Small size, low power consumption, the power consumption of the whole machine is less than 500W, water cooling method, small footprint, easy installation, truly energy-saving and portable. High electro-optical conversion efficiency, easy to use, no need for optical adjustment or maintenance, compact structure, high system integration, and fewer failures. Does not require any maintenance, has a long service life and is suitable for working in harsh environments. The processing speed is fast, which is 2-3 times that of the traditional marking machine. The optical scanning galvanometer, the laser repetition frequency is high, and the high speed has no distortion.
