How to clean the lens of laser cutting machine correctly?

The lenses used in the laser cutting machine are divided into many kinds of aggregation lenses, protective lenses, etc. In the course of their work, they will inevitably be subject to some pollution, such as water pollution  dust pollution, etc., then the daily maintenance process requires laser The lens is cleaned to ensure the stability of the laser cutting machine. Of course, cleaning lenses is  like cleaning spectacle lenses in our lives. Special attention is required.

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

1. Use a blower to blow off the floating objects on the surface of the original, especially the lens with fine particles  flocs on the surface, this step is necessary. But do  use compressed air on the production line, because the air will contain oil mist  water droplets, which will deepen the pollution of the lens.

2. Use analytical acetone to clean the lens. This level of acetone is almost anhydrous, which reduces the possibility of lens contamination.

If the cotton ball is dipped in acetone, it is necessary to wash the lens under light  move in a circle. Once the cotton swab is dirty, it is necessary to replace it. The cleaning should be completed at one time to avoid the occurrence of ripples.

If the lens has two coated surfaces, such as lenses, each face needs to be cleaned in this way. One side needs to be placed on a layer of clean lens paper for protection.

3. If acetone cannot remove all the dirt, then use acid vinegar to clean. Sour vinegar is used to dissolve the dirt to remove the dirt, but it will  cause damage to the optical lens. This vinegar can be experimental grade (diluted to 50% strength),  white vinegar with 6% acetic acid for household use. The cleaning procedure is the same as acetone cleaning,  then use acetone to remove the acid vinegar  dry the lens. At this time, the cotton ball must be changed frequently to completely absorb the acid  hydrate. Until clean.

4. When the pollutants  lens damage cannot be removed by cleaning, especially the film burnout caused by metal splashes  dust, the first way to restore good function is to replace the lens.

In the process of cleaning the lens, the only purpose is to remove the contamination of the lens,  do  cause further contamination  damage to the lens.

In the installation  cleaning of the lens, any sticky substance  even oil drops on the nail print will improve the absorption rate of the lens  reduce the service life.

Therefore, the following precautions must be taken:  

1. Never use naked fingers to install lenses. Finger gloves  rubber gloves should be worn.  

2. Do  use sharp instruments to prevent scratches on the lens surface.  

3. Do  touch the film when taking the lens, but hold the edge of the lens.  

4. The lens of the laser cutting machine should be placed in a dry  tidy place for inspection  cleaning. A good workbench surface should be cleaned with a rare layer of paper towels,  a rare sheet of lens tissue.  

5. Users should prevent speaking above the lens  keep food, drinks  other potential contaminants away  the working environment.

Note: Of course, certain contaminants  lens damage cannot be removed by cleaning, especially the film burnout caused by metal splashes  dirt. The only way to restore outstanding function is to replace the lens.

Correct installation method In the installation process, if the method is  correct, it will cause the lens to be contaminated. Therefore, the operating procedures mentioned earlier should be strictly observed.

When the lens is properly cleaned  operated, its service life  performance will undoubtedly be significantly improved, which is also one of the important ways to improve the life  stability of the laser cutting machine. Taking some precautions  maintenance methods will ensure that the laser cutting machine works longer  has higher stability.
