Studies on reduction of coolant in cylindrical plunge grinding

Effect of brush-nozzle on coolant flow around wheel surface

Abstract

This study deals with the reduction of coolant in cylindrical plunge grinding. A brush-nozzle is placed in order to block ′air-belt′ which is boundary layer on the wheel surface, and it helps the coolant adhere to the wheel surface. This study confirms that the quantity of coolant can be reduced from 10 l/min to 0.4 l/min by using the brush-nozzle. In addition, the brush-nozzle is effective in reducing grinding force and generation of smooth ground surface.
