Features

Linear motion driven by a servo motor ensures stable and precise friction testing

Balanced mechanical arm structure minimizes the influence of adapter weight on vertical load

Direct transmission of friction force to the load sensor improves measurement accuracy

Supports a wide range of test heads and accessories for versatile surface performance evaluation

Touchscreen interface enables intuitive operation and real-time data display

Capable of testing under special environments, including lubricated, heated, or cooled conditions

Test Procedures

Fix the test specimen securely on the worktable.

Select and install the appropriate test head according to the test method.

Set test parameters such as speed, sliding distance, load, and motion mode.

Adjust environmental conditions if required (oil, heating, or cooling).

Start the test and monitor friction force and surface behavior in real time.

Complete the test automatically or manually after the preset conditions are met.

Analyze test results based on the applicable standard and test objective.

Maintenance Information

Clean the worktable and test heads after each test

Inspect mechanical arms and transmission components regularly

Verify load sensor performance and zero calibration periodically

Keep electronic components free from dust and moisture

Store accessories and weights properly to prevent damage
