FIELD: process engineering.
SUBSTANCE: proposed invention relates to machine building and may be used in grinding with feed of lubricant-coolant in grinding zone. Proposed device comprises lubricant-coolant feed pipeline and crescent nozzle. Said nozzle is arranged in crescent space formed by grinding wheel surface and billet surface being ground and proved with two slit-like holes. Said slots are used to feed lubricant-coolant by spraying into hydrodynamic wedge zone and to discharge abrasive grains from grinding zone. Total area of two slit-like holes is smaller that feed pipeline cross section area.
EFFECT: higher quality and efficiency.
