Abstract
Laser machining is often carried out using special machines or apparatus, with the workpieces having to be finished afterwards using appropriately equipped cutting machine tools. According to the invention, a laser beam (5) is supplied on the head-stock (17) of a machine tool (13), by means of a beam control tube (12). Said beam radiates into a focussing lens (35) at an articulation point (D). Said articulation point (D) is precisely guided and held in place in a centring cone (36) with its focussing lens (35) located underneath. The laser-machining head can be removed from the headstock (17) by means of a swivel mechanism and the machine (13) can carry out cutting operations in the usual way. The laser-machining operations are carried out before the cutting work in the processing cycle, a zero-offset being provided between the laser machining and the cutting work, correcting any system errors with the help of a computer.
