Reasons for shallow engraving depth when laser marking machine is working

How to solve the problem of shallow engraving depth when the laser marking machine is working? Laser marking machine uses laser beam to mark the surface of various materials for a long time. The effect of marking is to expose deep substances through evaporation of surface substances, or to "carve" traces through chemical and physical changes of surface substances caused by light energy, or to show patterns and characters to be etched by burning some substances with light energy. When the laser marking machine is used, the laser is weak and the laser engraving depth of the product is shallow. This problem is generally caused by improper operation.

Reasons for shallow engraving depth when laser marking machine is working

Reasons and solutions for shallow engraving depth when the laser marking machine is working:

1. Deviation of optical path
If this happens, it is necessary to re light the light path adjustment to restore it to the best state; The marking speed of the marking machine is too fast, and the filling method is unreasonable. This will slow down the marking. Adjust the original fill method. In addition to determining whether the workpiece is at the top, the focus is on readjustment.

2. The lens is dirty with stains
This problem is solved naturally by using only some cotton swabs and some alcohol, and then scrubbing the marking machine lens, beam expander and focusing lens to remove the stains on them.

3. Problems with the marking machine
If the power current of the device is too small, it will also affect the depth of the marking words or patterns, then increasing the laser power current will reduce the frequency of the marking machine, so that the laser marking machine can operate normally and avoid too shallow characters; The marking machine is suitable for marking and engraving of metal and non-metallic products.
