<p>The invention relates to a method and an apparatus for removing small-sized cut-out pieces, for instance in the form of discs, when cutting holes and other minor openings in a workpiece (2) by means of a cutting laser beam (1). A suction device (5) is arranged above the detail to be cut-out and located asymmetrically relative to the cutting laser beam. The suction nozzle (6) has a recess (11) for the nozzle tip (9) of the laser cutting nozzle (4) so that the laser cutting point (7) is located in the peripheral part of the suction nozzle (6). The cutting operation is carried out in such a way that it is completed when the cut-out disc is fully covered by the suction nozzle.</p> |
