20W fiber laser marking machines can actually be divided into many types. We can divide them into desktop type, all-in-one type, portable type, hand-held type according to the appearance, and then they can be divided into fiber laser marking machine and co2 laser marking machine according to the type of laser installation. Labeling machine, UV laser marking machine, etc., let’s introduce the 20W laser marking machine below. 20W fiber laser marking machine: The marking machine of the fiber laser marking machine is a fiber laser, which has the characteristics of small size (no water cooling, air cooling), good beam quality (basic mode), and maintenance-free. It is mainly composed of laser, The galvanometer and playing cards are composed of three parts. The laser produced by the fiber laser marking machine has the beam quality, 1064nm output center, and the service life of the whole machine is about 100,000 hours, which is longer than other types of laser marking and exceeds 28% electro-optic The conversion efficiency, compared with other types of laser marking machines and 2% - 10% conversion efficiency, has a huge advantage in energy saving and environmental protection. Fiber laser marking machine Equipment features: suitable for processing various metal and non-metal materials. In particular, it is more advantageous to mark high-hardness, high-melting-point brittle materials. Belongs to non-contact processing, no damage to the product, tool wear, good quality sign. The laser beam is thin, the material consumption is small, the heat-affected zone is small, and the processing efficiency is high. , using computer control, easy to automate. Products are widely used in integrated circuit chips, computer accessories, industrial bearings, clocks, electronics and communication products, aerospace equipment, various auto parts, household appliances, hardware tools, molds, wires and cables, food packaging, jewelry, graphics and text Marking and protecting tobacco and many other fields, as well as large-scale production lines.
