Application: The vertical universal friction and wear testing machine model MMW-1, is designed to develop all kinds of medium and high grade hydraulic oil and evaluate inspection testing machine, and the application and function is similar to FALE No. 6 multi-function testing and measuring testing machine. This machine is standard testing machine to evaluate anti-wear character for lubrication grease or oil with ASTM D 4172-82, ASTM D 2266-81. And also is standard apparatus for evaluating oil, with hydraulic lubricant, anti-friction character in general petroleum and chemistry industry Corporation. With XBE34007-87. the above method is used four ball friction couple measuring relative anti-wear character for lubrication agent under the special testing condition. It is widely used in developing anti-wear hydraulic oil products
