What is the marking principle of fiber laser marking machine

    The so-called fiber laser marking machine means that this marking machine uses a fiber laser generator. The fiber laser generator has the characteristics of small size (no water cooling device, using air cooling), good beam quality (basic mode), and maintenance-free. Now the fiber laser equipment can not only reduce the maintenance cost, but also greatly extend the service life, the marking effect is more fine and clear than the original. The application field of fiber laser marking machine is very wide,it can be applied to integrated circuit chips, computer accessories, industrial bearings, watches, electronics and communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, Marking of graphics and text in many fields such as food packaging, jewelry, tobacco and military affairs, etc.

   Fiber laser equipment uses a high energy density laser beam to act on the surface of the processed product. Under the action of high energy, the marked surface quickly vaporizes or chemical reactions occur, thereby leaving traces on the product surface. The processed surface is not only smooth and natural, but also does not damage the material near the marked surface. Laser processing is different from traditional processing methods. Laser processing requires that the surface of the processed material itself can absorb the laser beam of this wavelength before it can be processed, but traditional processing does not have this requirement. However, laser processing does not require consumables and will not cause deformation of the product. The computer is used to control and operate flexibly during processing.

     It is these excellent performances that make the application range of fiber laser equipment increasingly widespread, and have begun to replace traditional processing methods in many fields. Continuously improving and upgrading technologies are constantly striking the market occupied by traditional industries. In terms of price, the price of fiber laser marking machine is much more expensive than traditional equipment, but the excellent performance and lower maintenance cost have won the favor of many industries. Especially for marking materials with high hardness, high melting point and brittleness, it is more advantageous.
