Advantages of fiber laser marking machine in use

Apr 27,2023 | TOPTEK

Fiber laser marking machines use a laser beam to create permanent marks on the surface of various materials. The function of marking is to expose the deep material through the evaporation of the surface material, or to "carve" traces through the physical changes of the surface material through light energy, or to burn part of the material through light energy, and to display the required etching patterns, characters, barcodes and others. graphics.

Main advantages:
1. The advantages of miniaturization and intensification brought about by the low manufacturing cost of glass optical fiber, mature technology and repeatability of optical fiber;
2. Unlike crystals, glass fibers do not require strict phase matching of the incident pump light, which is due to the wide absorption band caused by the uneven broadening caused by Stark splitting of the glass matrix;
3. The glass material has an extremely low volume-to-area ratio, fast heat dissipation, and low loss, so the up-conversion efficiency is high and the laser threshold is low;

4. The output laser has many wavelengths: this is because the energy levels of rare earth ions are very rich, and there are many types of rare earth ions;
5. Tunability: Due to the wide energy level of rare earth ions, the fluorescence spectrum of glass optical fiber is wide;
6. Since there is no optical lens in the resonant cavity of the fiber laser, it has the advantages of no adjustment, no maintenance, and high stability, which is unmatched by traditional lasers;
7. The optical fiber output enables the laser to be conveniently used in various multi-dimensional arbitrary space processing applications, making the design of the mechanical system very simple;

8. It can adapt to harsh working environment and has high tolerance to dust, vibration, shock, humidity and temperature; 
9. No need for thermoelectric refrigeration and water cooling, only simple air cooling;
10. High electro-optic efficiency: The comprehensive electro-optic efficiency is as high as 20%, which greatly saves the power consumption during work and saves operating costs. Commercially available high power fiber lasers are 6 kW.
11. Using laser as the processing method, there is no processing force between the workpieces, which has the advantages of no contact, no cutting force, and small thermal influence, ensuring the original precision of the workpiece. At the same time, it has wide adaptability to materials, can make very fine marks on the surface of various materials, and has very good durability;
12. The space control and time control of the laser are very good, and the degree of freedom for the material, shape, size and processing environment of the processing object is very large, especially suitable for automatic processing and special surface processing. And the processing method is flexible, which can not only meet the needs of laboratory single-item design, but also meet the requirements of industrial mass production;
13. Laser engraving is fine, and the lines can reach the order of millimeters to microns. The marks made by laser marking technology are difficult to be copied and changed, which is extremely important for product anti-counterfeiting;
14. The combination of laser processing system and computer numerical control technology can form high-efficiency automatic processing equipment, which can print various characters, symbols and patterns, and is easy to use software to design marking patterns, change marking content, and adapt to modern production efficiency and fast-paced requirements;

15. Laser processing has no pollution source, which is a clean and pollution-free high environmental protection processing technology.
