Coolant flow in surface grinding with non-porous wheels ...

Abstract A parameter that is often used in the assessment of cooling efficiency in grinding is the amount of fluid that flows through the grinding zone. This paper shows that when grinding with wheels possessing no bulk porosity, only a portion of the flow through the grinding zone is effective. Even at the highest wheel speeds employed, it is observed that ample fluid travels on the wheel ...

In Grinding, Coolant Application Matters - SME

I use a flow rate based upon the grinding power created during the process, because the more aggressive a cycle is, the more coolant is applied. With conventional abrasive wheels, a flow rate of 2 gpm/hp is effective. For superabrasive wheels, a flow rate close to 1 gpm/hp (3.8 L/min/hp) works well.
