Fiber laser marking machine principle of fiber laser marking machine is the use of a laser beam at the surface of a variety of materials marked with a permanent marker. Marking effect evaporation surface material is exposed by the deep substance, or by chemical and physical changes in the surface energy leads to material and "carved out" signs, or by light burned some substance, showing etching required patterns, text, bar codes and other graphic-called fiber laser marking machine marking machine which refers to the use of a fiber laser, fiber laser has a small (non-water cooled, use air-cooled), good beam quality (base model) , maintenance-free characteristics mainly by the laser, vibration lens, marking cards of three parts, the use of fiber laser producing laser marking machine, good beam quality, the output of the center of 1064nm, the whole life of around 100,000 hours, compared to Other types of laser marking device longer, electro-optical conversion efficiency of over 28%, compared to other types of laser marking machine 2% to 10% conversion efficiency advantages of large, energy-saving and environmental protection and other aspects of performance Zhuo. Fiber laser marking machine features 1, a variety of metals, non-metallic materials processing, especially for high hardness, high melting point, brittle materials marked even more advantages. 2, a non-contact processing, without damaging the product, no tool wear, good quality mark. 3, the laser beam is small, processing material consumption is very small, small heat-affected zone processing. 4, processing efficiency, the use of computer control, easy to automate. Applications are widely used in many areas of the integrated circuit chip, computer accessories, industrial bearings, watches, electronics and communications products, all kinds of auto parts, home appliances, hardware tools, dies, wire and cable, food packaging, jewelery, tobacco and other graphics and text mark, and mass production line operations.
