Friction and wear testing machine
It can perform flat grinding, curved grinding, edge grinding, folded edge grinding, and abrasion resistance tests such as anti-frosting, edge sealing, and pilling. The tested samples can be in a dry state or immersed in water, oil, or other liquids. It can be used for woven fabrics, knitted fabrics, coated fabrics, pile fabrics, socks, felt, non-woven fabrics, deep-pile fabrics, yarns, threads, plastic films, rubber, leather, paper, and many other materials.
Application
Petrochemical: Used to assess the long-term wear resistance of lubricating oil and grease, and to develop a variety of high-grade series of hydraulic oil, internal combustion engine oil, gear oil and other products.

Accessoriess
Friction pairs: such as four-ball, pin-on-disk, thrust ring, and ring-block configurations, used to simulate different friction and wear conditions.
Loading device: such as spring-type force application systems and lever loading systems, used to apply test force to the friction pair.
Driving system: including motors and reduction gears, used to drive the movement of the friction pair.
Sensors: such as test force sensors, friction force sensors, and temperature sensors, used to measure key parameters during the test process.
Oil bath and heater: used to simulate wet friction environments; the oil bath can hold lubricating oil or other liquid media, and the heater can control the test temperature.
Other accessories: such as chucks, tie rods, screws, springs, and nuts, used for the assembly and debugging of the testing machine.
Test Procedures
Preparation:
Determine the type of friction pair for the test and machine the samples according to the drawings.
Clean the samples, lower disc, and fixtures to ensure they are free of impurities.
Powering on:
Turn on the testing machine's power supply, start the control computer, and preheat the equipment for 10 minutes.
Sample installation:
Install the prepared samples into the corresponding fixtures, ensuring they are securely clamped.
If conducting a heating test, connect the temperature controller and temperature sensor.
Parameter setting:
According to the test requirements, set parameters such as load and speed, ensuring they meet the test standards.
Starting the test:
Press the start button to begin the test; the time and cycle count will begin.
By following these steps, the friction and wear testing machine can be used correctly, thus obtaining accurate test
