MMG-2W microcomputer controlled high-temperature friction and wear testing machine

This testing machine is mainly used in the form of sliding or composite friction to evaluate the friction and wear performance of engineering materials such as metals, nylon, plastics, coatings, rubber, ceramics, rocks, molybdenum disulfide, and their surface modified treatments. According to user requirements, various forms of point, line, and surface friction pairs such as pin disks and ball disks can be equipped. Other forms of friction pairs can also be developed based on the installation interface size of the machine according to user requirements or by the user themselves for basic research on friction and wear, as well as research on testing methods. This machine is suitable for tribology research and other professional fields, and has a wide range of applications in departments such as petrochemicals, colleges, and research institutes.

The machine consists of a base and frame, a spindle and its AC servo drive system, a friction pair disc and sample clamping device, a closed-loop servo application system for test force, electronic measurement systems for various test parameters, a computer and data acquisition board, and dedicated control software. The drive of the spindle consists of an AC servo motor and its control system, which can achieve constant force and torque output throughout its entire speed range, and can work smoothly at extremely low speeds. This achieves stepless speed regulation of the spindle over a wide range, meeting the needs of different researchers.
The application of experimental force adopts a closed-loop servo system, and its size is set by the operator on the computer interface. The application is smooth and reliable, thus avoiding the influence of experimental force fluctuations on the test results. In order to reduce the friction during the up and down movement of the test friction pair and improve the accuracy of friction force (torque) measurement, linear bearings are used for guidance and supported by deep groove ball bearings; The spindle speed, rotation speed (test cycle), test force, friction torque (friction coefficient, friction force), friction pair temperature, test time and other parameters of the machine are all controlled by a computer. Real time test data is collected and corresponding test curves can be drawn. The data can be stored, retrieved, printed and output arbitrarily, and is true and reliable without human influence. After the friction test is completed, the following test results can be provided: friction coefficient, wear mass (to be weighed and input data), wear height (to be measured and input data), friction work, friction coefficient time curve, temperature rise (temperature) time curve, environmental temperature and other test parameters and curves. And it can store and print test reports.
