Closed-loop loading control enabling real-time force regulation and automatic generation of friction force versus load or speed curves

Support for additional modules including scratch, indentation, and friction testing

Accessories

Rotational friction and wear test module

Linear reciprocating friction and wear module

Scratch testing module

Indentation and hardness testing module

Vacuum and inert gas control components

Test Procedures

Install the required test module according to the test objective.

Mount the specimen and counter body securely inside the vacuum chamber.

Set test parameters including load, speed, temperature, and environment type.

Evacuate the chamber to the specified vacuum level or introduce inert gas as required.

Start the test and monitor friction force, load, and temperature in real time.

Complete the test based on predefined conditions or test duration.

Record and export test data for further analysis.

Maintenance Information

Regularly inspect vacuum seals, pumps, and fittings to maintain stable vacuum performance.

Clean test modules and contact components after each test to avoid contamination.

Periodically calibrate force sensors and temperature control systems.

Maintain vacuum and molecular pumps according to operating hours and manufacturer guidelines.
