Customer Reviews
We`ve received machines yesterday!It was great to work with you! In attachment the thank-you letter for you and youк boss, that was signed by my CEO.

—— Барабан Григорий

We have had a good look at the glossmeter & we like what we see. The results are respectably close to specification calibration. We love it.

—— Dave Brewer

We have received the machine, thank you for being patient with me during this time, I haven't use it yet, but I am sure that it will be okay.

—— Jose Zikasky

Computer Controlled Vertical Universal Testing Machine Friction And Wear Tester

 

 

 

Brief introduction:

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.
