What is the adjustment method of the line thickness of the laser marking machine?
With the continuous advancement of pneumatic marking technology, the price of laser marking machines is gradually decreasing, because laser marking machines have good marking results and high power. In order to improve work efficiency, many small and medium-sized enterprises have replaced laser marking machines. It is true that the laser marking machine had a large number of users at the beginning, but the operators of many companies have not received training, so it is easy to cause the laser marking machine to malfunction due to operating errors. Moreover, they will not debug and eliminate equipment failures.
Frequent users often ask about the operation of the laser marking machine. For the convenience of everyone, especially the use skills and debugging methods of the laser marking machine are explained to you. First, let's take a look at how the laser marking machine adjusts the thickness of the line. \
What does the line thickness of the laser marking machine have to do with? This problem is currently a problem that many customers want to understand, and many people consult. The following will explain to you in detail on this issue.
1. To adjust the line thickness of the laser marking machine, the first thing to consider is the divergence angle of the beam, which is the basic reason on the optical principle. The beam divergence angle means that the beam propagates through divergence. The divergence angle is a measure of the divergence. The divergence angle is 0. This is the ultimate goal of our industry. But in fact, we can only make the divergence angle close to zero infinitely, but it is not yet possible to make the divergence angle zero.
If it is true parallel light, after passing through the focusing lens, the parallel light will be concentrated on a point, which is a straight infinitely small point. But because of the real parallel light in the world with a divergence angle of 0, we have no choice but to achieve an infinitely small point. The focal point has a size, which is proportional to the line marked by our marking machine. Therefore, the beam expander is an optical element that we use to tighten the divergence angle of the beam. When the multiple of the beam expander is larger, the divergence angle of the beam becomes smaller, and vice versa.
Second, consider the function of the laser marking machine itself. The divergence angle of the instrument with a good spot pattern is small, and the divergence angle of the instrument with a poor spot pattern is large. This is why the laser marking machine does not need a beam expander, but the laser marking machine needs to use it. Of course, when our customers choose laser marking machines, the quality of the equipment is very important.
Third, the factor to be considered is the interaction between the beam and the matter. When the same marking machine marks different materials, the line precision is naturally different. In addition, the energy used is also different, which will also cause the thickness of the marking line to be different.
