Patent ID: 7597033

Claim:
A machine for machining optical workpieces having a prescription surface to be machined, the machine comprising: a workpiece spindle, by means of which the workpiece can be driven in rotation about a workpiece rotation axis (B) that runs through the surface of the workpiece, a fast tool arrangement, by means of which a turning tool can be moved in a fast tool movement direction (F 1 , F 2 ) towards and away from the surface of the workpiece to engage the turning tool with the surface, wherein the workpiece spindle and the fast tool arrangement can moreover be moved relative to one another in a further direction (X) transverse with respect to said fast tool movement direction (F 1 , F 2 ); said further direction (X) and said fast tool movement direction (F 1 , F 2 ) forming a fast tool movement plane, and said further direction (X) and said workpiece rotation axis (B) forming a second plane; and wherein said fast tool movement plane is positioned obliquely at an angle α with respect to said second plane.
