1. Different forms of wear

The depressed grinding disc in stock wears wear and wear in two forms. A represents wear and wear, and B and C represent broken wear discs representing the shedding of abrasive particles.

2. The cause of grinding disc wear

The depressed grinding disc in stock wear and wear. The high degree of mass in the workpiece causes mechanical wear of the abrasive particles, which is very serious when grinding certain hard-to-grind materials.

The depressed grinding disc in stock oxidation wear. Oxidation grinding in the air promotes. Grinding experiments conducted in a vacuum found that corundum grinding discs were much more difficult to grind low carbon steel than in air. This is because the convection of the air causes the grinding temperature to decrease and the oxygen in the air rapidly oxidizes the newly formed surface of the workpiece to form an oxide film, which reduces the possibility of adhesion of the abrasive. For some abrasives, the surface will be at a high temperature. Oxidation occurs, causing it to be gradually consumed, which is oxidative wear.
