Microcomputer Controlled Vertical Universal Friction and Wear Testing Machine MMW-1A

Product description

The machine is mainly based on sliding, rolling and sliding friction type, in the lower contact pressure, the choice of different forms of friction, used to assess the long time of the lubricating oil, grease, and metal, plastic, rubber, ceramic, coating and other materials, friction and wear properties.. According to user's requirement, it can offer kinds of friction pairs, such as the ball plate, the ball three, the pin, the three column, the simulation cam, the gear and so on. The machine can measure the friction torque, calculate the friction coefficient, the computer automatic control, display the temperature - time curve, friction coefficient - time curve, the friction time curve, the speed time curve, the test force time curve, the friction torque time curve. The machine is equipped with high precision measuring device, which can measure the size of the friction pair, or display, measure and record the computer screen of the friction pair.
