Title:
WATER-SOLUBLE METALWORKING OIL AGENT, METALWORKING FLUID, AND METALWORKING METHOD
Document Type and Number:
WIPO Patent Application WO/2013/073617
Kind Code:
A1
Abstract:
A water-soluble metalworking oil agent including a component (A), a component (B), a component (C), and a component (D). The component (A) is an ester compound having a characteristic temperature measured on the basis of JIS K2242 of at least 570°, and is contained in the amount of at least 10% by mass relative to the total amount of the water-soluble metalworking oil agent. The component (B): is at least one type of condensed fatty acid from either a condensed fatty acid (1) obtained by dehydration and condensation of hydroxy carboxylic acid, or a condensed fatty acid (2) obtained by dehydration and condensation of a monovalent carboxylic acid and an alcoholic hydroxyl group of the condensed fatty acid (1); has a characteristic temperature measured on the basis of JIS K2242 of at least 650°C; and is contained in the amount of at least 7.5% by mass relative to the total amount of the water-soluble metalworking oil agent. The component (C) is a carboxylic acid and is contained in the amount of at least 2% by mass, relative to the total amount of the water-soluble metalworking oil agent. The component (D) is a basic compound and is contained in the amount of at least a neutralization equivalent amount whereby the acid value of the sum of the components (B) and (C) is neutralized. As a result, the agent is capable of exhibiting excellent workability in relation to hard-to-work materials, and tool life can be prolonged.
