Professional pipe cutting software is one of the core technologies of CNC pipe cutting machine to realize "full time cutting and high efficiency cutting", which is the fundamental guarantee to effectively save material and improve cutting efficiency. The unique floating escrow device, while the pipe is feeding and rotating, the escrow device always keeps contact with the pipe surface, the support force is set according to the pipe specification, ensuring effective support, preventing the pipe from sagging, reducing the axis swing when the pipe is rotating, and improving the processing accuracy. Automatic bundle loading function can reduce the number of operators and improve the processing efficiency. Automatic identification system of pipe section, can mix and load many kinds of pipes, automatically prompt the type of pipe, automatically retrieve the process library, and prompt the optional processing program. ♦SMC high precision servo proportional valve, precisely control the air pressure of cutting auxiliary gas and the size of chuck clamping force to achieve the best cutting effect. ♦The pipe linear positioning speed reaches 100m/min and the rotary positioning speed can reach 120m/min.
