MACHINING HEAD FOR LASER BEAM MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a laser beam machine having an ample spatial margin in the upper and lover directions against a focus position and capable of easily machining a material to be worked with an three-dimensional shape of different height. SOLUTION: In a machining head 1 for a laser beam machine which converges and emits laser beams 3 to a material to be worked 6, a condensing lens 11 to make laser beams incident on the bottom of the machining head is provided, and further a liquid injection nozzle 8 which injects high pressure liquid 5 passing through laser beams on the surface of the material to be worked as a liquid beam 7 below the condensing lens bordered by the condensing lens is provided.
