As we all know, one of the most important components of fiber laser cutting machine is the laser cutting head with high precision and high price.
The life of the laser cutting head not only affects the working efficiency of the cutting machine, but also affects the production cost and the benefit of the factory.
In addition, the most common problem affecting the life of the cutting head is the pollution damage of the optical lens inside the structure.
Today, we will teach how to maintain the optical lens of the laser cutting head.
How to maintain the lens of optical fiber laser cutting machine?
Possible causes of lens contamination of laser cutting head
1. The optical fiber head in the cutting head is installed incorrectly.
Therefore, the main solution is to choose the correct installation method of optical fiber laser head.
Most installers tend to assemble the cutting head freely, so as to tilt the installation direction of the optical fiber head, resulting in careless installation.
We should try to install the fiber head horizontally inside the cutting head and lock it during installation.
In addition, we can try to operate in a clean environment to avoid raising dust during installation.
Or we can choose to operate in the morning to prevent dust from entering the cutting head.
2. Poor sealing effect of cutting head
Then, it is feasible to install a ventilation system to maintain the internal pressure of the cutting head.
3. Incorrect replacement of protective window box
Due to the large volume of the protective mirror box, particles will inevitably be mixed in the replacement process.
Therefore, the speed must be changed when replacing the protective mirror box. We should seal the windows with tape or other film.
4. Use of unreasonable cutting head consumables
Selecting qualified protective glasses and “O” type sealing rubber ring can ensure the sealing of cutting head and prevent dust from entering.
5. Improper operation of laser cutting machine
When operating the laser cutting machine, we must strictly follow the equipment instructions and requirements and operate correctly. Reduce the impact of incorrect handling on the cutting head.
6. Poor maintenance of cutting head
The cutting head shall be clean and dry as much as possible and cleaned regularly.
