Laser processing machines, such as laser cutting machine, including a work table receiving workpiece, and work arm with a laser cutting head. Laser cutting head includes nozzle receiving device and nozzle. Via nozzle laser beam may be directed onto work piece. Machine includes main drives moving work arm and/or the laser cutting head on X-Y-Z axes to process work piece, as well as an alignment unit to adjust laser beam. An adjusting station includes receiving unit fixing nozzle and/or the nozzle receiving device during centering of nozzle. The alignment unit has head element in laser cutting head. Head element receives nozzle and/or the nozzle receiving device and is slidable in X-Y directions, via the main drives. Head element may be fixed in a selected position, within the laser cutting head, via clamping device releasable during nozzle centering at adjusting station.

Laser processing machine

Laser processing machines, such as laser cutting machine (LM), including a work table receiving workpiece (W), and work arm () with a laser cutting head ().
