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, andwherein 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.

Abstract
A laser processing machine for processing workpieces, in particular metal sheets, includes a workpiece support and a beam receiver for the laser beam used as a processing tool. The distance between a workpiece lying on the workpiece support and the beam receiver is variable, owing to the fact that the workpiece support and the beam receiver are positionable relative to one another along the beam axis of the laser beam by means of an adjusting drive of an adjusting device with a positioning movement of a variably definable magnitude. A method for processing workpieces, in particular metal sheets, is also provided.
