Abstract:
A laser machining device capable of recovering an exhaust performance of a dry pump easily is provided. A laser machining device includes: an oscillating portion that generates a machining laser beam G; an enclosure portion in which a first gas is enclosed; and an exhausting portion that exhausts the first gas together with a dirt generated in the enclosure portion in association with an operation of the oscillating portion. The exhausting portion includes: a dry pump; a first line that connects the enclosure portion and the dry pump; a second line that supplies a second gas having a higher pressure than the first gas to the dry pump; a valve portion that opens or closes the first line and the second line; and a control unit that controls opening or closing of the valve portion.

Claim (Index 3):
The laser machining device according to  claim 1 , wherein the valve portion includes:\n a first stop valve that opens or closes the first line; and a second stop valve that opens or closes the second line, and the control unit opens the first stop valve and the second stop valve to supply the first gas and the second gas to the dry pump from the first line and the second line, respectively, and closes the second stop valve after the elapse of a predetermined period.
