METHOD FOR ECCENTRICALLY ORIENTING A LASER CUTTING BEAM IN RELATION TO A JET AXIS AND FOR ANGLE CUTTING, CORRESPONDING LASER MACHINING HEAD AND LASER MACHINING TOOL

摘要

The present invention relates to a nozzle axis (3a) of the cutting gas nozzle (3), A method of directing the focused laser cutting beam to be 2 for the eccentric, turning mirror 12 arranged on the upstream side of the cutting laser beam in the beam path of the cutting gas nozzle (2) and (3) to the nozzle axis (3a ) and the beam of the laser cutting beam (2) coaxially disposed about the direction (C _SP ) as a center, and / or perpendicular to the nozzle axis and the direction changing mirror (3a) (12) It relates to an eccentric alignment of the laser cutting beam, which method comprises the corresponding direction to the direction of incidence (B ') to rotate around. Cutting the gas nozzle (3) and the turning mirror 12 is disposed in a second structural unit (9b) of the laser processing head 9, with respect to the second structural unit (9b) of the first structural unit (9a) corresponding to the direction (B) to the incident beam direction is arranged to rotate. The present invention also provides a method of oblique cutting work 1 using the laser beam on the basis of the method of orienting the laser cutting beam to be eccentric (2). And to a laser processing head 9, and a laser processing machine (7) for performing the method. ;
