一、 Main purpose

◇ The vertical universal friction and wear testing machine can achieve friction simulation tests between different friction pairs under various conditions, such as changing temperature, load, speed, friction pair material, friction pair surface roughness, hardness, and changing lubrication status (no oil lubrication, drip oil lubrication, or immersion lubrication).

◇ The vertical universal friction and wear testing machine can simulate the friction forms of rolling, sliding, and rolling sliding composite motion, and has various friction pairs, such as pin disc (with large and small discs, single needle and three needle) friction pairs, four ball friction pairs, thrust rings, ball discs, etc. Able to complete various friction simulation experiments on points, lines, and surfaces. It can be used to evaluate the friction and wear performance of materials such as lubricants, metals, coatings, coatings, rubber, ceramics, etc.

◇ The vertical universal friction and wear testing machine is suitable for various professional fields of tribology, and can meet the requirements of friction and wear testing for users in various industries such as petrochemicals, machinery, energy, metallurgy, aerospace, and other tribological research, such as the development and testing of various high-end series of oil and grease products, as well as the development of emerging materials and new process research.
