摘要

Apparatus machines material by laser beams eg for cutting welding or engraving. It includes a numerical control system for coordinates of a high- precision guide system 38 and a laser beam source (1) having a telescopic system (2) outside the material (13) to be machined so that the highly reflective part of the laser radiation is guided from the source (1) via deflecting mirrors to a laser cutting head under units (12, 21 ). A first measuring means (11), a first setting element (17), an automatically adjustable adjusting mirror (22) and a second setting element (18) are disposed in the zone of the source (1) and are connected to a second measuring means (12), which contains a measuring orifice (21) locked on the high- precision guide system (38) by a voltage U1 (9). Also provided are a measured value voltage device (3), a first amplifier (4), a first controller (6) of a limit value adjustment, and a second amplifier (5) connected to controller (6) by an external guide voltage.
