<p>Provided is a laser machining apparatus capable of preventing debris generated in laser machining from being attached to an intake passage of a dust collecting unit. The laser marching device includes a machining head (36) for irradiating a workpiece with a laser beam, and the machining head includes a dust collecting unit (70) interposed between a light condensing lens (41) and the workpiece to collect debrises generated as the laser beam condensed onto the light condensing lens is irradiated onto the workpiece. The dust collecting unit has one end connected to a suction member and an opposite end having a suction path (78) formed in an open top surface of the workpiece, and the laser machining device further includes a cleaning solution supply unit (82) for supplying a cleaning solution to the suction path. [Reference numerals] (80) Suction member; (88) Cleaning solution supplying source</p> |
