There are many kinds of consumable parts for laser cutting machines. Today, I mainly introduce the 12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical lens in laser cutting machines. As the name suggests, 12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical lens are used to prevent dust and slag from damaging the focusing lens. In addition to being used in laser cutting machines, it is also necessary in other laser equipment, including laser marking, laser welding and laser engraving. . It can be seen that the application market for 12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical lens is very large.The price of protective lens on the market is not equal. The price difference from tens of yuan to several hundred yuan is very big, and the quality is also different. Of course, it is not uncommon for shoddy. 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 right12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical lens is a very important thing to pay attention to.

Talking about the laser cutting machine lens selection steps

Choose the12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical lens of the laser cutting machine 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 12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical 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. The12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical 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. Permanent damage to the lens surface. Conversely, you can work with gloves and their special sets. For smaller lens, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to protect the12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical 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 the laser cutting machine12mm 18mm 19mm 19.05mm 20mm 22mm 25mm 28mm 38 .1mm Co2 laser optical lens before and after cleaning. Because most contaminants and surface defects are relatively small in size, we often need to use amplification equipment when inspecting lenses. 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 cutter to protect the 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 wiping paper or an applicator such as a cotton ball, a lens paper, and a cotton swab.
