Several precautions for arc cutting of CNC plasma cutting machine Plasma arc cutting is a processing method that uses the heat of a high-temperature plasma arc to melt (and evaporate) the metal part or part of the incision of the workpiece, and remove the molten metal by the momentum of high-speed plasma to form an incision. A plasma arc cutting machine is a machine that processes metal materials with the help of plasma cutting technology. 1. Industrial use The CNC plasma cutting machine can cut various metals that are difficult to cut by oxygen-acetylene cutting with different working gases, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel), the cutting effect is better, and its main advantage is that the cutting thickness is different. When cutting large metals, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5 to 6 times that of the oxygen-acetylene cutting method, the cutting surface i...
