There are many structural forms of pipe bending machine. According to the heating method, it can be divided into cnc copper cutting machine and pipe cold forming machine. According to the transmission mode, it can be divided into manual, pneumatic, mechanical transmission and hydraulic transmission. The method can be divided into four types: manual control, semi-automatic, automatic and numerical control. The pipe bending machine is the main equipment for pipe bending processing. The numerical control technology is the core of the pipe bending machine equipment. Our new neutralization machine develops the high-end CNC intelligent numerical control equipment control system to improve the core competitiveness of China's equipment manufacturing industry and improve our country. Comprehensive national strength is of great significance.
