Abstract
A laser machining apparatus that excels in precision in terms of machining position and shape is provided with an optical axis adjusting unit disposed on a basal optical axis of a laser beam outputted from a laser oscillator so as to adjust the laser beam outputted from the laser oscillator onto a workpiece. The laser machining apparatus is provided further with mirrors, disposed between the laser oscillator and the optical axis adjusting unit, for freely deflecting the optical axis of the laser beam. The laser machining apparatus also includes an optical axis position detecting means, disposed between the optical axis adjusting unit and the optical axis deflecting means, for detecting the position of the optical axis of the laser beam. The apparatus aligns the optical axis of the laser beam incident on the optical axis adjusting unit with the basal optical axis by means of the mirrors based on a result detected by the optical axis position detecting means.
