What is a Plasma cutting machine?

Since the metal is melted by high-temperature (about 20,000 ° C) arc plasma and the part is blown off by high-pressure air, many of the energized metals (aluminum, brass, iron) can be cut, including stainless steel that cannot be cut by a gas cutting machine. Is possible. Cut by sandwiching the ground between the mother body you want to cut. Compared to gas cutting machines, plasma cutting machines do not require gas cylinders such as acetylene and oxygen, there is no danger of explosion, running costs are low, workers do not need qualifications (gas welding skill training), and cutting. Since the heat input to the surface is small, the advantage is that there is little distortion, but it is necessary to prepare a power supply and an air compressor. Laser cutting is suitable for precision cutting because the width of the cutting groove is narrow, but it is not good at cutting thick ones, and the installation cost is high.

Application of Plasma cutting machine

Used in the field of steel structure manufacturing, construction machinery vehicles (trucks, forks, agricultural machinery), building structures (bridges, tunnel shields, building construction), plant structures (Gulf cranes, thermal power plants), ships , Used in railroad cranes, etc., and is mainly used for large cutting members, but it is also used in the dismantling of automobiles.
