摘要
PROBLEM TO BE SOLVED: To provide a laser machining device capable of adjusting the converging diameter, the converging angle or the like of a laser beam without replacing an optical fiber connected to a machining head, and surely preventing contamination of an optical component in the machining head.SOLUTION: A laser machining device 1 according to the present invention includes a laser light source 2 for generating a laser beam, a first transmission part 31 and a second transmission part 32 for transmitting the laser beam generated by the laser light source 2, and a machining head 4 for converging the laser beam transmitted by the second transmission part 32 to radiate it to a workpiece W. The second transmission part 32 has a plurality of fiber cores FC, and transmits the laser beam to the machining head 4 by one of the fiber cores FC, and the exit end EE of each of the fiber cores FC facing the machining head 4 is arranged in a fixed manner to the machining head 4. The laser machining device 1 further includes a switching part 5 for switching, among the plurality of fiber cores FC, the fiber core FC for actually transmitting the laser beam to the machining head 4.SELECTED DRAWING: Figure 1
