PURPOSE: To prevent the rear of a work from being damaged owing to the reflected wave of a laser beam, and to provide a laser beam cutting device holding the work in a vertical position to drop and remove a cutter. CONSTITUTION: An object to be worked is suspended by one or more grab, and is guided while it has no supporting member on its rear in a vertical or almost vertical position by guides 18 and 19. A cutting head 11 is guided by head guide apparatuses 5 and 6, and cutting is performed. A cut member is dropped on a transporting belt 17 removing the cut member, and can be brought out. On the grab, a sucking device for smoke generated at the time of cutting, is arranged. |
