Computer-Controlled Torsion Testing Machine (500 N·m)

The system operates on a Windows-based Chinese interface, enabling multiple  control modes for torque and angle. It uses a graphical window-based interface,  allowing configuration of display screens and operation panels, setting of test  speed and various control parameters, real-time display of basic test results,  and real-time display of various parameter curves during the test process.

Application

This computer-controlled torsion testing machine is mainly used to test the  torsional properties of materials and components such as metal bars, drive  shafts, bolts, fasteners, springs, rotating shafts, and medical implants. It  measures torque, torsion angle, yield torque, and fracture torque, and is used  for mechanical property testing and torsional failure verification of  components. It is widely used in machinery, hardware, automotive, military, and  research laboratories. The system provides multiple test curves, including  torque–angle, torque–time, and angle–time. Users can adjust the test program  according to actual needs, and operation is convenient. The testing machine is  equipped with overload protection. The computer control system enables automated  control of the test process, data processing, and export of test reports.

FAQ

1. How do I choose the appropriate torque range for my application?

The maximum torque should be selected based on the expected failure torque of the specimen. It is recommended that the working range falls within 20%–80% of full scale to ensure measurement accuracy and sensor longevity.

2. What factors affect the accuracy of torsion test results?

Key factors include specimen alignment, clamping stability, sensor calibration, and test speed. Improper installation or excessive vibration may introduce measurement errors, so correct fixture selection and calibration are essential.

3. Can the machine handle both brittle and ductile materials?

Yes. The system supports different test modes and speed settings, allowing it to evaluate both brittle fracture behavior and plastic deformation in ductile materials.

4. How is torsional strength calculated during the test?

Torsional strength is calculated automatically by the software using the measured torque and specimen geometry. Users only need to input relevant dimensions before testing.

5. Is it possible to customize test procedures for different standards?

Yes. The software allows users to define test parameters such as loading speed, control mode, and stop conditions, making it adaptable to various industry or internal testing standards.

6. What happens if the specimen breaks during testing?

The system detects a sudden drop in torque and automatically stops the test to protect the equipment and ensure data integrity.

7. How are historical test results managed?

All test data and curves are stored in the database and can be searched, reviewed, and re-analyzed at any time. Reports can also be exported for documentation or comparison.

8. Does the machine require regular calibration?

Yes. Periodic calibration of the torque sensor and verification of angle measurement are recommended to maintain long-term accuracy and compliance with testing requirements.

9. What types of fixtures are available for different specimens?

Standard three-jaw chucks are included, but special fixtures can be customized for non-standard shapes such as thin wires, medical implants, or irregular components.

10. How does the system ensure safe operation during high-load testing?

The equipment is equipped with overload protection and monitoring functions. It automatically stops under abnormal conditions such as excessive torque, ensuring operator and equipment safety.
