Test Procedures
Mount the test specimen securely on the worktable.
Select the appropriate contact geometry, such as scratch needle or ball indenter.
Configure test parameters including speed, load range, and test mode via the control interface.
Start the test to apply friction motion under variable or constant vertical load.
Record real-time friction force and displacement data during operation.
Generate three-dimensional wear maps showing the relationship between load, friction force, wear depth, and wear cycles.
Identify critical load values corresponding to wear transitions based on test results.
Maintenance Information
Keep the gear and rack drive system clean to ensure smooth motion
Inspect load sensors and displacement sensors regularly for accuracy
Replace scratch needles or ball indenters when wear affects measurement reliability
Verify electrical connections and safety protection devices periodically
Store software, accessories, and calibration weights in a clean, dry environment
