ABSTRACT:
The present invention relates to a cooling fluid for metal cutting, drilling, grinding and other fabricating operations comprising a compound of the formula C.sub.6 H.sub.4 (OH)COOR, where R is selected from the group consisting of --H,--CH.sub.3, --C.sub.2 H.sub.5,--C.sub.3 H.sub.7, and --C.sub.4 H.sub.9, a ketone with a boiling point of at least about 150.degree. F., and an at least partially soluble acid.
The present invention also relates to a process and fluid product made by a certain process for cooling tools and workpieces for metal cutting, drilling, grinding and other fabricating operations comprising the steps of mixing a compound of the formula C.sub.6 H.sub.4 (OH)COOR, where R is selected from the group consisting of --H,--CH.sub.3,--C.sub.2 H.sub.5,--C.sub.3 H.sub.7, and --C.sub.4 H.sub.9, a ketone with a boiling point of at least about 150.degree. F., and an at least partially soluble acid, the mixture being a cooling fluid, maintaining substantial contact between the cooling fluid and an amount of transition metal or alloy containing at least one transition metal, sufficient to catalyze a reaction within the fluids during fabrication, and operating a tool while maintaining substantial contact between the tool and the fluid during fabrication.
