12%The friction pairs of both bearing steel-fixed abrasive and bearing steel-brass were easily clogged, leading to dramatic changes in the sliding friction coefficients, and neither fixed abrasive nor brass was found to be a suitable material for grinding discs. Thus, PMMA and PTFE were selected as the materials for upper and lower grinding discs.

A bond is an abrasive material used to held abrasive particles together. The bonding material does not cut during the grinding operations. Its main function is to hold the grains together with varying degrees of strength. The different standard grinding wheel bonds are vitrified, resinoid, silicate, shellac, rubber, and metallic.

Grinding Recommendations for Tool Steels Many tool steels are specifically designed to resist wear in service. The presence of vanadium, molybdenum, tungsten and chromium promotes the formation of hard carbide particles throughout the matrix. Because they contain hard carbides, such wear-resistant tool steels often prove to be difficult to grind.

The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held together in the porous structure of the grinding wheel by a bonding substance (bond).
