1. Product introduction
1. MMW-1 vertical universal friction and wear testing machine, its main purpose and function are similar to the American FALEX6# multi-specimen-test machine (Multi-Specimen-Test Machine), and it is similar to our company's MMW-1 vertical The purpose of the universal friction and wear tester is basically the same.
2. The vertical universal friction and wear tester has the friction form of rolling, sliding or sliding composite motion under a certain contact pressure, and has a stepless speed regulation system, which can be used to evaluate lubricants at extremely low or high speeds , Metal, plastic, coating, rubber, ceramics and other materials friction and wear properties, such as low-speed pin disc (with large disc and small disc, single needle and three needle) friction function, four-ball long-term wear resistance and four-ball rolling contact fatigue, Ball-bronze three-piece lubrication performance, as well as thrust washers, ball-disk and stick-slip friction performance tests.
