摘要： PROBLEM TO BE SOLVED: To send the whole assist gas to a machining part at high flow speed and to conduct laser beam machining with effectively using the whole laser beam. SOLUTION: The assist gas Q supplied into an assist gas nozzle 16 is ejected from the opening part 16a of a nozzle tip toward the cutting part 2a of an object 2 to be cut. At this time, the opening diameter D of the opening part 16a is made roughly equal to a cutting width (w) and is smaller than a conventional opening diameter. Thus, an assist gas ejection speed is accelerated as well as the whole assist gas Q is sent into the cutting part 2a. Because the opening diameter is narrowed, the diameter of the inner circumferential face of the assist gas nozzle 16a is narrowed down, the narrowed down inner circumferential face is served as a reflection face 16a. The laser beam made incidence on the reflection face 16a is reflected and irradiated/converged toward the object 2. Thus, the whole laser beam 3 is contributed to machining.

摘要： PROBLEM TO BE SOLVED: To simplify the work at a high position by converging and irradiating the high-output infrared laser beam small in atmospheric attenuation from a long-focus converging mirror box mounted on a remotely-controllable mobile posture control means. SOLUTION: A first long-focus converging mirror 7 and a second long-focus converging mirror 8 are respectively arranged opposite to each other on a left upper part and on a right lower part inside a converging mirror box 6, and the mirror box reflects the infrared laser beam from an inlet, and irradiates it onto a work 5 at an upper and far point. The respective mirrors 7,8 have the large focal distance of >=5 m. The mirror box 6 is mounted on a position control means (an NC machine a robot, etc.), which is movable on a floor through the remote control, and moved downward of the work 5 to achieve the cutting work. Cutting at high position in a wide range is achieved by finely controlling the mirror box 6 in the horizontal or perpendicular direction to move the irradiation point of the laser beam.
