<p><P>PROBLEM TO BE SOLVED: To solve a problem of a dust collection force fluctuating depending on the number of laser beam machines in operation, in the dust collection of a plurality of laser beam machines by one dust collector, wherein dust collection shutters of the laser beam machines connected therewith open and close at random by the start and stop of the respective laser beam machines. <P>SOLUTION: A switching device having a bypass hole is installed between the respective laser beam machines and the dust collection equipment that collects by suction the gas and slag generated during the machining of workpieces. Thus, the sucking direction is switched to the respective laser beam machines and the bypass hole. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
