How to adjust laser marking machine parameters to achieve deep marking

To achieve deep marking, we can adjust the parameters of the laser marking machine through the following methods:

1. Adjust the focal length
Reduce the focal length to the minimum to ensure that the laser beam can be accurately focused on the surface of the material, thereby achieving the goal of deep marking.

2. Adjust the laser power
Laser power is the core factor affecting the depth of marking. We need to ensure that the power is set appropriately, neither too high to cause excessive focus or material damage, nor too low to make the marking effect insignificant.

3. Adjust the marking speed
Marking speed too fast may prevent the laser from penetrating the surface of the object, while too slow may cause the laser to stay on the surface of the object for too long. Therefore, it is crucial to adjust the marking speed appropriately.

4. Transform the field mirror
Using a small-scale field lens can help improve the depth of the marking.

5. Replace the field lens or laser
If conditions permit, replacing with higher quality field mirrors or choosing higher power lasers can further deepen the depth of the marking.

6. Adjust the laser mode
Adopting better laser modes, such as pulse marking mode, can further enhance the depth of marking.
