ABSTRACT:
A laser machining apparatus comprises a first, a second and a third mirror for turning the direction of a laser beam, which are provided in between a machining head for irradiating a workpiece with the laser beam and a vertical Z-axis drive for moving the machining head in the vertical direction. The laser machining apparatus further comprises first drive means for varying the relative position between the first mirror, and the second and third mirrors by moving the relative position in the direction in which the laser beam proceeds from the first mirror to the second mirror, and second drive means for varying the relative position between the second and third mirrors by moving the relative position in the direction in which the laser beam proceeds from the second mirror to the third mirror.
