ABSTRACT:
A laser machining apparatus having a laser oscillator connected to a laser robot by a beam transmitting apparatus made of beam ducts, in which the beam ducts are hermetically sealed between the outlet of the laser oscillator and the laser beam outlet of laser robot, and a working gas supplying inlet is mounted at an upper portion of the beam ducts for transmitting of the gas through the beam ducts and outputting of the gas at a nozzle in the laser robot head. According to the above construction, the present invention is able to prevent an occurrence of the heat lens phenomenon, and also able to prevent fumes and dust from entering into the beam duct.
