    摘要: The invention relates to a beam-forming unit (1) for focussing a laser beam (3) on a workpiece (9) for laser machining, comprising: a first optical element (5) which the laser beam (3) strikes, a second optical element (7) which is arranged downstream of the first optical element (5) in the beam propagation direction, and focussing optics (8) arranged downstream of the second optical element (7) in the beam propagation direction, wherein a first focus setting device (10) for setting a focus diameter (D) by influencing the first optical element (5) is assigned to the first optical element (5), wherein a second focus setting device (12) for setting a focus length in the beam propagation direction of the laser beam (3) by influencing the second optical element (7) is assigned to the second optical element (7), and wherein the laser beam (3) is reproduced on the second optical element (7) by the first optical element (5) via an intermediate focus (6). The invention also relates to a method for activating the beam-forming unit (1).

    摘要: In the case of a laser processing machine (1) for processing workpieces (2) by means of a laser beam (3), comprising a work support (4) for workpieces (2) to be processed, a traversing unit (5), which can be made to traverse along one or a least two main axes (X, Y) in relation to the work support (4), and an optical processing unit (6), which is provided on the traversing unit (5) and focuses the laser beam (3) on the workpiece (2) to be processed, it is provided that the processing unit (6) is mounted pivotably at its one end (6a) with respect to the work support (4) on the traversing unit (5) about one or at least two additional axes (A, B), that a drive (7) is respectively provided for each additional axis (A, B) on the traversing unit (5) or on the processing unit (6) for deflecting the other end (6b) of the processing unit (6) with respect to the work support (4) about the respective additional axis (A, B), and that a controller (8) is provided, which divides a desired path of the laser beam (4) on the workpiece (2) into a movement of the traversing unit (5) along the one or at least two main axes (X, Y) and a deflection of the processing unit (6) about the one or at least two additional axes (A, B) and activates the drives (7, 8) of the traversing unit (5) and of the processing unit (6) correspondingly.
