Abrasive wheels are commonly used to improve the sharpness of cutting tools. The finer the abrasive wheel, the smoother the finish on the workpiece. However, this will be at the expense of heating up the workpiece.
So for soft materials, and rapid removal of material, use a coarse grinding wheel.
For hard materials and to obtain a fine finish on the material use a fine grinding stone. For the finest work, diamond or Boron nitride are often used.
Coolants are often used, and these may actually ease the grinding action.
