  • Basic Grinding Theory 221 Tooling U SME

    Basic Grinding Theoryprovides anoverview of the general process of grinding. Grinding occurs at the point of contact between an abrasive wheel and a workpiece. Like any other cutting process, grinding removes material in the form of chips. In order for a wheel to grind properly, its abrasive grains must wear and self-sharpen at a consistent rate.
