WATER-SOLUBLE WORKING OIL FOR FIXED-ABRASIVE WIRE SAW

摘要

A water-soluble working oil for fixed-abrasive wire saws which imparts excellent cutting properties in the cutting of a hard work made of, e.g., glass, sapphire, ceramic, silicon, or neodymium with a fixed-abrasive wire saw. The oil can thus improve cutting efficiency. The oil causes no problem concerning, e.g., bubbling. The water-soluble working oil for fixed-abrasive wire saws is characterized by comprising (A) an alkylene oxide adduct of an organic amine, (B) an aliphatic carboxylic acid, (C) a basic substance, and (D) water. Also provided are: a method of processing a hard work with the oil; and a product of hard-work processing obtained by the hard-work processing method.
