The torsional moment applied by the torsion testing machine to the specimen is balanced by the weighing mechanism connected to the fixed chuck, while simultaneously driving the load pointer to rotate and indicate the magnitude of the torsional moment.

Rotate the handwheel to apply load; a high-precision torque sensor detects torque, an optical encoder detects the torsion angle, and the LCD screen displays the test results. This material torsion testing machine features a simple structure, convenient and flexible operation, and low cost, making it primarily suitable for mechanical laboratories in research departments, various universities, and industrial and mining enterprises to determine the torsional properties of materials.

Xi'an LETRY specializes in manufacturing the WNZ series of microcomputer-controlled torsion testing machines, mainly used for testing and researching the torsional mechanical properties of metal materials and their components. This testing system employs high-quality AC servo motors and fully digital microcomputer servo speed control technology, ensuring system stability and excellent performance, keeping pace with global standards. It automatically tracks and measures the torsion angle of materials, maintains peak values, automatically processes test data, digitally displays torque values, torsion angles, loading rates, and T-φ test curves, and prints T-φ test curves as well as test reports compliant with national standards, including T, τb, and shear modulus G of materials.
