Model NDW Series Computer Control Torsion Testing Machine

Main Applications:

This testing machine uses Computer-controlled AC servo system and is loaded through the active clamping head driven by the AC servo motor and cycloidal pinwheel reduction motor. The torque and torsion angle are measured with high-precision torque transducer and photoelectric encoder. Computer will dynamically display the test 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, or industrial enterprises.

Main Functions and Features:

Loading mode: use imported AC servo motor and driver;

Testing of torque and torsion angle: high-precision symmetrical torque transducer for torque testing and high-precision photoelectric encoder for angle testing;

Operation: manual control and computer control;

Use WINDOWS-based supervision software to calculate mechanical indexes of materials. Auto process test data, dynamically display testing curve, store, and print the testing results. Operator can intervene in the analysis process and thus improve the analyzing accuracy.
