What Problems Do You Usually Encounter When Using A Laser Marking Machine?

During the use of laser marking machines, you may encounter the following common problems:

1. The laser does not emit light: This may be caused by the fact that the laser power is not turned on, the laser is damaged, the potentiometer for adjusting the current is in poor contact, etc. It is necessary to check whether there are any problems with the power supply, circuit, optical path, etc., and make corresponding repairs or replacements.
2. The position of the marking mark is inaccurate: it may be caused by incorrect clamping position of the workpiece, deviation of the position of the laser head aiming at the mark, excessive marking speed, etc. It is necessary to correctly install the workpiece, adjust the alignment mark position of the laser head, and adjust the marking speed.
3. Burning phenomenon occurs during the marking process: it may be caused by excessive adjustment of the laser power, oil stains or oxide layers on the surface of the workpiece, or too close distance between the laser beam and the workpiece. It is necessary to adjust the laser power, clean the workpiece surface, and adjust the distance between the laser beam and the workpiece.
4. Intermittent or skipping phenomena occur during the marking process: it may be caused by the marking speed being too fast, the laser power adjustment being too small, oil stains or oxide layers on the surface of the workpiece, etc. It is necessary to adjust the marking speed, adjust the laser power or clean the workpiece surface.
5. The focus is not adjusted properly: Readjust the focus.
6. The marking software method is not selected: Select the correct marking software method.
7. The cavity, total reflection mirror, half-reflection mirror and beam expander are not adjusted properly: readjust them.
8. The laser does not hit the center of the galvanometer, or the lens of the galvanometer is scratched: readjust the light path or replace the galvanometer.
9. Totally reflective or semi-reflective lenses, focusing lenses, galvanometer lenses, and Q-switch lenses are dirty or scratched: clean them or replace them.
10. The Q switch is not adjusted properly: The Q switch needs to be adjusted.
The above are the problems that may be encountered during the use of laser marking machines. If the above problems occur, you can refer to the above solutions. If not, you can contact professional technicians for help.
