When the laser cuts the material, the work surface releases a large amount of gases and splatters that will harm the lenses. When contaminants fall on the surface of the lens, they will absorb energy from the laser beam, resulting in a thermal lensing effect. If the lens has not developed thermal stress, the operator can disassemble it and clean it. Any bit of sticky material during the installation and cleaning of the lenses will cause the lenses to absorb more and reduce their service life.

Laser cutting machine used in the lens is divided into many kinds of focusing lens, protective lens, etc., in its working process will inevitably be subject to some pollution, such as water pollution or dust pollution, etc., in order to extend the service life of the laser cutting machine as much as possible to reduce the use of cost, then the daily maintenance process needs to be cleaned and processed on the laser lens, in order to ensure the stability of the laser cutting machine.

 The correct cleaning of the laser cutting machine lens operation steps are as follows:

1. Blow off the floating material on the surface of the original part by blowing a balloon. Do not use compressed air from the production line, because this air will contain oil mist and water droplets, which will deepen the contamination of the lens.

2. Use analytically pure acetone to gently clean the lenses. Cleaning should be done in one go to avoid wavy bands.

3. If acetone cannot remove all the dirt, then use acid vinegar to clean.

4. When contaminants and lens damage cannot be removed and removed, the only way to restore good performance is to replace the lens.
