Beschreibung
Zusammenfassung:	A metal-working oil composition comprises as essential components thereof (a) one or more lube-oil components selected from the group consisting of oils, fats, mineral oils and fatty acid esters; and (b) one or more water-soluble polymer compounds selected from the group consisting of homopolymers of acrylic amide, copolymers of acrylic amide and other monomers and salts of the homopolymers and copolymers, the molecular weights of which homopolymers, copolymers and salts fall within the range of from 1,000 to 10,000,000. The incorporation of the specific water-soluble compound allows a lube-oil component to disperse stably as large droplets in water and hence, several advantages including thick and strong lubricating film suitable for use under severe machining conditions can be obtained.
