Grinding Wheels. Grinding wheels have two major components: the abrasive grains and the bond. The relative percentages of grain and bond, and their spacing on the wheel, determine the wheel's structure. Different types of grains work better on different projects, as do different types and "grades" (i.e. strengths) of bond.
Since the material is easy to grind, grains shouldn't break down too soon or too easily, so the whole grain can be used to maximize wheel life. A coarser grit is best for these materials, as the grains can easily penetrate the material and maximize stock removal. A harder grade (that is, a harder bond between the grains and the wheel) also ...
