Introduction to basic parameters of MD-2 multifunctional friction and wear testing machine:

This testing machine is used for testing the friction and wear performance of materials, material surface coatings, and component surfaces. Can provide a wide range of loads and rotational speeds. Experiments can be conducted on different friction pairs of ball disc and pin disc, and the computer can automatically detect under different friction modes,All tested parameters，Friction coefficient, friction force, load, and torque can all be measured during the experiment and displayed synchronously in the form of data and graphics.The installation environment control system can adjust the test temperature and ambient atmosphere for testing.

This instrument can be widely used in the research of material surface processing technology, evaluation of material failure and reliability, industrial product quality inspection and control.This device is equipped with automatic shutdown protection, easy operation, and high measurement accuracy.
