LASER BEAM SURFACE MACHINING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a laser beam surface machining device in which drilling or surface treatment is done with high machining efficiency and machining quality.

SOLUTION: The laser beam surface machining device comprises: a plurality of fiber laser oscillators 10; and an output controller 16 applying on.off control to laser beam output, and applies the drilling or the surface treatment to an object to be machined 1 relatively moving with respect to the output terminals of optical fibers. The output terminals of the optical fibers 12 are one- dimensionally or two-dimensionally and linearly arranged. The laser beam is successively irradiated from the plurality of optical fibers 12 aligned in the moving direction. The output controller 16 controls irradiation cycle so that the laser beam may be irradiated several times at the same machining section.
