Multi-Four Ball Test Machine
EnM4 (Four-Ball Tester)gineered Lubricants was the first company in the country to employ the Multi-Four Ball Test Machine. The machine combines both the Four-Ball EP and the Four-Ball Wear testers into one computer-operated machine. Increasing demands in tribology testing have required the need for higher accuracy of controlled variables, increased reproducibility and repeatability, more dynamic ways to uncover data, and more control capacity. This new machine is based on a revolutionary new concept, which linearizes the specimen-applied load in both wear and extreme pressure thresholds. This linear loading concept broadens the machine’s capabilities and accuracies as well as the spectrum of test evaluation. Test variables include load, RPM, time and temperature.
