Fiber laser marking machine uses fiber laser to output laser, and then realizes marking function through super high speed scanning galvanometer system. Fiber laser marking machine has high optical conversion efficiency, uses air cooling mode to cool, small size, good output beam quality, high reliability, super long operation life, energy saving, high efficiency, long life and maintenance-free, which traditional laser does not have. Yes. This kind of laser can engrave metal materials and some non-metallic materials. It is mainly used in areas requiring high depth, smoothness and fineness, such as stainless steel ornaments, clocks and watches, moulds, IC and keys of mobile phones. Bitmap marking can engrave exquisite pictures on metal and plastic surfaces. The marking speed is the first generation of traditional lamp pump marking machine and the second generation. It is 3 to 12 times of the semiconductor marking machine.
