How To Use Fiber Laser Cutting Machines To Save Protection Lenses

Everyone is familiar with the laser cutting machine. As the thickness of the processing metal plates gradually increases, the application of thousands of tiles of laser cutting machines is becoming more and more extensive. Users often ask why the protective lenses of laser cutting heads during the operation of laser cutting machines have a burning phenomenon in the laser cutting head. Essence So, what causes the laser cutting head protection lens burning? How to effectively prevent the protective lens burning? Let ’s take a look at Qingyuan Laser.
Laser cutting header lens function:
Protective lens is a very important precision component in the light road system of the laser cutting machine. The laser cutting head will gather a large amount of energy during processing. In order to block the dust and slag splashes, protect the internal light path and core components of the laser cut head. Therefore The lens, effectively protects the laser cutting head is not damaged.
What are the reasons for protecting the lens?
The protective lens of the laser cutting machine is prone to burning. Most cases are due to improper equipment maintenance. For example, dust pollution in the lens has not stopped light in time, the temperature of the protective mirror is high, and there is water. Laser light road offset, cutting nozzle pores, large -scale protection lenses, collision with other items, etc., will affect the protective lens. It is easy to cause the lens to burn or rupture.
The protective lens of the laser cutting machine is consumed and easy to be damaged, and generally needs to be replaced in time. When the power is increased to more than 10 watts, once the dust is polluted on the lens, it does not stop it in time to prevent the burning point from worsening. The energy absorbed instantaneous increases, it is easy to explode. The protection lens is in high temperature state, and if there is water on the lens, there is a possibility of bursting.
Main reason:
1.The process parameters do not match the thickness of the board;
2.Dust;
3.The elasticity of the cut head spring is weak or fixed, which causes the cut head bias;
4.The process parameters match the thickness of the board, but the air pressure, cutting speed and power do not match;
5.Gas liquefaction speed is too slow to keep up with the speed of use.
