Specifications

Computer controlled vertical universal friction and wear tester MMW-1

Computer Controlled Vertical Universal Friction and Wear Tester       
   

MMW-1 is a Multi-specimen 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 material (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.

Standard

this machine meets SH/T 0189-1992 Lubricant Anti-wear performance Evaluation Method (Four-ball tester method) and conforms to ASTM D4172-94 and ASTM D 5183-95.
