What Is The Working Principle Of A Plasma Cutting Machine?

At present, the working principle of the plasma cutting machine is that the local high temperature released by the short circuit of the high-frequency plasma arc and the positive electrode of the product is the "knife edge". The molten metal is blown under the cut surface and forms a slit.

Numerical control plasma cutting technology: It is a technology that combines plasma cutting, plasma cutting machine power supply, and numerical control technology into one to perform precise cutting of metal workpieces.

1. The current ordinary plasma arc cutting machine: For market demand and reducing the cost of use, most of the current products are mainly air plasma cutting machines. At the same time, according to the cutting requirements, special gas can be added for cutting when cutting special metals.

2. Cluster plasma arc cutting: According to the cluster method of plasma arc, it can be divided into water compression plasma arc, magnetic field concentrated plasma arc and so on. Because the plasma arc is compressed and bunched many times, the current density and cutting heat of the plasma arc are concentrated, thereby greatly improving the plasma cutting speed and the quality of the cutting surface.

3. Fine plasma cutting machine: At present, the domestic fine plasma cutting machine technology has matured. With the power supply and the cutting torch combined with the assistance of fine CNC machine tools, the quality of the cutting surface has reached the lower limit of laser cutting. But the cost and cutting thickness are far better than laser cutting.
