Pin-on-disk wear testing, as a classic experiment in tribology, is dedicated to studying friction, wear, and lubrication. This standardized approach is widely used to understand the performance of materials under sliding contact. The test typically involves a pin, usually made of durable materials, pressed against a rotating disk, where the two can wear against each other under controlled conditions. Understanding the wear rate and friction coefficient is crucial for many industries (from automotive to aerospace) as it provides insights into material performance and lifespan.

UT1054A Flat / pin disc friction wear testing machine is mainly used to determine the friction properties of slide rails and specific metals at approximate PV values. In addition, the machine can also be used to evaluate the friction and wear performance of lubricants, metals, plastics, coatings, rubber, ceramics and other materials under the condition of high linear speed.

ASTM G99-23 : Standard Test Method for Wear and Friction Testing with a Pin-on-Disk or Ball-on-Disk Apparatus

Main structures: 

2.1 The testing machine is composed of a normal loading system, a horizontal lever, a torque force measurement system, a temperature control system, a cooling and lubrication device, an electrical control cabinet and a computer real-time data acquisition and control system (including software).

The main engine of the testing machine is mainly composed of the main engine base, the horizontal machine base, the normal spindle and its driving system, the test force application device, the friction torque and displacement high-precision sensing measurement system, the test force measurement and the friction temperature measurement system. The normal loading system of the testing machine adopts lever + weight, which has high precision and good reliability; The horizontal loading system adopts linear motor as the loading system, the control accuracy is high, the corresponding is fast, the host base adopts a larger mass of iron castings, the natural frequency is high, the shock absorption and seismic performance is good, and the box seat is also made of iron parts after CNC boring processing, the electric spindle is firmly locked in the box base, which can improve the stability of the loading work.

2.2 The function of the cooling and lubrication device is mainly to cool and lubricate the actuator, so that the actuator can work stably and reliably for a long time. (Suitable for oil testing)

2.3 Computer real-time data acquisition and data processing control system is an intelligent system that is specially prepared for the control software to artificially set, collect, monitor and output various test parameters, which can avoid the human influence of the test results and improve the accuracy of the test results.

2.4 The measurement of friction force selects the high-precision force sensor of the American Celtron brand;
