MZK-5 High-Temperature Vacuum Friction and Wear Testing Machine

1. Main Functions

MZK-5 High-Temperature Vacuum Friction and Wear Testing Machine. Under certain contact pressures, this machine can perform rolling, sliding, or combined rolling-sliding friction tests under conditions such as abrasive, high-temperature, ambient-temperature, and atmosphere protection. It features a stepless speed regulation system and can be used to evaluate the friction and wear properties of lubricants, metals, plastics, coatings, rubber, ceramics, and other materials under very low or high speeds. The machine offers extensive flexibility in friction pair configurations, including low-speed pin-on-disk (with large and small disks, single and triple pins), four-ball long-duration wear resistance, four-ball rolling contact fatigue, ball-bronze lubrication performance, thrust washer, ball-on-disk, slurry wear, and stick-slip friction tests.

2. Control Methods and Software Features

The MZK-5 high-temperature vacuum friction and wear testing machine is a precision机电液一体化 (mechanical, electrical, and hydraulic integrated) instrument. It uses an imported hydraulic pump as the power source. The relief, throttle, and directional control valves are originally imported from Taiwan and self-developed proportional valves. The hydraulic cylinder adopts a frictionless piston cylinder to ensure accurate force measurement. The spindle motor employs a servo-integrated speed control system and motor, offering stable speed, high torque, wide speed adjustment range, and low noise. Measured parameters include test force, frictional force, test time, and test cycle (spindle revolutions). These four parameters can be preset according to the material being studied to achieve optimal performance. When any parameter exceeds its preset value, the corresponding alarm light turns on and the spindle stops rotating. All measurement results can be displayed in real time on the computer screen, with test curves recorded and saved.
