A method for orientating a focused laser cutting beam eccentrically relative to the nozzle axis of a cutting gas nozzle and a laser processing machine for performing the same, the method including: arranging a redirecting mirror in a beam path of the laser cutting beam upstream of the cutting gas nozzle, the mirror being rotated about a direction which is coaxial with the nozzle axis and/or about a direction which is perpendicular relative to the nozzle axis and which corresponds to the beam incidence direction of the laser beam on the redirecting mirror. The cutting gas nozzle and the redirecting mirror are arranged in a second structural unit of a laser processing head, for rotation about the direction corresponding to the beam incidence direction relative to a first structural unit.

Orientating a laser cutting beam

A mechanical arrangement () for processing rod-like workpieces, especially pipes (), has a processing device () for processing a workpiece, a workpiece-moving device () for moving workpieces () relative to the processing device (), and a device () for supporting a workpiece in the direction of gravity. The device () for supporting a workpiece includes at least one support roller () which forms at its outer periphery a workpiece rest. The workpiece rest at the outer periphery of the support roller () extends about a roller rotation axis () of the support roller () at a changing center distance. The support roller () is rotatable about the roller rotation axis () in a controlled manner and is thereby positionable in different rotational positions.

A bending press has a drive mechanism for effecting vertical movement of a bending tool in a bending line, a drive actuating device, and a locking mechanism for the actuating device. A stop assembly behind the bending line includes a rail, a rail drive mechanism to move the rail perpendicularly to the bending line, and at least two stops on said rail. A releasable clamping mechanism fixes the stops in position on the rail, and the stops are movable along the rail upon release of the clamping mechanism. A clamp locking mechanism locks the clamping mechanism in a clamp fixing position. The stop assembly is movable into a position in which the stops project over the bending line when the drive locking mechanism is actuated, and the clamp locking mechanism is actuatable to release the clamp locking mechanism when the drive locking mechanism is actuated.
