This instrument is designed as a whole and has four sample fixtures, which can test four samples simultaneously. By driving the connecting plate with a motor, the friction device installed with weights is driven to perform reciprocating friction motion on the sample, causing the sample to produce pilling or wear. The wear resistance performance of the sample under a certain pressure is tested, and the grade of the sample is evaluated, providing reference data for material selection.

This instrument is applicable to the following standards: ISO 5470

ISO 12945-2

ISO 12947-2

Maintenance and upkeep

1. Keep the instrument clean at all times, wipe the cylindrical shaft with a cotton cloth before and after each experiment to keep it clean.

If not used for a long time, please remove the test pressure plate and spray anti rust oil.

3. Add lubricating oil to the gear parts every month.

4. The turntable in the middle of the instrument is made of plastic, and the screw threads that fix the holes on it are prone to damage. Therefore, when changing between wear resistance testing and pilling testing, attention should be paid to protecting the screw threads of the turntable.

5. When using this instrument for testing, the curve drawn by the friction head is the standard Lissajous curve. The twisting of the guide plate, friction head guide shaft, and friction head itself will cause the friction head movement trajectory to no longer be the standard curve, which will have a negative impact on the test. Therefore, attention should be paid to protecting the integrity of all accessories.
