<p>PROBLEM TO BE SOLVED: To provide a laser beam machining device having a simple construction, easy assembling/adjustment, a reduced production cost and an optical path adjusting means. SOLUTION: In the laser beam machining device in which a Y axis frame 5 is arranged above a material W to be machined, a Y axis carriage 33, which is arranged with a laser beam machining head, is movably arranged to the Y axis frame 5, the Y axis frame 5 and the material W to be machined are arranged relatively movable in a X axis direction, a laser beam oscillator 9, which is integrally mounted to the Y axis frame 5, is arranged to a X axis frame, an optical path length adjusting means 11, which keeps an optical length of a laser beam LB from the laser beam oscillator 9 to the laser beam machining head 7 constant, is arranged to the optical path between the laser beam oscillator 9 and the laser beam machining head 7.</p> |
