1. The loading is composed of precision ball screws, linear motion ball bearings, and force shafts, with low friction and minimal impact on the accuracy of the test force.

2. The test force sensor adopts a load sensor installed between the force shaft and the piston, which is sensitive to changes in the test force and has high accuracy in indicating the test force

3. The experimental force is controlled by servo motors, which have fast response to changes, high control accuracy, and minimal impact on the experimental results.

4. The measurement and control software is based on the Windows operating system and supports XP, Win7, Win8, and Win10 systems

5. The application of experimental force is controlled by a servo system, ensuring smooth and reliable application. The magnitude of the experimental force can be set by the operator on the computer interface.

6. The parameters such as spindle speed, rotation speed, loading force, and test time are all controlled by a computer, and real-time data such as friction force, friction coefficient, and test temperature are displayed. The test data can be collected and saved in real time, and the friction force can be plotted
