Abstract:
The present invention relates to a cutting oil composition, and is intended to provide a cutting oil composition, which is remarkably excellent compared with a conventional cutting oil composition in view of layer separation, dispersibility, viscosity, the time of ingot washing after sawing, and the degree of wafer warpage after sawing. The cutting oil composition of the present invention contains a mineral oil represented by chemical formulas 1 to 3 and highly hydrogenated, bentonite clay as a thickener, and glycerine tri oleate as a dispersant. The present invention relates to a cutting method using the cutting oil composition.
