Flying Friction Saw
Flying saw serves as the key equipment in the ERW mill and cold rolling mill. It could perform high precision cutting while the pipes and profiles are moving at high speed. It mainly consists of control system, drive system, mechanic body, hydraulic and pneumatic system.

Flying Saw All Digital Control System
- Utilizing the world leading 32-bit module capable of nano-second data processing with
response speed four time faster than the forming module, thus the leap of the control system of cut-off machine from analogue control to digital control realized.
- Latest coding digital processing technology can improve the precision of encoders by over
10 times.
- The whole controller is of compact structure with less electron components. SMA technology
is adopted for all the core components, making the system more aseismatic and totally free from the potential trouble caused by loose connection.
- Various communication ports are available for convenient connection and communication
with the other equipment.
