The reasons and solutions for the uneven depth of marking images and texts in laser marking machines

1. The lens has stains or scratches
Solution: If there are stains, you can use a cotton swab and alcohol to wipe the lens, beam expander, and focusing lens, wiping off the surface material. Remember not to use hard objects to wipe the lens; If there are scratches or other damages on the lenses, the only option is to replace the marking machine lens.

2. There is a deviation in the optical path
Solution: If the optical path deviates, simply readjust the optical path.

3. Excessive marking speed and unreasonable filling method
Solution: Reduce the marking speed, adjust the original filling method, and make sure that the workpiece is on top. Adjust the focus again.

4. The current problem of the marking machine
Solution: If the current of the device's power supply is too small, it can also affect the depth of the marked text. At this time, it is necessary to increase the current of the laser power supply, reduce the frequency of the marking machine, so that the marking machine can operate normally and avoid the situation where the marked text is too shallow.
