How to solve the different marking depth of laser marking machine

The laser marking machine has two important technical indicators when processing products, one is the width of the marking, and the other is the depth of the marking. Let me analyze the adjustment method of the laser marking machine with you

Laser marking machine

1. Improve the beam quality of the laser marking machine: we need to adjust the inside of the laser to replace the pump source or Light guides, etc. Or upgrade the laser output mirror and the laser total reflection mirror. For example, for semiconductor laser marking machines, we can increase the cooling accuracy and adjust the laser beam. In short, we must understand the structure and configuration of the laser marking machine before dealing with the problem.

2. Improve the power of the laser: The laser is the core component of the laser marking machine, its quality directly affects the quality of our marking, replace the good laser or increase The power of the laser makes it have higher work efficiency. Although the cost is high, the effect is immediate.

3. Reduce the scope of the scene: We change the field lens of the laser marking machine into a field lens with a small range, and the marking depth will also be reduced after the field lens becomes smaller. It will be deeper. For example, the previous semiconductor laser marking machine can be equipped with a field lens of 110, and it becomes a field lens of 50. The total laser energy and lettering depth will be about 2 times the previous effect. Similarly, the fiber laser marking machine can also operate in the same way.

4. Slow down the marking speed : Under the same speed and power, we can slow down the marking speed and increase the depth of reaching the standard. If you are pursuing high output, this method is not recommended.

5. Upgrading accessories: we can upgrade the better laser group with better light concentration
