Double Work Platform Can install double work platform, both blade work table and honeycomb work table, can use to do both cutting and engraving. High Efficiency Particle Air Filter Environmental protection without pollution Three-stage filtration The first is bag filtration of large particles. The second IS HEPA filtration of particles larger than that of 0.03um. The third is activated carbon adsorbs of smoke and dust odour. Yongli Laser Tube Using Yongli laser tube, its photoelectric conversion efficiency is high, the laser output power density is high, the beam is concentrated, and the spot is uniform. The engraving/cutting speed is fast and the engraving line is deep and narrow with high resolution and clear characters. The work life of laser tube is long and the fault rate is low.
