Abstract: Thanks to rapid development of pipeline automatic welding technology, the requirements on pipe-end facing is higher and higher for welding technique. The groove form and precision are the key factors to influence welding quality. Pipe-end facing machines of PFM series have such advantages as precise positioning and coring, high cutting force, quick in cutting speed and high precision. The series can process various grooves, such as V type, U type, X type and composite types. The tracing profile mechanism on the rotating cutterhead can keep the processed bevel shape in line with the requirements. The throttle automatic control system can allow the processing speed and idle to interchange. With operational convenience and other advantages, this series fully satisfies the engineering demand and has become the indispensible key equipment for pipeline welding. Localization of pipe-end facing machine of the PFM series has broken foreign technological blockage and price monopoly, satisfied the demand for bevel form and precision in the pipe-end automatic welding technological sector, and effectively improved the technological level and economic results of China's pipeline construction.
