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
