10～5000N.m Torsion Testing Machine
The NJW series torsion testing machine is composed of a loading system, a transmission system, a digital data acquisition and processing system, and a computer measurement control display system. It is suitable for static mechanical performance testing of various components such as transmission shafts, half shafts, etc. Test on the torsional mechanical properties of screws. The machine adopts horizontal structure.
Computer screen display, digital data acquisition control system and fully digital AC servo system form a closed-loop control. It adopts precision reducer transmission and has the characteristics of uniform loading, stability, no impact phenomenon, and accurate data acquisition and control.

Features
This machine is controlled by a computer, and the transmission system is controlled by a transmission loading servo system. It adopts a precision torque sensor, which has high measurement accuracy and good stability. The computer automatically displays test data such as torque, torque coefficient, torsion angle, loading rate, and test torque peak, and displays Test twist angle-torque, torque-time, twist angle-time curves; store and print test reports. (The ultimate torque, effective torque, torque coefficient, and torsion angle can be found.)
