APPARATUS FOR PRESSURE SUPPLY OF CUTTING FLUID Russian patent published in 2003 - IPC

FIELD: technological processes in machine engineering, machine tool manufacture, possibly pressure supply of cutting fluid through pores of grinding disc with axially shifted cutting layer. SUBSTANCE: apparatus includes nozzle with supplying branch pipe and cylinders arranged around nozzle, communicated with it through radial and draining ducts and shifted in axial direction one relative to another. Cylinders have pistons with sealing collars and rods rested upon ring secured to stationary casing. At working operation when each next pressure cylinder passes its low position, intensive jets of cutting fluid are directed onto worked surface due to additional injection. Said jets have high motion speed relative to worked part. EFFECT: improved design allowing to enhance efficiency due to changing inclination angle of abrasive disc, to optimize thermal stress of process at working different materials, improved quality of ground parts due to oscillation of cutting zone and additional directed injection of cutting fluid through pores of disc to contact zone. 2 cl, 3 dwg
