<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machine which is formed in a box surrounding a laser beam machining head moving at high speed and its moving mechanism, and can reliably seal an opening part from which the tip of the laser beam machining head is protruded with sufficient durability. <P>SOLUTION: A laser beam machining head 2 is provided in a high-speed cut box 3 movably provided in X-axis and Y-axis directions so as to be independently movable from the high-speed cut box 3 along the U-axis direction and the V-axis direction which are parallel to X-axis and Y-axis respectively while its tip is protruded from the box. An opening part 10 for protruding the tip of the laser beam machining head 2 therefrom is formed in the exterior wall 3a of the box 3. A flange part 20 for covering the opening part 10 with a predetermined space S from the exterior wall 3a is provided to the laser beam machining head 2. An air feed means 21 for feeding air and discharging the air outside is provided in the space S. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
