What Is the Principle of Carbon Dioxide Cutting Machine?

2025-08-26

CO2 laser cutting machine, also known as CO2 laser cutting machine. This kind of laser cutting machine currently has huge advantages in cutting non-metallic materials and is widely used. Let's take a look at the principle and configuration of CO2 laser cutting machine and the scope of application!

 

The Carbon dioxide cutting machine is called CO2 laser cutting machine is because it is a laser cutting machine that uses a carbon dioxide laser. This laser belongs to a gas molecular laser. The working substance of it is carbon dioxide gas, and the auxiliary gases are nitrogen, xenon, etc. The laser wavelength is 10.6 microns. It has good stability and an energy conversion efficiency of 25%, which can be used as a laser with high power output.Laser generation principle: The discharge tube of the CO2 laser is filled with mixed gases such as CO2, N2, and He. The ratio and total air pressure of our CO2 laser cutting machine can vary within a certain range (generally: CO2:N2:He=1:0.5:2.5 The total air pressure is 1066.58pa), but generally after you buy the laser tube, the ratio is fixed. Any molecule has three different forms of movement. One is the movement of electrons in the molecule, which determines the electron energy state, and the other is the vibration of atoms in the molecule. The atoms are constantly vibrating around their equilibrium position. This kind of movement determines the vibration energy state of the molecule, and the third is the rotation of the molecule, which determines the rotation energy state of the molecule. If you don't understand this part, you can go to Baidu for related knowledge. CO2 lasers use the vibration of CO2 molecules and the transition between rotational energy levels to produce lasers.

The CO2 laser cutting machine we are talking about here refers to the CO2 glass tube laser. In fact, the CO2 laser also has a kind of radio frequency tube, which is generally used in laser marking machines. The glass tube is also useful in marking machines, but compared to the radio frequency tube marking machine, in terms of laser marking, the laser of the glass tube is not stable enough under long-term continuous operation, and the service life is short, and the marking efficiency is not as good as that of the radio frequency tube.However, in terms of cutting, glass tube lasers are basically used. Because the depth requirements for cutting are generally relatively high, glass tube lasers that are suitable for large-power and low-cost are more economical and affordable. The CO2 laser cutting machine adopts water cooling for cooling, and the cooling water circulates in the glass tube. In the working state, the glass tube laser will produce high pressure, so never touch the laser while the laser cutting machine is running.

 

In terms of application, CO2 laser cutting machine is mainly used for cutting non-metallic materials, such as fabrics, the jeans we wear, some holes or old colors are processed by this CO2 laser cutting machine. In addition, leather, plastic, acrylic, etc. Can also use CO2 laser cutting machine. If the power is relatively large, the CO2 laser cutting machine can also cut metal, but the accuracy is generally not too high, and it can't cut too thick. Compared with the fiber laser cutting machine, it is still relatively insufficient, so it is used less in cutting metal.
