CO2 laser marking machine, namely carbon dioxide laser marking machine, is a laser galvanometer marking machine that uses CO2 gas as the working medium. Using CO2 radio frequency laser, the laser wavelength is 10.64um, and the life span is as long as 20,000 to 40,000 hours. The marking speed is fast and the lines are fine. Due to its good performance, it can be matched with the production line. General purpose model, rear focus mode, small size and high degree of integration.
