Applications & Features
NDW Series Computer Controlled Torsion Testing Machine provides loading and weighing capabilities in both rotation directions, which makes it possible to conveniently determine not only the ultimate torque of a specimen, but also the specimen behavior under continuous or intermittent torque loading in both directions. Computer can dynamically display the torsion curve, loading speed, peak value, and so on.
It is mainly used for the torsion test of metal and non-metal materials, as well as the torsion test for parts and components. It is an essential instrument to measure torsion properties of materials for mechanics laboratories of aviation industry, construction industry, scientific research dept, universities and industrial enterprises etc.

 Adopting PC-controlled Japanese AC servo system, it is loaded through the active clamping head driven by the AC servo motor and cycloidal pinwheel reduction motor.
 High-precision symmetrical torque transducer to measure test torque and high-precision LEC model photoelectric encoder to measure torsion angle;
 Double control modes: manual control and computer control;
 WINDOWS-based supervision software used to calculate mechanical indexes of materials. Automatic test data processing, dynamic display of test curves, storage and print out of test results. Operator can intervene the analysis process to improve the analysis accuracy.
 The computer can dynamically display the torsion curve, loading speed, peak value etc.
