Claims8
A method for machining of fiber-reinforced composite materials comprising the step of applying to a fiber-reinforced composite material a coolant, wherein the coolant comprises one or more components selected from the group consisting of an oil component, an amino alcohol (alkanolamine), a corrosion inhibitor, an emulsifier, a defoamer and a biocide, and each of the following:
- (a) a sulfurized hydrocarbon with 4 to 30 carbon atoms and 1 to 5 sulfur atoms and/or a sulfurized triglyceride with 10 to 20 carbon atoms in the fatty acid residue,
- (b) an ethoxylated and/or propoxylated alkyl phosphate with 12 to 30 carbon atoms in the alkyl radical,
- (c) a phosphoric acid ester with fatty alcohol polyglycol ether,
- (d) a maleic acid dibutyl ester, polymerized with C10-20-1-alkenes, and
- (e) an epoxidized ester.
