To maintain the focusing lens of laser cutting machine, the following three points should be noted

1. The focusing lens material is ZnSe (arsenic-zinc zinc), which is relatively brittle and is afraid of falling; Be careful when disassembling: do not force too hard, and do not collide with hard objects. There is a film on the surface, which is afraid of pollution, moisture, oil and scratch. So the requirement in the work to provide the air drying, degreasing, don't directly deal with laser cutting machine with the hand focusing mirror lens, because the skin grease can produce permanent damage to the lens surface. Instead, you can wear gloves and special kits to operate, making it easier to use optical or vacuum tweezers for smaller lenses. No matter what method is used to clip the focusing mirror of the laser cutting machine, it can only be clamped along non-optical surface, such as the frosted edge of the plaque.
2. In general, it is necessary to check the focusing mirror of laser cutting machine before use and before and after cleaning. Because most of the contaminants and surface defects are small in size, we often need a magnifying device when checking the lens. In addition to amplifying device, sometimes we need to use a more bright beam of light to illuminate optical surface, enhance the strength of specular reflection surface contaminants and defects, so that we can more easily find contaminants and defects.
3. When cleaning the focusing mirror of a laser cutting machine, clean wiping paper and optical solvents are often used to prevent damage by other pollutants. Wipe paper must be moistened with appropriate solvent, must not be used dry. In consideration of softness, available wipe paper is pure cotton Webril wipe paper or cotton ball, lens paper, and cotton swab applicators.
Laser cutting machine of the focus lens this belongs to consumable, when clean after many times still short of change must be noticed when high cleanliness, guarantee the efficiency of laser cutting machine, so as not to delay the production.
