7 Key Factors in Choosing a Grinding Wheel | Modern ...

The horsepower of the grinding machine can play a role in determining the grade of the bond or the hardness of the wheel. When a machine has a higher horsepower available at the spindle, harder wheel grades are wiser. The harder wheel will hold form and retain the grains as long as possible under the stronger forces.

Critical Coolant Factors in Roll Grinding | Norton Abrasives

The coolant viscosity should be low enough so the fluid easily floods the grinding zone. Coolant surface tension should be low so grinding swarf can settle and filter out. Before roll grinding begins, any personnel involved in the operation must read the coolant's safety data sheet (SDS) so they understand how to safely handle the fluid.
