<p>The invention relates to a device and a method for cutting workpieces (1.4) using a laser beam. The object of the invention is to reduce the necessary cutting time, while at the same time minimizing the cutting gas consumption and the influence of forces or moments acting due to acceleration. In a device according to the invention, a laser beam is deflected two-dimensionally using at least one reflecting pivoting element (1.1) and is directed together with a cutting gas at the surface of the workpiece through a cutting tip (1.3) using a focusing lens (1.2). To this end, a biaxial relative movement is carried out between the workpiece and laser beam using elements received in a cutting head (1). In order to cut a larger region, the cutting tip (1.3) fastened to the cutting head (1) is additionally moved by at least one drive (7, 7.1, 7.2) in two axial directions parallel to the surface of the workpiece, concentrically to the beam deflection. Due to the overlap of the axial movements, the overall system becomes considerably more dynamic.</p> |
