How does the CO2 laser engraving machine work?

The CO2 laser engraving machine uses the gas laser with the infrared light band. CO2 gas is charged into the high-voltage discharge tube to generate glow discharge, so that the gas molecules release laser. And after the amplification, the laser energy forms a laser beam for material processing. The laser beam irradiates on the materials on the working table through the transmission of the lens.

And under the strong thermal energy of the laser, the temperature of the materials increases sharply. The working point melts or vaporizes rapidly due to high temperature. With the moving route of the laser head, the machine completes the processing and achieves the effect of engraving.

The CO2 laser engraving machine connects with the computer through the data cable, and the supporting software is installed in the computer. The users can input the designs or graphic patterns into the control system of CO2 laser engraving machine through software.

CO2 laser processing technology belongs to non-contact processing. It will not directly contact with the materials during processing. Therefore, this laser machine will not change the inner structure of the materials. It relies on the high density of laser energy and has strong laser engraving operation performance.

In comparison with the traditional mechanical engraving technology, the CO2 laser engraving machine has a quicker working speed and higher efficiency. It can engrave more complicated computer graphics, and can cut vertical letters with more accuracy. The acrylic letters or boards after processing have no need for further polishing treatment. CO2 laser engraving machine can also engrave or cut glass, leather and rubber foam boards. Generally, the users need not to fix the materials for engraving especially.
