Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.
