Claims21
A fluid for cutting and abrasively treating a metal, cermet, or composite workpiece, said fluid comprising:
- a) one or more hydrofluoroether(s) according to the formula:
- (R1—O)n—R2
- wherein:
- n is a number from 1 to 3 inclusive;
- R1 and R2 are the same or are different from one another and are selected from the group consisting of alkyl, aryl, and alkylaryl groups;
- at least one of R1 and R2 contains at least one fluorine atom;
- and
- at least one of R1 and R2 contains at least one hydrogen atom;
- and
- b) one or more additive(s) to impart lubricious properties to said fluid;
- wherein said workpiece has a bulk temperature of less than about 80° C. and wherein said fluid leaves a residue on said workpiece.
A method of cutting or abrasively treating a metal, cermet, or composite workpiece comprising:
- a) applying to said workpiece a fluid comprising:
- (i) one or more hydrofluoroether(s), and
- (ii) one or more additive(s) to impart lubricious properties to said fluid;
- and
- b) cutting or abrasively treating said workpiece;
- wherein said workpiece has a bulk temperature less than about 80° C. and wherein said fluid leaves a residue on said workpiece.
