The present invention provides a method of minimal quantity lubrication cutting and grinding that can improve cutting and grinding properties and extend the life of tools. The minimal quantity lubrication cutting and grinding method of the present invention comprises supplying a compressed fluid containing 0.1 to 15 percent by volume of oxygen together with a cutting and grinding oil (particularly preferably an oil composition comprising an ester) to processing spots of a workpiece.

Method of minimal quantity lubrication cutting/grinding processing and oil composition used therefor

Cutting or grinding oil compositions which are suitable for use in a minimal quantity lubrication system in which a minimal quantity of an oil is supplied to the spot to be cut or ground of a work, together with air are reduced in stickiness and improved in lubricity.
