PURPOSE:To prevent the failure of the work and to improve laser machining accuracy by providing a dross removing means in tight contact with the surface of the work on the side opposite from the side to be irradiated with a laser beam and machining the work and the means simultaneously. CONSTITUTION:The work 6 and a dross removing means 14 are worked simultaneously with a laser beam 1'. The melt of the work 6 and the means 14 is pushed by a jet 8 and dross 15 sticks at the curving end of the means 14. If the means 14 is removed from the work 6 after the machining with the beam 1' is completed, the dross 15 is removed without sticking at the curved end of the work 6 and the damaging of the work 6 is obviated. |
