Abstract
An emulsifiable oil composition for machining graphite containing metals comprises a major amount of an oil of lubricating viscosity; at least one surfactant in an amount sufficient to render the oil emulsifiable in water; and, from about 0.8 vol % to about 3 vol % based on the total volume of the composition of an aliphatic alcohol having from 1 to about 8 carbon atoms.

An emulsifiable oil composition for machining graphite containing metals comprising:
- a major amount of a base oil consisting of a paraffinic oil of lubricating viscosity;
- at least one surfactant selected from the group consisting of sulfonates, naphthenates and fatty acids in an amount sufficient to render the oil emulsifiable in water;
- and,
- from about 0.8 vol % to about 3 vol % based on the total volume of the composition of an aliphatic alcohol having from 1 to about 8 carbon atoms.
In the machining of cast iron and graphite containing metals wherein an oil-in-water emulsion is used as coolant, the improvement wherein the oil comprises:
- a major amount of a base oil consisting of a paraffinic oil of lubricating viscosity;
- at least one surfactant selected from the group consisting of sulfonates, naphthenates and fatty, acids in an amount sufficient to render the oil emulsifiable in water;
- and,
- from about 0.8 vol % to about 3 vol % based on the total volume of the composition of an aliphatic alcohol having from 1 to about 8 carbon atoms.
