The coolant in fact cools the workpiece and avoids the pincusion effect and raised ears after the part cools as well as the plate expanding up into the wheel cause the issues this person had. Coolant cannot just be a drip--it has to have a good flow rate since heat is produced fast while grinding so you need the volume.

a water coolant grinding machine Bendigo Cylinder . aug 11 2021 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 ...
