Cost-effective laser beam quality is excellent, photoelectric conversion rate is high, stable power, reliable performance, no consumables, maintenance free, long service life. High speed scanning galvanometer adopts domestic and foreign famous brands, fast speed, high precision, can be continuously applied in a variety of harsh environment. The high quality field mirror system has high resolution, good light sense, small loss, more uniform beam distribution, and improves the marking accuracy. Scanning before red light positioning marking, preview marking position in advance, identify positioning size, so that each workpiece marking position accurate without error. The lifting shaft and ruler are specially humanized design, strong and durable, clear scale, improve the accuracy of adjustment, more accurate calibration. Flexible positioning of porous position, beautiful atmosphere, with the machine equipped with positioning bar assist positioning.
