GRINDING FLUID FEEDING METHOD AND GRINDING FLUID FEEDING NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a grinding fluid feeding method capable of suppressing the retention of a grinding fluid near a machining point, allowing the grinding fluid to efficiently reach the machining point in the method of feeding the grinding fluid for lubricating and cooling the machining point of a workpiece by a grinding wheel when grinding the surface of a material to be ground. SOLUTION: The grinding wheel side side-wall of a nozzle 10 is brought close to the outer peripheral surface of a grinding wheel 14 to eliminate air flow swirling along with the grinding wheel 14, and the width of a tip part 18 of the nozzle 10 is narrowed to spray a grinding fluid convergently to the cross direction center of the grinding wheel 14. Grinding fluid flow in the cross direction of the grinding wheel 14 is thereby generated near a machining line to reduce a fluid retention part near the machining line.
