Title (EN) LASER CUTTING METHOD, NOZZLE OF LASER MACHINING DEVICE, AND LASER MACHINING DEVICE
(FR) PROCÉDÉ DE DÉCOUPE AU LASER, BUSE D'UN DISPOSITIF D'USINAGE AU LASER ET DISPOSITIF D'USINAGE AU LASER
(JA) レーザ切断加工方法、レーザ加工装置のノズル、及び、レーザ加工装置
Abstract:
(EN) When this laser cutting method is applied to a metallic workpiece, the same assist gas is emitted from an inside nozzle and an outside nozzle of a nozzle having a dual structure in a laser machining head, and a throttle portion of the assist gas emitted in a conical shape from the outside nozzle conforms to the surface of the workpiece to perform laser cutting.
(FR) L'invention concerne un procédé de découpe au laser. Lorsque ledit procédé est appliqué à une pièce à travailler métallique, le même gaz d'assistance est émis à partir d'une buse intérieure et d'une buse extérieure d'une buse ayant une structure double dans une tête d'usinage laser, et une partie d'étranglement du gaz d'assistance émis en une forme conique à partir de la buse extérieure se conforme à la surface de la pièce à travailler pour effectuer une découpe au laser.
(JA) 金属製ワークをレーザ切断加工方法する際に、レーザ加工ヘッドの二重構造を有するノズルの内側ノズルと外側ノズルとから同一のアシストガスを噴出し、外側ノズルから円錐状に噴出されたアシストガスの絞り部分をワークの表面に合せてレーザ切断加工する。
