The operating procedure of a Multi-Purpose Friction and Wear Tester may vary slightly depending on the specific model and configuration, but the core steps are largely consistent. A typical workflow is outlined below:
Inspect the equipment for any visible damage and ensure all components are intact. Confirm that the power supply, air source (if applicable), and cooling system (if required) are functioning properly.
Clean the specimen fixtures, friction pairs (such as pin-on-disc, four-ball, block-on-ring, etc.), and the workbench surface.
Prepare the test specimens according to relevant standards (e.g., ISO, ASTM, GB/T), ensuring that dimensions and surface roughness meet the required specifications.
2. Specimen Installation
Mount the upper specimen onto the main spindle chuck, typically secured using a tapered fit and locking rod.
Fix the lower specimen onto the counterface disk or specimen holder, ensuring proper alignment and firm installation.
For high-temperature or lubricated tests, install the heating system or lubricant supply system in advance.
3. Parameter Setting
Set the test parameters via the control interface (usually a 7-inch color touchscreen or PLC + computer system), including:
Test load: typically 0–1000 N, applied via weights, pneumatic, or motor-driven loading systems.
Motion mode: linear reciprocating (speed 1–400 mm/min) or rotational (speed 1–3000 r/min).
Test duration or number of cycles/strokes.
Environmental conditions: if heating is required, set the target temperature (room temperature to 150°C or higher).
Zero the sensors for friction force, load, and other measurement channels.

Activate the automatic loading system to stabilize the test load at the preset value.
Press the “Start” button to begin the test operation.
Monitor real-time data such as friction coefficient, temperature, and wear behavior (some systems provide live curve display on-screen).
5. Test Completion and Data Processing
After the test is completed, the system will automatically unload or can be manually set to “Unload.”
Once the spindle comes to a complete stop, lower the guide shaft and remove the specimen.
Export data via USB or software, typically in formats such as Excel, Word, or TXT.
Analyze wear scar morphology, mass loss, and friction coefficient curves to evaluate the wear resistance of the material.
