CNC plasma cutting is a type of thermal cutting in which electricity is transferred from the machine to the workpiece (material) using plasma gas, this will cause the material to heat up and melt, then The ionized steam hits the work piece at a high speed and disperses the molten material and cuts the work piece.
What is a plasma?
In simple words, if we heat the solid material enough, a liquid will be obtained, if we heat the liquid enough, it will become a gas, and if we heat the gas enough, plasma will be formed, which has very high thermal properties and is used in the cutting industry. (light and heavy metal structures, construction, shipbuilding, cars, etc.) it is used. CNC plasma is one of the most widely used methods in the cutting industry, which is very accurate and faster than the methods works traditionally, also provided that the device is properly set and programmed, the cutting operation in the CNC plasma machine does not leave any scraps or chips. (designs and patterns on flat sheets) is used.
What gas is used in the plasma and air cutting machine?
For cutting, you need neutral or nitrogen gas, which can be supplied from air compressors, air cylinders, or nitrogen gas. inches and high-flow systems use nitrogen gas; Because nitrogen creates a higher quality cut in most materials, including stainless and mild steel, stainless steel, aluminum, but for metals with higher thickness, it is better to use nitrogen gas and air.
