NDW Series Computerized Torsion Testing Machine Spring Screw Bolt Torsion Testing Machine
Main function
The loading system of this machine, controlled by computer, rotates load through alternating servo motor and cycloidal gear reducer. Torque and twist angle detection uses the high-precision torque sensor and a photoelectric encoder; computer displays dynamically the curve of test torsion angle and torque, rate of loading, peak of power and so on.
