Influencing factors and improvement of engraving depth of laser marking machine

There are two important technical indicators of Laser Marking Machine in the application: marking depth and marking width. What are the adjustment factors that influence the engraving depth of the laser marking machine?

1. Direct adjustment method: Increase the power of the laser: Everyone knows that the laser is the core component of the laser marking machine, just like the engine of a car. As the quality of the laser is improved, the laser beam is bound to be improved.The cost of the whole machine will increase,but the effect is definitely immediate. Another point is that once the laser is upgraded, its corresponding supporting devices must be upgraded, so the cost of the machine will increase.

2. Change the lens of the laser marking machine into a small-scale lens. After the transformation, the marking depth will be deeper. For example, the previous semiconductor laser marking machine can be equipped with a lens of 110, which becomes with a lens of 50, the total laser energy and lettering depth will be about twice as high as before. The same is true for the popular fiber laser marking machine now.

3. Improve beam quality. It is necessary to adjust the interior of the laser cavity, replace the light guide material or replace the pump source or improve the laser total reflection mirror and output mirror. For example, in the case of a semiconductor laser marking machine, small holes are added to increase the cooling accuracy, and the laser mode is adjusted to emit light, so that the laser is large, round and bright. In short: it is to improve the configuration of the laser cavity. We need to understand the structure and configuration of the laser marking machine, otherwise it will directly affect the equipment.

4. Slow down the marking speed of the laser marking machine. Under the same power and the same other parameters, just modify the marking speed, and the marking depth will be deeper. That is to say, the speed is slowed down, the power is increased, and the depth is deeper.

5. Replace high-quality laser marking accessories and use high-quality laser groups. It is a good way to use a beam expander to process the light spot, which can enhance the focusing degree of the laser, and the obtained light spot effect is also ideal.

We know that the overall configuration, performance, etc. of the laser marking machine are not the same as the merchants think. A small detail, simple configuration will directly affect your marking effect, which may lead to high loss of accessories, it is also possible to extend the lifespan.

Feiquan laser marking machine consumes less power and is easy to operate. The theoretical life of the fiber laser is 100,000 hours, and the operating life is super long. It is a new type of environmentally friendly and energy-saving laser marking equipment.
