FIELD: production processes.
SUBSTANCE: invention refers to abrasive treatment and can be used in grinding operations of workpieces for supplying lubricant coolant to internal grinding zone. Device contains nozzle arranged in the space formed with working surface of abrasive wheel and treated workpiece surface. Nozzle is crescent-shaped and provided with two slot holes with possibility of simultaneous supply of lubricant coolant through them by being sprinkled to hydrodynamical wedge zones formed in the above space and outlet of abrasive grains of abrasive wheel from cutting zone.
EFFECT: quality and efficiency of internal grinding of workpieces are improved.
