How to adjust the marking depth of laser marking machine

Posted by sere on March 10th, 2020

During the operation, the selection of different parameters and different marking materials of the material will affect the marking depth of the laser marking machine, and sometimes the marking effect is too shallow or too deep. In fact, the lettering depth of the laser marking machine can be For a certain degree of adjustment, the main adjustment methods are as follows for your reference;

If the marking effect is not deep enough, you can slowly increase the power of the laser coder until the appropriate depth is achieved. This is the most direct adjustment method.

If the above method is not effective, then the marking speed of thelaser coding machine is slowed down. Under the same power and the same other parameters, only the speed of the marking will be modified to deepen the marking depth.

Another method is to change the field lens of the laser coder into a small field lens. After the conversion, the depth of marking will be deeper. For example, the current semiconductor laser marking machine can wildly use the field lens of 110. , Becomes a field lens of 50, its total laser energy and lettering depth will reach about 2 times the effect.

If the field lens has no obvious effect after adjustment, you can consider replacing the imported field lens to make the marking lettering deeper. For example, the semiconductor laser coder uses a German lens, and the CO2 lens uses a U.S. uniform head, which can guarantee a certain depth.

If the laser mode of the laser marking machine becomes better, the marking depth will also be improved to a certain extent. For example, if a semiconductor laser marking machine is used, a small hole is added to increase the cooling accuracy. , The roundest, the brightest.

If it still does n’t work, then you have to replace the laser with a more successful land-type laser, directly increase the depth of the engraving of the laser printer, and replace the better laser marking accessories, such as semiconductor laser marking machine The imported Q switch will have better marking depth.
