Laser machining device |
摘要 |
In a laser machining apparatus comprising a deflector for changing a direction of a laser beam outputted from a laser oscillator, and a converging lens for refracting the laser beam introduced from the deflector and focusing the laser beam onto a work to be machined, a lens position adjusting unit is provided for changing a relative position between a plurality of lenses constituting the converging lens and the lens position adjusting unit change the relative positions of the lenses so as to cancel a change in refractance of the lenses due to a change in the temperature.
