摘要

Machining robot has a machining laser (1), and a lens arrangement (4) for focusing a machining laser beam (5) between the penultimate (19) and last (2) head axes. The last head axis (2) includes a laser nozzle (7) for the laser outlet. The effective focal length (9) of the lens selected so that the radiation cross-section (11) at the last turning surface (12) of the turning device (6) in front of the laser nozzle (7) is more than 20% of the incident radiation cross-section (10).
