The cleanliness of the lens of the laser cutting machine directly affects the processing function and quality of the laser cutting machine, and regular maintenance of the lens is very necessary.
The following are the lens maintenance steps of the metal laser cutting machine:
1. Disassemble the focusing lens: loosen the screws first, and then remove the air nozzle and lens barrel one by one. Then use a blower to remove dust from the mirror.
2. If the laser cutting head needs to be cleaned, it is recommended to use a laboratory-grade soft cotton ball, dipped in an appropriate amount of alcohol or acetone, and rotate clockwise from the center of the lens to the edge.
3. After cleaning, put the air nozzle, lens barrel and other accessories back to their original positions in sequence, adjust the proper focal length, and reinstall the removed screws. When installing the focusing lens, be sure to make the convex side face down.
What should be paid attention to in laser cutting machine lens maintenance?
1. The material of the focusing lens is zinc arsenide (ZnSe), which is sensitive and fragile, so be careful and gentle when loading and unloading, and avoid contact with sharp and hard objects.
2. The surface of the focusing lens is covered with an anti-reflection film, which is fragile in nature and is easily affected by oil, pollution, moisture, etc. Therefore, a dry and clean environment should be provided when disassembling the lens. Do not directly touch the lens, because the skin may secrete oil and grease Easy to damage the lens surface.
3. When handling extremely small lenses, it is advisable to use optical tweezers or vacuum tweezers to hold them. No matter what method is used to hold them, they should be held on non-optical surfaces, such as the frosted edge of the edge of the mirror plaque.
4. The choice of wiping paper and solvent should pay attention to matching to prevent secondary pollution and irreversible damage during the wiping process.
5. If the lens is not effective after repeated cleaning, it is recommended to replace the lens in order to ensure the efficiency of the cutting machine.
