How to mark the laser cutting machine tool?

How does the laser cutting machine carry on the marking operation ? Let's discuss the problem today. In fact, the laser cutting machine marking principle and cutting principle is the same. The difference between them is that the cutting energy is greater, and can cut through the steel plate, while the marking energy is smaller, leaving only marks on the surface of the steel plate. If you want to do both cutting and marking, you can follow these steps.

Because marking and cutting use different energy, it is necessary to set two different sets of parameters for marking and cutting at the same time.

First, box the markup section and set it to a different color processing layer .

Then, check the process parameters. As you can see, there will be an additional set of process parameters with the same color as the font. Just adjust the parameters according to the actual situation. If a highly reflective material is used, black spots will appear at the corners. At this time, the focal power of the curve can be adjusted to solve this problem.

It should be noted that the width of the marker font is actually determined by the projected width of the laser beam, which is also affected by the height of the nozzle and the size of the focus. However, the size of both influences the energy density. The depth of the lettering actually depends on the degree to which the laser energy is burned on the surface of the material, which is also affected by the laser power and duty cycle. The higher the laser power and duty cycle, the deeper the trace, but if the trace is too high, it is prone to excessive burning or blackening. In the marking process, you can use air, oxygen or nitrogen and other gases.
