Laser marking machine frequency and speed

Updated Apr. 02, 2022

Laser marking machine frequency:
The number of pulses per unit time is called the marking frequency of the fiber laser marking machine. This is a good understanding. When the marking frequency is large, the laser spot is dense, and if the marking frequency is small, the laser spot is loose. Although the naked eye may not feel it, if we put the marking place under the electron microscope, we can see through the enlargement that it is a continuous line in the eyes that is composed of many points. The higher the marking frequency, the denser the laser spot and the smoother the marking.
Laser marking machine speed:
This refers to the scanning galvanometer speed of the laser. This speed is the speed that can be adjusted in the parameters, not the overall speed at which a product is marked. Because the overall marking speed is not only affected by the adjustment of the speed parameters, but also by the marking depth, marking area and other factors. Marking speed The role of this parameter is that the faster the other conditions are, the faster the marking speed will be. The speed is fast, and the number of times the laser is struck in the same place is less. Slow speed is more conducive to depth. But it is not the slower the speed, the better the depth. Because the speed of the marking is too slow, the material that the laser hits will accumulate on the surface of the material, affecting the laser to hit deeper. So if you are playing depth, you should use a high speed sweep after a few times at low speed.
