<p><P>PROBLEM TO BE SOLVED: To provide a laser beam machining head and a laser beam machining apparatus in which degradation of wires caused by twist and entanglement of wires and pipes of an optical fiber, a camera, a cooling device or the like is prevented in advance, the control is simplified, and the machining speed is increased. <P>SOLUTION: In a laser beam machining head 300 capable of irradiating laser beams on a work surface in a substantially circular shape, the laser beam machining head 300 comprises an output side machining head part 100 having a nozzle to irradiate the laser beams on the work surface and rotatable around a normal on the work surface as a center of rotation, and an input side machining head part 200 which has an optical fiber to introduce the laser beams, and is relatively rotatable with respect to the output side machining head part 100 and limited in the self-rotation. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
