<p>PROBLEM TO BE SOLVED: To lighten the frame of a laser cutting 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, whereby a ladder shaped frame 2 is constituted. The driven wheel unit 3 having the wheel 3b coming into contact with the upper surface of the rail 1a and the side face wheel 3c coming into contact with the side face of the rail 1a is installed to the position corresponding to the rail 1a of respective gutters 2a, 2b. The driving motor 4 fixed a pinion 4a is installed to the position corresponding to the rack 1b fixed to the rail 1a between respective gutters 2a, 2b. A laser oscillator 5 is installed to the upper surface of the frame 4, and an emitting port 5b is connected to the laser torch 9 mounted on the carriage 10 traversable long the gutter 2a, whereby the laser optical path 6 having an inverting mirror 7 is formed.</p> |
