MACHINING HEAD FOR A LASER MACHINING TOOL, LASER MACHINING TOOL, AND METHOD FOR REPLACING A PROTECTIVE GLASS IN THE MACHINING HEAD

摘要

The invention relates to a machining head for a laser machining tool (10) for machining a workpiece (6) by means of a laser beam (5), which is focused by means of a focusing optical unit (17) arranged in a first housing part (12) and exits the machining head (3) through protective glass (29) arranged after the focusing optical unit (17) in a beam propagation direction, wherein the protective glass (29) is arranged in a second housing part (14), which is detachably fastened to the first housing part (12) and which remains connected to the first housing part (12) by means of a coupling element (31) after the detachment from the first housing part (12) and which can be at least translated or pivoted with respect to the first housing part (12).
