Laser processing apparatus having plural processing nozzles

摘要

The present invention relates to a laser processing apparatus. This laser processing apparatus has plural processing nozzles such as a cutting nozzle and a welding nozzle which are held by a processing nozzle holder. The processing nozzle holder can be rotated with respect to a processing head with a condenser lens disposed therein. Therefore, substitution can be performed easily to a processing nozzle best suited for a desired thermal processing out of various thermal processings, and efficient processings can be executed.
