The Main Points Of Maintenance And Cleaning Of Optical Fiber Laser Cutting Machine Lenses

Optical lenses of optical fiber laser cutting machines are consumables. In order to extend the service life and reduce the cost of use as much as possible, we must strictly standardize maintenance and cleaning lenses. After a new lens is settled, it should be cleaned regularly. Of course, cleaning the lens should not be like cleaning glasses, you must pay more attention. If it affects the cutting effect, you need to replace the lens in time. During the replacement process, the placing, detection, and installation of optical lenses should be paid attention to damage and pollution.
Lens replacement situation:
If there are no professional operation cleaning, if you are worried about secondary pollution or damage lenses during the cleaning process, you can ignore the cleaning steps. It is recommended to replace the lens directly. Performance, the only way is to replace the lens.
Key points for lens cleaning:
During the laser cutting process, when the pollutant falls on the surface of the lens, it will absorb energy from the laser beam, resulting in the thermal lens effect. If the lens has not formed a thermal stress, the operator can disassemble and clean it.
The main points of contact of NO.1 lens:
During the installation and cleaning of the lens, any adhesive, even nail printing or oil droplets will increase the absorption rate of the lens and reduce the service life.
Under normal circumstances, the following preventive measures are adopted:
1. Do not install the lens with naked fingers. Bring a finger cover or rubber glove.
2. Do not use a described equipment to avoid scratching the surface of the lens.
3. Do not touch the membrane layer when taking the lens, but hold the edge of the lens.
4. The lens should be placed in a dry and tidy place to detect and clean. There should be several layers of paper towels on the surface of a good workbench, and several cleaning lens cotton paper.
5. Users should avoid speaking above the lens and let food, drinks and other potential pollutants stay away from the working environment.
Method of cleaning the lens:
During the process of cleaning the lens, the relatively small risk method should be adopted. In order to minimize the risk, sort out the following points:
1. First of all, the air balloon is used to blow off the floating objects on the surface of the component, especially the lenses with tiny particles and floccope on the surface. Oil and water droplets will deepen the pollution of the lens.
2. The second step is to use acetone to lightly clean the lens. This level of acetone is almost waterless, which reduces the possibility of lens pollution. Cotton balls are dipped in acetone and must be cleaned under light and move ring -shaped. When the cotton swab is dirty, it must be replaced. Washing must be completed at once to avoid turbulence. (If the lens has two coating surfaces, such as a lens, each side needs to be cleaned in this way. The first side needs to be placed on a clean lens paper to protect.)

3. If the acetone cannot remove all the dirt, then wash it with sour vinegar. Sour vinegar cleaning uses the dissolution of dirt to achieve cleaning dirt, but it does not cause damage to optical lenses. This acetic acid can be an experimental level (diluted to 50%intensity), or the white vinegar used for 6%of the family can be used. The cleaning program is the same as the acetone cleaning, and then use acetone to remove the acid vinegar and dry the lens. Until cleaning.
4. When pollutants and lens injury cannot be removed by washing, especially the film layer caused by metal splashing and dirt burns. To restore good performance, the only way is to replace the lens. Try to wear gloves or fingers when replacing the lens to prevent pollution lenses.
Note: During the installation process, if the method is incorrect, the lens will be contaminated. Therefore, the operating procedures mentioned above must also be complied with. A clear improvement, this is also one of the important ways for the life and stability of the laser cutting machine. Adopting some preventive and maintenance measures can ensure that the laser cutting machine is working longer and higher stability.
