An apparatus for the laser processing of workpieces with shortened processing time. Two laser units that can be simultaneously operated are directed towards each other. Workpieces, for example printed circuit boards, are moved between the two laser units such that the two sides of the workpieces are simultaneously processed. As a result the processing time is considerably shortened.

Device for the laser processing of workpieces

A method and arrangement for calibrating a laser processing machine for processing workpieces. The present invention ensures a fast and reproducible method and arrangement for calibrating a laser processing machine by measuring a position of a predetermined test pattern on a test plate while taking into account any imaging errors caused by the deflection unit.

Method and device for calibrating a workpiece laser-processing machine

A workpiece, designed as a printed circuit board for example, can be moved by means of a transport device under a laser unit in such a way that a region to be machined of the workpiece passes into the deflecting region of the laser beam. The workpiece is set between clamping jaws to a vertical position in which the laser beam is focused exactly on that surface of the workpiece which is to be machined. As a result, the machining accuracy can be considerably increased.
