Operation:
Firstly,prepare the accessories and test samples;
The first testing method:Five Finger Scratching Method
Load the weight onto the top of the shaft rod;
Install the scraping finger at the bottom of the shaft;
Fix the test sample on the testing platform and secure it;
Lower the connecting rod to allow the scraping head to come into contact with the specimen;
Set parameters on the display screen;
Conduct friction testing between the scratch head and the specimen;
The second testing method:cross scraping method
Install weights and scraping heads;
Mount the test sample;
Set parameters on the display screen;
Conduct friction testing between the scratch head and the specimen;
After the experiment,analyze and compare the samples to evaluate the surface scratch and durability of the material.
