The basic principle of CNC plasma cutting machine

One of the necessary equipments for mechanical equipment processing is the CNC plasma cutting machine. It is the motion control of precision machinery through computer and servo system, so as to achieve the purpose of fast and accurate cutting of arbitrary graphics. CNC plasma cutting machine is a numerical control technology. , computer software, hardware technology, plasma cutting technology, precision machinery technology in one of the high-tech.

Welding and cutting are extremely important in industrial manufacturing. CNC plasma cutting replaces the complicated and backward manual and mechanical operations due to its high efficiency and accurate size. Moreover, because of its relatively small investment, the maintenance is relatively simple, and the running cost is extremely low. It is widely used in aviation, aerospace, engineering machinery, general machinery, pressure vessels, sheet metal casings, steel structures, shipbuilding, advertising texts, wrought iron products, handicrafts, etc.

Basic principle of plasma cutting

The human known substances have four states, namely, solid state, liquid state, gas state, and plasma state. When the gas reaches a very high temperature, it enters the plasma state. Energy begins to completely separate the molecules, and the atoms begin to split. The usual atoms are composed of nuclei, neutrons and neutrons, and electrons surrounding the nucleus. In the plasma state, electrons are split from the atoms. Once heat disengages the electrons from the atom, the electrons begin to move at high speed. The electrons are negatively charged and the remaining nuclei are positively charged. These positively charged nuclei are called ions. When a gas that is moving at a high speed when the gas is ionized hits other electrons or ions, it will release a huge amount of energy. It is these energies that give the plasma state a special property.

When the bundled plasma is used for cutting, the metal is locally rapidly melted (partially vaporized) and at the same time the molten metal is blown away by the high-speed airflow to form a narrow slit, which not only has a fast cutting speed but also has a narrow slit, the slit Flat, the heat effect is small, and the workpiece deformation is small. Solved the problem that many materials cannot be cut by flame.
