Machining 101: What is Grinding? | Modern Machine Shop

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.
