High Frequency Friction Machine

The High Frequency Friction Machine is a reciprocating tribological testing instrument designed to study high-frequency friction, wear, and tribological behavior of metals, ceramics, and composite materials under dry or lubricated conditions. You can apply controlled loads up to 1,000 N over a maximum stroke of 25 mm while precisely controlling frequency, temperature, and test sequence via PC interface and dedicated software. The system has been validated through multi-laboratory comparisons during ASTM G133 and ASTM G181 standard development, ensuring high reliability and international recognition.
