CUTTING/GRINDING METHOD USING EXTREMELY TRACE AMOUNT LUBRICANT AND OIL COMPOSITION FOR CUTTING/GRINDING PROCESSING USING EXTREMELY TRACE AMOUNT LUBRICANT

摘要

PPROBLEM TO BE SOLVED: To provide a cutting/grinding method capable of achieving improved cutting performance and a long tool life in cutting/grinding processing using an extremely trace amount lubricant. PSOLUTION: In the cutting/grinding method using the extremely trace amount lubricant, compressed fluid having 0.1-15% by volume of oxygen is supplied together with a cutting/grinding lubricant (more preferably an oil composition containing ester) to a machining area.
