Nozzles inside the grinding machine typically produce enough coolant flow, but quite often the pressure isn't high enough to be fully effective. As the wheel rotates, a layer of air forms around it, making it harder for the coolant to get directly into the wheel's pores and, therefore, into the grinding zone.
