Working principle of Air plasma cutting machine
Air plasma cutting machine is a new type of thermal cutting equipment. His working principle is to use compressed air as working gas. Using a high-temperature and high-speed plasma arc as a heat source, the cut metal is partially melted, and at the same time, the molten metal is blown away with a high-speed air flow to form a narrow slit. The equipment can be used for cutting various metal materials such as stainless steel, aluminum, copper, cast iron, carbon steel and so on. Not only the cutting speed is fast, the slit is narrow, the incision is flat, and the heat affected area is small. The workpiece has a low degree of deformation, simple operation, and has a significant energy saving effect. This equipment is suitable for the cutting, opening, digging and slope cutting of thin plates in the manufacture, installation and maintenance of various machinery and metal structures. For example, Zoomlion adopts this kind of technology in the processing of thin plate parts of large quantities of products such as engineering cranes, pump trucks, mixer trucks, etc., and has achieved significant economic benefits.
