Overview Of Fiber Laser Marking Machine

Fiber laser marking machine is a laser that uses rare-earth element-doped glass fiber as the gain medium. Fiber laser marking machine has become a hot spot in laser physics research in recent years, and it is unanimously considered to be a new generation of products that may completely replace solid-state lasers. Fiber lasers can be developed on the basis of fiber amplifiers: under the action of pump light, it is easy to form high power density in the fiber, resulting in the "number inversion" of the laser energy level of the laser working material. When a positive feedback loop is properly added ( form a resonant cavity) to form a laser oscillation output. Fiber laser marking machines use laser beams to permanently mark the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "engrave" traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the desired etching pattern, text, barcodes and other graphics.

What Are The Advantages Of Laser Marking Technology?

1. The laser is used as the processing method, and there is no processing force between the workpiece and the workpiece. It has the advantages of no contact, no cutting force, and little thermal influence, which ensures the original accuracy of the workpiece. At the same time, it has wide adaptability to materials, and can make very fine marks on the surface of various materials with very good durability;

2. The laser has good spatial controllability and time controllability, and has great freedom in the material, shape, size and processing environment of the processing object, and is especially suitable for automatic processing and special surface processing. And the processing method is flexible, which can not only meet the needs of laboratory-style single-item design, but also meet the requirements of industrial mass production;

3. The laser marking is fine, and the lines can reach the order of millimeters to microns. It is very difficult to imitate and change the marks made by laser marking technology, which is extremely important for product anti-counterfeiting;

4. The combination of laser processing system and computer numerical control technology can form efficient automatic processing equipment, which can print various characters, symbols and patterns, easy to use software to design marking patterns, change marking content, and adapt to the requirements of modern production with high efficiency and fast pace;

5. Laser processing has no pollution sources, and is a clean and pollution-free high-environmental processing technology;

Laser marking technology has been widely used in all walks of life, opening up broad prospects for high-quality, high-efficiency, pollution-free and low-cost modern processing and production.
