Suction device, laser processing machine and method for suction

摘要

The invention relates to a suction device (120) set up for a laser processing machine (100) with a laser processing head (106) which can be moved over a workpiece holder (112), with a blower (122) and a plurality of which can be selectively opened and are in communication with the blower (122) Flaps (126) for generating an air flow, and set up with a controller (300) for detecting the position and the operating state of the laser processing head (106) and for controlling (300) the flaps (126) depending on the detected position and the operating state of the Laser machining head (106).
