Laser machine tool with beam guide

Abstract

A machine tool for the machining of workpieces by means of a laser beam (13) includes a laser beam generator (12) that is located in an elevated position relative to a beam bender system (19) of a beam trombone (20). The beam bender system (19) of the trombone (20) can be moved under the laser beam generator (12). A beam guide (14) includes a beam-guiding element (15) that is positioned in the path of the laser beam (13) between the laser beam generator (12) and the beam bender system (19) of the trombone (20) and serves to redirect the laser beam (13) emitted by the laser beam generator (12) to the beam bender system (19) of the trombone (20). The beam bender system (19) of the trombone (20) and the laser cutting head (7) can be moved in the direction of a common axis of travel (x-axis) by means of drive units (8, 9, 21) with drive wheels. At least one drive wheel associated with the beam bender system (19) of the trombone (20) and at least one drive wheel associated with the laser cutting head (7) cooperate with at least one common drive shaft that extends in the direction of the common axis of travel (x-axis) of the beam bender system (19) of the trombone (20) and of the laser cutting head (7).
