Laser Cutting Machine Industry Information
The laser cutting machine focuses the laser light emitted from the laser device into a high power density laser beam through the optical path system. The laser beam is irradiated on the surface of the product to make the product reach the melting or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.
As the relative position of the beam and the product moves, the material will eventually form a slit, so as to achieve the purpose of cutting
Laser cutting machine laser source information
Co2 laser source
CO2 laser light source requires a lot of energy to excite nitrogen molecules to collide with CO2 molecules, causing them to emit photons and eventually form a laser beam that can cut through metal
Fiber laser source
Fiber lasers use solid-state diodes to pump molecules in the double-clad ytterbium-doped fiber, and the stimulated emission of light passes through the fiber core multiple times, and then the laser is output through the transmission fiber to the focusing head for cutting
Laser cutting machine main process
Vaporization laser cutting
In laser vapor cutting, optimal beam focusing depends on material thickness and beam quality.
Laser power and heat of vaporization have only a certain influence on the optimal focus position.
Melt laser cutting
Laser melting cutting, the workpiece is partially melted and then the molten material is ejected by airflow
Oxidation melting laser cutting
Fusion laser cutting is generally uses inert gas. If it is replaced by oxygen or other active gas, the material is ignited under the irradiation of the laser beam, and a violent chemical reaction occurs with oxygen to generate another heat source, which further heats the material.
Controlled Fracture Laser Cutting
Fracture laser cutting is a high-speed, controllable cutting of brittle materials that are easily damaged by heat through laser beam heating
