The working principle of the CO2 laser cutting machine is to use a carbon dioxide gas laser to generate a high-energy-density laser beam, focus it and
irradiate it on the surface of the material to be cut, causing the material to quickly melt, vaporize or reach the ignition point. At the same time, the melted or burned
material is burned with the help of high-pressure gas. Material is blown away, resulting in high-precision cutting. 12
The main components of a CO2 Laser cutting machine include the laser, the output lens set, the optical system and the welding head. The laser is the
core of the carbon dioxide laser cutting machine and is responsible for converting electrical energy into laser energy. The output lens group and optical path system
work together to focus the laser beam onto the workpiece to ensure efficient use of laser energy. The welding head is the part where the laser beam comes into
contact with the workpiece, including an automatic tracking system and a protection system to keep the distance between the laser beam and the workpiece constant
and prevent workers from touching the laser beam and causing danger.
The process of laser cutting involves focusing a laser beam onto the surface of the workpiece, exceeding the vaporization temperature of the workpiece material, and
partially heating it to vaporize it. As the material inside the workpiece is vaporized to form a gas, the gas reduces the absorption of light so the beam can continue
downward through and heat the next layer of material, creating the cut. The depth of cutting depends on factors such as laser power, focal length, beam diameter,
cutting speed and workpiece material.
CO2 laser cutting machines have a wide range of applications, including cutting of metal and non-metal materials. They have the characteristics of high
precision, fast cutting, not limited to cutting pattern restrictions, automatic typesetting to save materials, smooth incisions and low processing costs. These advantages
allow carbon dioxide laser cutting machines to gradually replace traditional cutting process equipment in industrial production.
