In the form of sliding friction, the machine is used to evaluate the performance of engineering plastics, powder metallurgy, etc., and to determine the wear resistance and material matching characteristics of the materials under specified technical conditions. The test can be carried out by changing various parameters such as load, speed, time, friction mate material, surface roughness, hardness and test environment temperature. The computer can control the whole process of the test, and the system software can monitor the test process in real time, and record the relevant test parameters and curves.
