METALWORKING FLUID COMPOSITION AND METALWORKING PROCESS

摘要

Disclosed is a water-soluble metalworking fluid composition which exhibits excellent decay resistance and hardly has adverse effects on the global environment or the human body. Also disclosed is a metalworking process using such a metalworking fluid composition. Specifically disclosed is a metalworking fluid composition containing an amine having a straight chain or branched alkyl group having 4 or more carbon atoms (component A) and an amine having a cyclo ring or a benzene ring (component B). This metalworking fluid composition is characterized by containing 0.5-20% of the component A and 0.5-20% of the component B. Also specifically disclosed is a metalworking process using such a metalworking fluid composition.
