The cutting quality and precision of the CNC laser cutting machine are very high, and there may be no light in the process of use. If it is in production, please turn off the laser cutting machine first. If this kind of failure occurs, don't panic. Usually the laser does not light The reasons are as follows: 1. The aging of the laser tube causes insufficient laser power. 2. The output current of the laser is low because the current is low. 3. There is more dust in the laser, which masks the diaphragm mirror, causing opacity or poor light transmission. In short, the situation that the laser does not emit light occurs from time to time. It needs to be treated in specific situations, and the source of the problem should be found and dealt with accordingly.

Method to solve the problem that the laser does not emit light

In response to the above-mentioned problem that the laser does not emit light, we only need to carry out an inspection step by step, and timely find out why the laser cutting machine does not emit light, and we can resume production. First, check whether the water cycle is normal. Water protection is an easy part for many people to forget when operating a laser machine. If there is a problem, pay attention to it. In addition, pre-adjust the point to see the swing of the ammeter. If it does not move, the power supply may be faulty. Whether it is swinging or not, it may be a power failure. The problem of low laser power can be solved by replacing the laser tube. The light path is not correct, it may be due to the looseness of the light path screws. You can readjust the light path. The problem of diaphragm mirrors can be solved in many ways, cleaning the diaphragm holder with absolute ethanol, or using a new diaphragm. Turning off the power of the machine tool for a period of time and then turning it on can effectively solve the icing phenomenon caused by the long-term operation of the cooling system.

The above can effectively solve the problem that the laser cutting machine does not emit light. During the production process, if the laser does not emit light, you can refer to the above methods for troubleshooting, or call Suzhou Laser Engraving Machine directly after sale.
