Abstract:
1. A metalworking method of a material employing a water-soluble metalworking oil agent, wherein the water-soluble metalworking oil agent is prepared by blending the following components (A)-(D): (A) at least one selected from the group consisting of (a1) a condensed fatty acid obtained by dehydration-condensing a ricinoleic acid and (a2) a condensed fatty acid obtained by dehydration-condensing a monovalent carboxylic acid with an alcoholic hydroxyl group of a condensed fatty acid obtained by dehydration-condensing a ricinoleic acid; (B) an ester compound obtained by dehydration-condensing a monovalent or multivalent alcohol and a monovalent carboxylic acid; (C) an amine compound; and (D) water, wherein a blend ratio of the component A is 10 mass % or more, based on a total mass of the oil agent, and a blend ratio of the component B is 5 mass % or more, based on the total mass of the oil agent, said method comprising: metalworking of a difficult-to-machine material with said water-soluble metalworking oil agent, wherein the difficult-to-machine material is at least one selected from the group consisting of titanium and a titanium alloy.
