Grinding low-alloy tool steels seldom presents any difficulties. When grinding high-alloy tool and high-speed steels with high carbide content, however, problems can easily occur. For this reason, the grinding parameters must be selected carefully. The higher the wear resistance of a steel, the more difficult it is to grind.

Grinding fluid also acts as a coolant, and even oil has some heat-transfer capability, but not as much as water-based coolants. "Material removal is increased by the reduction in specific energy, which allows the stock removal rate to go up without increasing the surface damage to the workpiece," said Foster.
