How to maintain the optical lens of laser cutting head?

As we all know, one of the most important components of the fiber laser cutting machine is the laser cutting head with the characteristics of high precision and high price.

The life of the laser cutting head does not affect the operating efficiency of the cutting machine, but also the production cost and benefits of the factory.

What’s more, 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.

The possible reasons of lens contamination of laser cutting head

1.The fiber head installation method is incorrect in the cutting head.

For this reason, the main solution is to choose the correct fiber laser head installation method.

Most installers tend to assemble freely the cutting heads, tilting the fiber-optic head installation direction, resulting in inadvertent installation.

We should try to keep the fiber head horizontally installed inside the cutting head and lock it during the installation process.

Besides that we can try to operate in a clean environment avoid dust from rising during the installation process.

Or we can choose to operate in the morning to prevent dust from entering the cutting head.

2.The cutting head itself has a poor sealing effect

For the sealing of the cutting head, it is not always possible to guarantee complete sealing.

Then, a feasible method is to install a breathing system to maintain the internal pressure of the cutting head.

3.Incorrect replacement of the protective window case

Due to the relatively large volume of the protective mirror box, particles are inevitably mixed during the replacement process.

Therefore, we must change the speed  when replacing the protective mirror box.

And we should seal the window with tape or other film.

4.Unreasonable cutting head consumables used

The selection of qualified protective mirrors and “O” type sealing rubber ring can ensure the sealing of the cutting head and prevent the entry of dust particles.

5.Improper laser cutting machine operation

When operating the laser cutting machine, we must strictly follow the equipment instructions and requirements and operate correctly.

Reduce the impact of improper handling on the cutting head.

6.Poor maintenance of the cutting head

The cutting head should be as clean and dry as possible and cleaned regularly.
