Application
The Low-Load Wear Testing Machine is widely used in applications where ultra-low contact forces and high sensitivity are required, including:
Wear testing of thin films and functional coatings
Evaluation of surface-treated metals and micro-scale surface layers
Tribological testing of polymers, films, and soft materials
Wear behavior analysis of decorative and protective coatings
Research on micro-load friction and wear mechanisms
Typical test samples include:
Thin polymer films
Surface-treated metal sheets
Coated substrates
Functional and decorative coatings

Test Procedures
Mount the test specimen on the rotating table or vacuum chuck.
Install the appropriate upper fixture or scratch needle.
Set the required load using the leaf spring displacement mechanism.
Adjust the rotation speed and test duration.
Calibrate the load using the dedicated load cell if required.
Start the test and monitor friction and wear behavior.
Stop the test automatically at the preset cycle count and record results.
Maintenance Information
Clean the turntable and fixtures after each test
Inspect the leaf spring and load calibration components regularly
Verify displacement sensor accuracy periodically
Keep the drive and measurement units free from dust and vibration
Store accessories in a dry and stable environment
