<p>PROBLEM TO BE SOLVED: To rationally execute cooling of the laser oscillator in a laser cutting device and suction of dust, moreover to lighten the whole device and to realize the smooth operation. SOLUTION: Two gutters 2a, 2b are arranged in the direction orthogonal to a rail 1a and connected with plural connecting members 2c to constitute a frame 2, and the driven wheel unit 3 having a wheel 3b and a side face wheel 3c is installed to the position corresponding to the rail 1a of gutters 2a, 2b. A laser oscillator 5 is installed to the upper surface of the frame 2, and a dust collector 13 and a cooling unit 14 are arranged to the position corresponding to one side of rail in the side of an emitting port 5b. The laser optical path 6 having an inverting mirror 7 is formed connecting the laser torch 9 mounted on the carriage 10 traversable along the gutter 2a.</p> |
