PURPOSE:To effectively perform the machining of the face to be machined and to improved the machining efficiency as well by performing a machining with spraying on the face to be worked an absorber increasing the absorption factor of a laser light from the coating device integrally fitted with a laser torch. CONSTITUTION:An absorber L is mistily fed out from the spraying head 26 formed by the pipe stock which is fitted to a mobile member 11 via bracket 27, bending the tip thereof to the face Wa to be machined and fitting the guard 28 for preventing the scattering as well. A graphite, boron nitride, etc., are used as the absorber. With the machining of this composition the machining efficiency can be improved. |
