Pipe cutting machines are mainly used for cutting metal pipes. Pipe cutting machines are divided into several categories: CNC laser cutting machines, pipe cutting machines, water plasma cutting machines, CNC flame cutting machines, etc. Among them, pipe cutting machines and CNC flame cutting machines are the two most commonly used cutting machines in the metal manufacturing industry; pipe cutting machines, as rough processing equipment, are mainly used for material cutting. The working place and working environment of the pipe cutting machine are relatively harsh and the metal dust is relatively large. Therefore, it is necessary to carefully clean and maintain the machine, and a dedicated person should be responsible for the lubrication, repair and maintenance of the equipment! In the mechanical processing process, our commonly used plate cutting methods are manual cutting, semi-automatic cutting machine cutting and pipe cutting machine cutting. Compared with the other two cutting methods, CNC cutting can effectively improve the efficiency and cutting quality of plate cutting and reduce the labor intensity of the operator.
