PURPOSE:To prevent a laser light being projected outside and to obtain a safe laser machine by providing a heat resistant absorbing body on the inner wall face of a pair of column parts and composing the rotary body having a nozzle so as to turn within the range of a pair of the columnar parts. CONSTITUTION:When a work fitting base 2, moving body 4, lifting body 5, rotary body 7a and turn table 9 are relatively driven, in case of working, the rotary body 7a is turned in the Y axial direction orthogonal with the X axis in the moving direction of the work fitting base 2. The rotary body 7a equipped with a nozzle 8 is provided so as to turn within the range in the X axial direction of the columnar part couple forming a gate column 3. Accordingly, the laser light coming off the work fitting base 2 is not projected to the outside of the laser machine by being intercepted by the columnar part inner wall 10 of the gate column 3 even if the rotary body 7a is approached to the horizontal position with its turning. And yet due to a member 11 being provided on the columnar part inner wall 10 the laser light is absorbed or reflected with diffusion. |
