Microcomputer controlled four-ball friction and wear testing machine
Microcomputer-controlled electro-hydraulic servo four-ball friction and wear tester This machine mainly evaluates the load-bearing capacity of lubricants under extremely high point contact pressure conditions in the form of sliding friction. It includes three indicators: maximum non-seizure load PB, sintering load PD, and comprehensive wear value ZMZ. The machine can also perform long-term anti-wear tests on lubricants, determine friction coefficients, and record friction and temperature curves. The machine is equipped with a high-precision measuring device that can measure the size of friction pair wear spots, or realize computer screen display, measurement and recording of friction pair wear spots.
