Factors affecting proper coolant application when grinding ...

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.

THERMAL DAMAGE IN GRINDING

It is apparent from figure 7 that by reducing the fluid temperature from 40° to 20°C, the critical power flux could be raised by a factor of 2. (Similar results were obtained in simulated grinding tests by Powell et. al., 1978) Similarly, the supply pressure to a fluid jet affects the removal of heat from the grinding zone.
