Application of laser cutting technology in machinery manufacturing
Main types of laser cutting technology Vaporization cutting Vaporization cutting is the most widely used cutting form in laser cutting technology. The laser power density used in this cutting technology is high. Once the laser is irradiated on the mechanical workpiece, except for a few Part of it will be reflected, and most of it will be successfully absorbed and converted into heat energy, causing the surface of the workpiece to reach the boiling temperature in a short time and forming a keychain on its surface. In addition, due to surface oxidation and other effects, the absorption rate will be greatly increased, and the ejected steam will effectively take away […]
