpiece.
