  • the device according to the invention makes possible a treatment method in which an angle at which a treatment medium impinges on the workpiece and / or a speed, with which the treatment beam is guided over the workpiece, permanently varied, whereby a particularly treatment-active effect is achieved. It is thus achieved a permanent vectorial change in the direction in which a treatment beam passes over the workpiece, and / or the angle at which the treatment beam impinges on the workpiece, whereby workpieces with complicated surface geometries can be effectively cleaned.
