ので精度の高い加工が可能となるのである。By the way, the laser beam output from the laser beam oscillator (1)
Generally, the laser beam (1) incident on the condenser lens (3) is not necessarily perpendicular to the condenser lens (3) because it is reflected by a plurality of pend mirrors and guided by the condenser lens (3) 1. Instead, it will be incident at a certain angle. If processing is carried out in this state, it will have an adverse effect on the processed camphor fabric, as described above. Therefore, the processing head of the laser processing machine according to the present invention uses a laser beam (
1) Inject the light into the condenser lens (3) at a tilted angle.
Move the condenser lens (8) in the t-X-Y direction! 0 to adjust the incident angle of the laser beam (1). That is, as shown in FIG. 5, the laser beam (1) is incident on the optical axis (1a) at a certain angle θ with respect to the center (3a) of the condenser lens (3).
is the angle of incidence θ of seven! 1, the focus will be focused at position A1, but for example, if the condenser lens (3) is moved to the position shown by the broken line in the full diagram, the optical axis will be moved to position 1b''#, even though the incident angle θ is the same. vJ-r, the focal point also moves to the position A2 on the optical axis (1b).As a result, the workpiece (
6) is irradiated with laser light (1) without any inclination. On the other hand, if the center of the laser beam (1) and the center of the nozzle (4) can be aligned after adjusting the inclination of the V laser beam (1) as described above, the nozzle IV adjustment means (10 ) can be adjusted by moving the nozzle (4) in the X-Y direction using the adjustment screw (11). In this way, the laser beam (
When laser processing is performed using a processing head whose inclination in 1) and nozzle/I/(4) position are adjusted, the laser beam (1)
is irradiated onto the workpiece (6) without tilting, and the assist gas injected from the laser beam passage port (5) of the nozzle (4) also covers the entire processed area uniformly. Therefore, highly accurate machining is possible.
