<p>The subject-matter of the invention is a machine tool for the abrasive machining of workpieces by means of a laser beam, with a housing (15) which is mounted on a machine column (2) and in which a guide tube is arranged so as to be longitudinally displaceable. Mounted at the rear end section of the housing is a laser unit (18), the laser beam of which passes through focusing optics and comes out of a nozzle head, in which means of feeding at least one fluid to the central discharge opening of the laser beam are provided. So that stock removal by machining can also be carried out on a workpiece (12), a hollow motor-driven work spindle (25) with locking elements (27) for clamping a tool holder (28) is mounted according to the invention in the housing (15). The focusing optics and the nozzle head (20) are conveniently attached to a standardised tool holder (29) which can be interchangeably fitted into the work spindle. <IMAGE></p> |
