If there is water mist, oil or other things on the lens of the laser tube cutting machine, it will affect the cutting effect of the tube, and the quality of the processed product will not meet the expected standards. So how should we clean the dirty lens?

Five precautions to know before cleaning the lens

1. Before removing the protective lens, turn off the surrounding wind source to prevent the airflow from bringing dust into the cutting head when removing the protective lens, causing internal pollution. And pay attention to the cleaning around the protective lens window of the cutting head.

2. When taking the lens, do not touch the film layer and the mirror surface with your hands. You should pinch the edge of the lens and place the lens on the lens paper.

3. Do not talk directly to the lens, and keep all pollutants away from the working environment as much as possible.

4. When cleaning the lens, try to operate in a dust-free environment. You can use anhydrous ethanol and other detergents to clean it, and then wipe the lens with a dry cotton cloth to make the lens bright and transparent.

5. When installing the protective lens, be sure to wear powder-free gloves or rubber gloves. Do not install the lens with bare fingers, otherwise fingerprints will be left on the lens.

Three ways to clean the lens:

1. For lenses with dust on them, we can perform soft cleaning, and use an air bag or cleaning air to blow away the scattered pollutants on the lens surface.

2. You can also try to perform soft cleaning on lenses with stains and fingerprints. You can soak an unused special front with a cleaning agent such as acetone or anhydrous ethanol, gently wipe the surface of the lens, and slowly drag the wet cotton on the surface of the lens so that the liquid left behind the wet cotton can evaporate immediately.

3. For lenses with oil on the lens, you can perform medium-intensity cleaning. Soak an unused cotton swab with 6% distilled white vinegar, wipe the surface of the lens with slight pressure, wipe the excess distilled vinegar on the surface of the lens with a clean dry cotton swab, and then soak a cotton swab with acetone and gently wipe the surface of the lens to remove all acetic acid.

If the above methods cannot completely clean the lens, it is recommended to replace the lens with a new one in time to ensure the cutting quality.
