<p>PROBLEM TO BE SOLVED: To effectively utilize energy by decreasing air consumption and to prevent dust intrusion from rear side of a work being in laser beam machining on a lower turret by applying a simple structure and operation in a laser beam- punch composite machine. SOLUTION: A machining head 2 constituting a laser beam machining part is communicated with an upper dust collector 5 through a machining head cover 1, and at the same time is also communicated with a lower dust collector 8 through a cartridge 3; discharged air (a) from the upper dust collector 5 and discharged air a' from the lower dust collector 8 are assembled, the assembled discharged air A is reused to form an air layer AS, and the air layer AS is made to flow out into the laser beam machining side part toward a die D on a lower turret 12 constituting a punching part.</p> |
