Metalworking fluid composition, and processing method using the same, machined parts

摘要

PROBLEM TO BE SOLVED: To provide a metalworking oil composition having excellent putrefaction resistance, low skin irritation, excellent defoaming property, stability and lubricity (machinability, grindability).;SOLUTION: A metalworking oil composition contains (A) at least one kinds of a primary, secondary, or tertiary alkanolamine, (b) at least one kinds of branched saturated fatty acid having 8 to 40 carbone atoms, (C) a saturated or unsaturated linear fatty acid having 8 to 30 carbone atoms. The alkanolamine of component (A) contains at least one kinds selected from a group consisting of (A-1) amino butanol, amino pentanol, amino hexanol, amino octanol and amino dodecanol and percentage of (A-1) is 5 to 35 mass% on the basis of the total mass of the amine included in the composition.;COPYRIGHT: (C)2014,JPO&INPIT
