Abstract
A laser machining head for machining a workpiece by a laser beam. The head has a head housing through which the laser beam passes along a central axis. A carrier member for a lens optics system for focusing the laser beam is mounted on the head housing and is displaceable relative to the latter in the direction of the central axis. A first setting device includes a cable connected to the carrier member and a cable drum connected to the head housing for winding up the cable in order to move the carrier member towards the head housing. A second setting device causes the carrier member to be displaced in the direction away from the head housing, with the second setting device being separate from the first setting device.
