Laser processing machine
First Claim
1. A process for aligning a laser processing machine laser beam, the method comprising:
- moving a laser head to a nozzle adjustment station with laser head main drives;
placing a nozzle of the laser head in a nozzle receiving unit of the nozzle adjustment station;
fixing, in the receiving unit, the nozzle of the laser head against movement under action of the laser head main drives;
controllably releasing a clamping device in the laser head to allow lateral sliding between the nozzle fixed in the nozzle receiving unit and the laser head;
aligning a laser beam in the nozzle by repositioning the laser head with the laser head main drives; and
activating the clamping device to fix the beam-aligned nozzle to the laser head.

Abstract
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.

16. A process for aligning a laser processing machine laser beam, of the method comprising:
-
moving a laser head to a nozzle adjustment station with laser head main drives; placing a nozzle of the laser head in a nozzle receiving unit of the nozzle adjustment station; fixing, in the receiving unit, the nozzle of the laser head against movement under action of the laser head main drives; determining a position of the laser beam; releasing a clamping device in the laser head to allow lateral sliding between the nozzle fixed in the nozzle receiving unit and the laser head; repositioning the laser head with the laser head main drives based on the determined position of the laser beam such that the laser beam is aligned with respect to the nozzle; and activating the clamping device to fix the beam-aligned nozzle to the laser head. - View Dependent Claims (17, 18, 19, 20)
