Problems solved by technology

The stability of the external optical path system has a great influence on the laser processing, and limits the processing efficiency to a certain extent
[0004] For the drilling of the workpiece, the traditional laser processor has a large divergence angle after focusing, and the collimation degree is reduced, so the hole wall will have a certain inclination angle. Although the rotary drilling solves the problem to a certain extent The problem of verticality, but its processing efficiency is low and the stability is not high
[0005] Therefore, traditional laser processors have the disadvantages of low processing efficiency and poor stability for complex components

Embodiment 2

[0066] The same part as embodiment 1 will not be repeated, and the difference is:

[0067] The present invention also provides a method for laser processing using the above-mentioned laser processing system, comprising the following steps:

[0068] (1) if figure 2 As shown, according to the needs of processing, adjust the position of the first fixed frame 4 and the second fixed frame 5, determine the optical path length z, after setting, in the process of processing, the first fixed frame 4 drives the laser head 3 along the second guide rail 14 While moving, the second fixed frame 5 moves in the same direction as the laser head 3, and moves at 1 / 2 speed of the laser head 3 to ensure that the constant optical path length z is maintained during the movement of the laser head 3;

[0069] (2) After the laser light output by the laser device 2 is reflected by the mirror 6 in turn, the laser light is introduced into the laser head 3 to obtain the incident light beam 8;

[0070] (...
