1.Application:

MMU-2 High Speed End face Friction and Wear Testing Machine is used for testing the friction capabilities of project plastics, powder metallurgy and alloy bearing under the sliding friction at different speed. It operates under the conditions of room temperature or high temperature and changing all the parameters such as lubricant state (non-oil lubrication or oil soaking lubrication), load, speed, friction spouse material, roughness of friction subsurface and hardness, etc. It also can be used to test the temperature and frictional coefficient of materials.
2.Features

1) It is a hydraulic-mechanical integration precise testing machine.

2) It is equipped with plunger pump and cogwheel pump as the power source. the overflow valve, throttle valve, reversing valve are all original from Taiwan.

3) the hydraulic jar is equipped with frictionless plunger cylinder which can ensure accurate transmitting data.

4)the spindle motor is equipped with Panasonic AC servo motor and controller to ensure wide speed range, wide low speed torque, and low noise.

5) the alarming lamp will shine and spindle motor will stop when any parameter is more than preset parameter.

6) Digital device and PC screen can display all the parameters, and record temperature-time curve, friction-time curve.

7) Equipped with high precision measuring device, it can measure the size of vice friction spots.
