Processing technology for galvanized air pipe and cutting machine thereof

The invention relates to the technical field of galvanized air pipe machining, in particular to a machining technology for a galvanized air pipe and a cutting machine for the galvanized air pipe. According to the technical scheme, the method comprises the steps that S1, before the galvanized air pipe cutting process is adopted, the size and shape of a needed air pipe are determined according to the actual situation, and design is conducted; meanwhile, it should be guaranteed that the quality of used materials meets relevant standards, so that the cutting effect and the service life are guaranteed; s2, a high-frequency plasma cutting technology is adopted for conducting preliminary cutting on the whole galvanized air pipe; s3, after high-frequency plasma cutting, an oxidizing agent cutting technology is used for conducting fine machining on the air pipe; s4, after the air pipe is finely machined, the air pipe is cleaned through a liquid metal cutting technology; and S5, finally, an electron beam cutting techno
