一、 Main purpose
The lever type four ball friction and wear testing machine is a cost-effective laboratory evaluation equipment developed by our company to meet the needs of lubricant research and production users. The testing machine adopts the form of sliding friction and evaluates the bearing capacity of lubricants under extremely high point contact pressure conditions, including three indicators: maximum no bite load PB, sintering load PD, and comprehensive wear value ZMZ. This machine can also perform long-term wear resistance tests on lubricants, measure and display the friction coefficient in real-time.
This machine adopts a color touch screen control method, which can set and display the spindle speed, revolutions, test force, friction torque, friction coefficient, test time, temperature and other test parameters in real time. It can collect test data in real time and draw corresponding test curves.
