Imported main board and chip are adopted, and the engraving control is more precise. Using imported bearings and high-precision spring belts, not only the engraving is more precise, but the machine life is 2-3 times that of ordinary CO2 engraving machines. Reinforced and thickened fuselage, absolutely safe transportation and longer service life. Built-in cooling fan to reduce the temperature of all electronic components. Thus, increased service life of electronic components and higher technical volatility. High-precision stepping motor, more precise engraving.
