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.
