Abstract:
1. A laser processing machine for processing workpieces, the machine comprising: a workpiece support configured to support a workpiece; a laser processing head configured to deliver a laser beam; a beam receiver with a receiving opening for the laser beam, which the laser beam enters after piercing through the workpiece, the laser processing head being arranged on one side of the workpiece and the workpiece support and the beam receiver being arranged on an opposite side of the workpiece; and an adjusting device configured to vary the distance between the workpiece and the beam receiver existing along a beam axis of the laser beam, wherein the adjusting device comprises an adjusting drive configured to position the workpiece support and the beam receiver relative to one another with a positioning movement of variably definable magnitude along the beam axis, and wherein the adjusting drive comprises a drive control configured to variably define the magnitude of the positioning movement with which the workpiece support and the beam receiver are positioned relative to one another along the beam axis.
