Plasma cutting machine principle and application
Plasma cutting machine manufacturers plasma cutting machine is a new type of thermal cutting equipment. Its working principle is based on compressed air as the working gas, high temperature and high speed plasma arc as the heat source, localized melting of the metal to be cut, and simultaneous high-speed airflow The molten metal is blown away to form a narrow slit. Plasma cutting machine can be used for cutting stainless steel, aluminum, copper, cast iron, carbon steel and other metal materials, not only cutting speed, narrow slits, flat cuts, heat affected zone is small, the workpiece deformation is low, the operation is simple, and has a significant The energy-saving effect. Plasma cutting machine is suitable for the manufacture, installation and maintenance of all kinds of machinery and metal structures. It is used for cutting, opening, digging and beveling of medium and thin plates.
Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and vaporize) the metal at the notch of the workpiece and remove the molten metal by the momentum of the high-speed plasma to form the notch.
Up to now, the working gas can be used (working gas is the plasma arc of the conductive medium, but also carrying heat, but also to exclude the molten metal in the incision) on the plasma arc cutting characteristics and cutting quality and speed are obvious influences. The plasma arc working gas commonly used in plasma cutting machines includes argon, hydrogen, nitrogen, oxygen, air, water vapor, and some mixed gases.
