As a modern precision processing method, laser marking machine has incomparable advantages compared with traditional processing methods such as printing, mechanical scribing, and EDM. Laser marking equipment has the characteristics of maintenance-free, adjustment-free, and high reliability, and is especially suitable for fields that require high precision, depth, and smoothness. Therefore, it is widely used in the luxury goods industry, and the metal products that can be processed include iron, copper, stainless steel, gold, alloys, aluminum, silver and all metal oxides. Laser marking machines are always guided by the needs of users, relying on strong technical force, and based on the research and development principles of providing users with the most advanced and most suitable products, tailor-made the best products for users. From an industrial point of view, fiber laser marking machines are widely used in integrated circuit chips, computer accessories, industrial bearings, clocks and watches, electronic communication products, aerospace devices, various auto parts, household appliances, hardware tools, molds, wires and cables Graphics and text marking in many fields such as food packaging, jewelry, tobacco, military, and mass production lines. Main advantages: 1. Low manufacturing cost, mature technology, and the advantages of miniaturization and intensification brought about by the flexibility of glass fiber; 2. Glass fiber does not need as strict phase matching as crystal for incident pump light, because the glass matrix The uneven broadening caused by Tucker splitting leads to a wider absorption band; 3. The volume-to-area ratio of the glass material is extremely low, the heat dissipation is fast, and the loss is low, so the up-conversion efficiency is high and the laser threshold is low; the output of the fiber makes the laser easily capable of various The processing application of multi-dimensional arbitrary space, and makes the design of the mechanical system very simple. It can adapt to harsh working environments and has high tolerance to dust, vibration, shock, humidity and temperature. There is no need for thermoelectric refrigeration and water cooling, only simple air cooling is required. 4. High electro-optic efficiency: The comprehensive electro-optic efficiency is as high as 20%, which greatly saves power consumption and operating costs.
