After using the metal laser marking machine for a period of time, the marking effect will be unclear. Why is the metal laser marking machine's marking font not clear? How should it be solved?
1. The use time is too long. The service life of any metal laser marking machine is limited. After a certain period of time, the laser intensity will decrease, resulting in unclear marking.
Solution: First, pay attention to the regular operation and daily maintenance of the metal laser marking machine. The service life of some metal laser marking machines will be shorter, and some will be longer. The user is using the impact of operation and maintenance. Second, when the metal laser marking machine reaches the end of its service life, it can be solved by replacing the laser module.
2. Operational problems. It may be that the marking speed is too fast and the laser power current is too small.
Solution: If the marking speed is too fast, you can reduce the marking speed, thereby increasing the density of the filling. If the power supply current of the laser is too small, you can increase the power of the power supply current appropriately.
3. The equipment problem. Such as field lens, galvanometer, laser output lens and other equipment problems. The field lens is too dirty, which affects the focus, the vibrating lens is unevenly heated, or the film of the vibrating lens is damaged, and the laser output lens is contaminated.
Solution: When the metal laser marking machine is produced, an exhaust fan should be used to prevent pollutants from fretting the lens. It is best to seal the galvanometer system to prevent the ingress of moisture and dust. If there are some lenses that cannot be wiped, you can send them to a professional manufacturer to solve them.
