CO2 Laser Cutting (Industrial Application and Key ...

CO 2 laser cutting uses a focus lens to gather CO2 laser beams on the material surface for melting them. At the same time, the coaxial compressed gas blows away the materials melt, making laser beams and materials do relative motions along a certain path and forming a certain shape of cutting seam. Since the 1970s, as the CO2 laser and the ...
