Title: METALWORKING OIL COMPOSITION AND METALWORKING METHOD
Abstract:
Provided are: a metalworking oil composition having excellent workability and rust prevention properties, which is obtained by blending (A) at least one carboxylic acid ester selected from among polyhydric alcohol esters of monovalent carboxylic acids and monohydric alcohol esters of polyvalent carboxylic acids, (B) a phosphorus-containing compound and (C) a rust inhibitor, and wherein the number of carbon atoms in each of the monovalent carboxylic acids is from 9 to 21 (inclusive) and the content of the carboxylic acid ester based on the total amount of the composition is 0.6% by mass or more; and a metalworking method which uses this metalworking oil composition.
