If you do a search on this site using the key words grinding coolant you will find some recommendations. your requirements are coolant stability with infrequent use, mixed metal corrosion inhibitors, a water base and safe for disposal in a municipal sewer. the last requirement may not be possible with a semisynthetic or soluble oil based coolant.

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.
