Laser engraving machine failure phenomenon: when the cleaning process at the bottom of the phenomenon of a clear, cloudy appearance for carving any when there is cross-formation phenomenon is not clear; Yang carved, the words in between words and non-obvious process line, the more clean-up depth, the more obvious phenomena.
Fault reasons:
1, fast processing speed, response speed can not keep up the laser tube.
2, laser control of the switching frequency is too low, the laser line is too long, not point-like beam, resulting in tailing phenomenon.
3, the flow is not blowing, causing adhesion of powder processing, the formation of line processes.
4, optical path is not partial or focal length, resulting in scattering beam, caused by uneven bottom.
5, focusing lens choice is unreasonable, should be advised to select a shorter focal length lenses to improve the beam quality.
Laser engraving machine troubleshooting methods:
a, first check the optical path, and ensure the correct optical path.
b, lower processing speed, increase the switching frequency of the laser output.
c, the air conditioning blowing good to ensure that no powder adhesion, side-blown as far as possible.
d, choose a short focal length lens, focal length adjustment shall give due consideration to the depth of processing. |
