MMW-1A Computer controlled vertical universal friction wear tester
Application:
MMW-1A is a Multi-function Friction and Wear Testing Machine. It is designed for simulating, evaluating and testing almost all kinds of oil (high-class serial hydraulic oil, lubricant, combustion oil and gear oil) and materials (metal, plastic, coating, rubber, ceramic, etc. ).
It is widely used in tribology field, petrol chemical industry, mechanical, energy resource, metallurgy, space flight, engineering areas, college and institute, etc.
