PURPOSE:To elevate the utilization rate of a laser beam machine by supplying selectively and yet at the specified time intervals to a work disposed on plural working tables a laser beam supplied from an unit of a laser beam supplying source and by performing the machining in order. CONSTITUTION:A laser beam distributing device consisting of the 1st mirror 11 and the 2nd mirroe 13 which rotate by a pulse motor 1 is provided between a laser beam supplying source 1 and plural working tables 2, and a working machine 20A... corresponding to each laser beam L1... is arranged. When either of works 3 is in a condition to receive the irradiation of a laser beam L, the laser beam distributing device is driven by a distribution controller 10 according to a demand signal Vd transmitted from a demand signal generator 6 and the work 3 is worked in order by the working machine 20. While the laser machining is executed, however, the delivery-in and delivery-out works of the work 3 are performed. The utilization rate of a laser beam machine and utilization efficiency of energies are thus elevated. |
