The shear speed of the flying saw is directly related to the working efficiency of the hf-welded pipe production line. The accuracy of the saw cutting and the stability of the work have a direct impact on the quality of the hf-welded pipe production process, which is very important. It can be predicted that the flying saw plays a very important role in the hf-welded pipe production line.

The working process of the flying saw can be roughly divided into: tracking the progress of the unit, and conducting quantitative cutting of the continuous running steel pipe. In the whole working process, the whole system by computer, or flying saw the console to control, USES a dc speed regulation system, this systematic machinery can drive the actuators, finish cutting the car boot process, speed tracking, to track the tube speed is a very important initiative, in the follow-up work to clamping length cut off and return, waiting for this series of work flow.
