Carbon dioxide laser cutting machine: in-depth analysis of working principle and industry application

In the wave of modern manufacturing industry, laser cutting technology has become the preferred processing method for many industries with its high precision, high efficiency and non-contact processing characteristics. Among them, carbon dioxide (CO2) laser cutting machine has occupied a pivotal position with its unique working principle and wide application field. This article will deeply explore the working principle of CO2 laser cutting machine and its in-depth application in various industries.

Working principle of CO2 laser cutting machine

CO2 laser cutting machine is a laser cutting equipment with CO2 gas as the working medium. Its working principle is based on molecular vibration theory. CO2 molecules are linear symmetrical molecules. The two oxygen atoms are on both sides of the carbon atom. The gas discharge excites the molecular vibration and rotational energy level transition, thereby generating an infrared laser with a wavelength of 10.6 microns. After this laser beam is focused by a focusing mirror, it can form a high-energy spot, use the thermal effect to melt and vaporize the material, and use the compressed gas coaxial with the laser beam to blow away the melted material to form a certain shape of the slit.
