WATER-SOLUBLE METAL WORKING FLUID COMPOSITION, METAL GRINDING METHOD AND GRINDING WORKPIECE

WIPO Patent Application WO/2014/084171

A1

The present invention provides: a water-soluble metal working fluid composition which sufficiently suppresses clogging of a grinding stone during a metal grinding process as well as corrosion of a metal workpiece surface after grinding; and a metal grinding method. The present invention relates to metal working fluid composition which comprises (A) (a1) a water-soluble organic carboxylic acid with a mean molecular weight of 100 or more and less than 5,000 and/or (a2) a water-soluble polymer compound with a weight average molecular weight of 5,000 to 60,000 having an anionic functional group and (B) sulfuric acid ester salt and sulfonate with a mean molecular weight of 150 or more and less than 5,000, the content of component (A) being 25 to 90 weight%, the content of component (a1) being 80 weight% or less and the content of component (a2) being 55 weight% or less with respect to the total content of components (A) and (B). The present invention also relates to a metal grinding method which performs grinding to a metal workpiece with a grinding stone by using the water-soluble metal working fluid composition.
