Cold saw is a new on-line cutting technology in the welded pipe industry. The main feature is that it adopts the principle of cold milling. After cutting, the pipe end is flat without burr, and the application with high processing requirements does not need to be cut twice. In addition, because of the servo follow-up fixed length tracking technology, the cutting length accuracy is higher than that of the ordinary flying saw. In the production process, dust and noise pollution are obviously reduced.

The whole system is fully digital intelligent control, which can control the main parts such as saw blade and moving saw accurately and has perfect protection measures. Based on servo technology, a number of innovative control strategies are adopted to simplify the field operation. The central computer control system can integrate any individual needs of customers, and control the processes before and after the production of welded pipes in a centralized way. The more advanced system can record the shift / daily production, batch, alarm, fault, operator and other information, and even use modern communication means to send these information directionally.
