Focusing lens of laser cutting machine is a kind of more precise optical components, laser cutting machine protection lens is very important to laser cutting machine, its clean degree directly affects the processing performance and quality of laser cutting machine.If the lens is not selected properly, it will cause large laser loss, frequent damage to the protective lens and unstable product quality, which will cause serious losses to enterprises.Although the protective lens of the laser cutting machine belongs to the vulnerable parts, in order to improve its utilization rate and reduce the production cost, the protective lens can be cleaned regularly to achieve the purpose of reuse.Therefore, the laser cutting machine protection lens should be regularly maintained:
1. The focusing lens material is ZnSe(arsenic zinc), which is relatively brittle and afraid of falling;Attention should be paid to the disassembly and assembly: not too hard, and can not collide with hard objects.The surface has antireflective film, afraid of pollution, afraid of wet, afraid of oil, afraid of scraping;Therefore, it is required to provide dry and oil-free air at work. Do not directly handle the lens of the focusing lens of the laser cutting machine by hand, because the skin grease will cause permanent damage to the surface of the lens.Instead, you can wear gloves and a special sleeve for the operation. For smaller lenses, optical tweezers or vacuum tweezers are more convenient.No matter what method is used to clamp the laser cutting machine focus lens, it should only be held along a non-optical surface, such as the frosted edge of the plaque.
2. In general, it is necessary to check the focusing mirror of the laser cutting machine before and after use and cleaning.Because the size of most contaminants and surface defects is relatively small, we often need to use magnifying equipment when examining lenses.In addition to amplifying equipment, sometimes we need to shine a brighter light on an optical surface to enhance the specular reflection of contaminants and defects on the surface, so that contaminants and defects can be found more easily.
3. When cleaning the focus mirror of a laser cutting machine, always use clean wipe paper and optical-grade solvents to prevent damage by other contaminants.Wipe paper must be moistened with appropriate solvent, must not be used dry.For the consideration of softness, the available wipe paper is pure cotton wipe paper or applicators such as cotton ball, lens paper, and cotton swab.
The focusing lens of laser cutting machine is a consumable product. When it is cleaned many times, it is necessary to pay attention to replacement to ensure the processing efficiency of laser cutting machine, so as not to delay production.
