G612 national standard shoe wear testing machine
The whole shoe wear testing machine is used to test the wear resistance of soles and sole pieces. The principle is to press the rotating grinding head vertically above the sample, and carry out rotary wear test on the test sample at a certain load weight and a speed of 191r/min. After the test is completed, the wear length of the sample is measured to evaluate whether the sample is qualified.
