FAQ
1. What is this product?
The Electronic Torsion Fatigue Testing Machine is an instrument designed to perform static and cyclic torsion tests on materials and mechanical components.
2. What is it used for?
It evaluates torsional strength, fatigue life, and torsion behavior of materials under different torque or angle conditions.
3. How does it work?
The specimen is clamped between fixtures. A CNC servo motor applies torque through a planetary reducer, and sensors collect torque and torsion angle data. The system displays curves in real time and generates reports.
4. Why is it important?
Torsion testing ensures materials and components meet mechanical performance standards and reliability requirements for industrial, automotive, or aerospace applications.
5. What materials can be tested?
Shafts, rods, and mechanical components made of metals, composites, or other torsion-capable materials within the machine’s torque range.
