This paper is dealing with the identification of efficient cleaning nozzle configuration to prevent the wheel from loading in creep feed grinding. The properties of different cleaning nozzles types were analyzed in terms of jet velocity and jet impact on the wheel surface using high speed imaging and pressure sensitive sheets. In grinding experiments the cleaning efficiency of each nozzle configuration was evaluated by optical measurement of wheel clogging inside the machine tool. With this newly developed procedure of tool cleaning optimization a significant reduction of grinding forces (up to 30%) and of the tool wear (up to 20%) was achieved.
