Using fiber optic output laser, and then by high-speed scanning oscillator system to achieve marking function, to achieve high accuracy of fiber laser marking position, marking surface is not deformed. The whole machine is compact, easy to move, good output beam quality, high reliability, suitable for any office occasion that requires mobile marking. No optical pollution, small power coupling loss, high efficiency of electro-optical conversion, cooled by air-cooled mode. Fiber laser marking machine adopts integrated structure dissection, computer control, easy to realize automation, can diy marking by itself, high processing efficiency.
