CNC plasma cutting machines are similar to laser cutters, but instead of a laser beam, CNC plasma cutting involves a plasma torch.
Plasma is a gas that has been heated to the point where its atoms lose their electrons. Plasma cutters use a nozzle to contain pressurized gas (oxygen, nitrogen, or natural air) and an electrode. The electrode is charged with a power supply, which ionizes the gas in contact with it. The plasma arc then travels through the nozzle towards the conductive material and cuts it.
Plasma cutters are excellent for cutting tough metals like steel, and they can cut both thick and thin metal sheets. But, they are only 2D cutting machines, and cannot cut any 3D shapes, like standard laser cutters, and 3-axis CNCs
