PURPOSE:To widen the range for work cutting and to surely remove the dross generated at the time of cutting by disposing a dust collecting nozzle operating in synchronization with a laser cutting nozzle so as to face the laser cutting nozzle. CONSTITUTION:The work (a) transported onto a stage 3 is cut by the laser cutting nozzle 1. The dross generated at the time of the cutting is successively sucked away by a dust collecting nozzle 2 moving in synchronization with the laser cutting nozzle 1, by which the adhesion of the dross to the work is prevented. The dust collecting nozzle 2 moves in synchronization with the laser cutting nozzle 1 and therefore the dross is surely sucked away even if the position of the cutting changes. |
