    - Grinding wheels are made of fine grains of abrasive materials having sharp edges.

    - The performance of grinding wheel is evaluated in terms of grinding ratio (G)

    - The grinding ratio is defined as the ratio of the volume of material required to the volume of wheel wear

    G = (the volume of material required) / (the volume of wheel wear)

    - The value of grinding ratio is usually about 10 to 60 for fine grinding operations like horizontal surface grinding.

    - Whereas, for rough grinding operation, the value of grinding ratio is much less than 10.
