There are many kinds of consumable parts for laser cutting machine. Today, I mainly introduce 19 20 25 27 30 38.1 50.8 laser reflective mirror in laser cutting machine. As the name suggests, protective lens used to prevent dust and slag from damaging the focusing lens. In addition to being used in laser cutting machine, it is also necessary in the other laser equipment, including laser marking, laser welding and laser engraving. It can be seen that the application market for protective lenses is very large.
The price of 19 20 25 27 30 38.1 50.8 laser reflective mirror on the market is not equal. The price difference from tens of yuan to several hundred yuan is very different, and the quality is also different. Of course, it is not uncommon to recharge. If the lens is not properly selected, it will cause large laser loss, frequent damage to the protective lens, and unstable product quality, causing serious losses to the enterprise. Therefore, choosing the right protective lens is a very important thing to pay attention to.
The 19 20 25 27 30 38.1 50.8 laser reflective mirror of the laser cutting machine is selected in three steps:1) The size is matched, this is easy to understand;2) Material, according to different laser power, consider the cost of use, you can choose K9, quartz, in the actual application process, professional manufacturers divide the two types of materials into multiple grades, customers can choose the corresponding specifications according to actual needs.3) Coating, laser anti-reflection film, using different coating technical parameters according to the use environment.
Although the protective lens of the laser cutting machine is a wearing part, in order to improve its utilization rate and reduce the production cost, the lens can be cleaned by timing to achieve the purpose of recycling. The following are three cleaning steps summarized by the high-energy laser:
1. The protective lens material is Zn Se (zinc arsenic), which is relatively brittle and afraid of falling; it should be noted during disassembly and assembly: it should not be too hard and cannot collide with hard objects. There are anti-reflection coatings on the surface, which are afraid of pollution, fear of moisture, oiliness, and fear of scratching. Therefore, it is required to provide dry and degreasing air in the work. Do not directly handle the lens of the laser cutting machine to protect the lens because of the skin oil. It will cause permanent damage to 19 20 25 27 30 38.1 50.8 laser reflective mirror surface. Conversely, you can work with gloves and their special sets. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to protect the lens from the laser cutter, it can only be clamped along a non-optical surface, such as the frosted edge of the mirror edge.2. Under normal circumstances, it is necessary to check the19 20 25 27 30 38.1 50.8 laser reflective mirror of the laser cutting machine before and before and after cleaning. Because most contaminants and surface defects are relatively small in size, we often need to use amplification equipment when inspecting19 20 25 27 30 38.1 50.8 laser reflective mirror. In addition to amplifying equipment, sometimes we need to use a relatively bright light to illuminate the optical surface, enhancing the specular reflection intensity of surface contaminants and defects, which makes it easier to spot contaminants and defects.3. When cleaning a laser cutting machine laser reflective lens, always use a clean wipe and optical grade solvent to prevent damage from other contaminants. Wipe paper must be wetted with a suitable solvent and must not be used dry. In consideration of softness, the usable wiping paper is a cotton Web wiping paper or an applicator such as a cotton ball, a lens paper, and a cotton swab.
