  • Basic Grinding Theory 221Tooling U-SME

    "Basic Grinding Theory" provides an overview 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.
