Laserstrahlschneidemaschine und Laserstrahlreflektor dafür.

摘要

A laser beam reflector for reflecting a laser beam from a laser oscillator in a direction away from said laser oscillator includes a mirror holder (3), a mirror retainer (6) removably coupled to the mirror holder (3), a bend mirror (7) coupled to the mirror retainer (6) for reflecting the laser beam and a detecting device (31) for detecting a positional relationship between the mirror holder (3) and the mirror retainer (6). A laser beam cutting machine utilizes the laser beam reflector. When the mirror holder (3) and mirror retainer (6) are coupled properly, laser oscillation is performed. When the mirror retainer (3) and holder (6) are coupled improperly, laser oscillation is terminated immediately by a control device of the laser beam cutting machine.
