    OverviewProcessesGrinding wheelLubricationThe workpieceSee also

    Selecting which of the following grinding operations to be used is determined by the size, shape, features and the desired production rate. Surface grinding uses a rotating abrasive wheel to remove material, creating a flat surface. The tolerances that are normally achieved with grinding are ±2×10 inches (5.1 μm) for grinding a flat material and ±3×10 inches (7.6 μm) for a parallel surface.
