PURPOSE:To offer the laser hole method which can improve surely the efficiency for hole working, and also, does not cause deterioration of the hole quality. CONSTITUTION:In the laser hole machining method for executing successively performation working plural objects to be worked 15A-15D installed on plural working optical axes 17A-17D by radiating a laser beam oscillated pulsatively by switching successively to plural, working optical axes 17A-17D by synchronizing with the time of non-excitation of this laser beam, whenever perforation of one hole to one object to be worked (one of 15A-15D) is completed, the laser beam is switched successively to other working optical axis. |
