What is the use of friction and wear testing machine?

Friction and wear tester, also known as friction tester and wear tester. According to the load range, it can be divided into ultra-nano friction and wear tester, nano friction and wear tester, micro friction and wear tester (10N) and large load friction and wear tester (1000KN). According to the mode of friction movement, it can be divided into linear reciprocating friction and wear tester, high-speed linear reciprocating friction and wear tester (vibration friction and wear tester), rotary friction and wear tester, high-speed rotary friction and wear tester and linear rotary combined friction and wear tester. According to the friction pair, it can be divided into ball disk friction and wear tester, pin disk friction and wear tester, disk friction and wear tester, ring block friction and wear tester, four-ball friction and wear tester, cylinder liner piston ring friction and wear tester, high-frequency friction and wear tester, high-temperature friction and wear tester and vacuum friction and wear tester. Uses: Four-ball friction and wear tester and microcomputer-controlled electro-hydraulic servo friction and wear tester are widely used in oil friction in the market; Vertical universal friction and wear tester is used to evaluate the long-term wear resistance of lubricating oil and grease and the friction and wear performance of metal materials; The annular friction and wear tester is used to evaluate the lubrication performance of various lubricants in the form of sliding friction under the condition of oil infiltration and sliding; The high-temperature end-face friction and wear tester is used to measure the temperature rise and friction coefficient of materials and display the end-face friction and wear tester on the screen.

Working principle: the layer to be ground of the sample and the friction paper rub each other at a specified speed under the action of the load friction body. The wear resistance of ink layer (or coating) can be judged by measuring the decrease of density (or coating thickness) before and after rubbing. Structure principle of friction testing machine: microcomputer control, LCD dynamic display and mechatronics principle are adopted to carry out the set friction test. Input the test standard requirements or the number of rubs determined by the operator into the control system before the test, and the test can be automatically controlled, and the buzzer will prompt after each test. The control system has power-off memory function, that is, after each power-on, the parameter state entered before the last power-off is maintained. The actuator uses high-precision gear reduction micromotor to drive the friction body to do linear reciprocating friction motion.
