What is the main process of laser cutting machine

Laser cutting machine, as a high-precision and high-efficiency cutting equipment, is widely used in industrial manufacturing, construction, automotive and other fields. What is the main process of laser cutting machine?

In the process of laser gasification cutting, the rate at which the surface temperature of the material rises to the boiling point temperature is so fast that it can avoid melting caused by thermal conduction. As a result, some of the material vaporizes into steam and disappears, while others are blown away as ejecta from the bottom of the cutting seam by the auxiliary gas flow. In this case, a very high laser power is required.

In laser melting cutting, the workpiece is locally melted and the melted material is sprayed out by air flow. Because the transfer of materials only occurs in their liquid state, this process is called laser melting cutting.

Melting cutting generally uses inert gases. If oxygen or other active gases are used instead, the material is ignited under the irradiation of a laser beam, and a violent chemical reaction occurs with oxygen to produce another heat source, which further heats the material, known as oxidation melting cutting.
