Clean, low temperature coolant in large quantities, directed to the proper location, is necessary for a successful disc grinding operation.

Coolant problems are magnified in disc grinding due to the greater contact areas and greater power inputs than in a similar operation using the periphery of a grinding wheel.

Machine manufacturers provide several means of introducing coolant directly into the grinding zone. Nozzles can direct a flow of coolant between the discs. Fittings can be attached to the ends of some spindles to send coolant through the spindles and out through the center hole of the abrasives.

As production rates and stock removal increase and the tolerances become tighter, the control of the coolant becomes more critical. For a successful disc grinding operation, make sure that the coolant is cool and that the distribution system is functioning properly.
