Abstract: A metal-working oil composition containing the following three components (A), (B) and (C) as its essential components: (A) one or more lube-oil components selected from the group consisting of oils, fats, mineral oils and fatty acid esters; (B) a cationic or amphoteric water-soluble polymer compound having a molecular weight of 1,000 to 10,000,000, containing nitrogen atoms in its molecule; and (C) a surfactant. A metal-working oil composition according to the invention can further and optionally comprise an extreme-pressure additive, which can enhance the lubrication performance. When the metal-working oil composition is brought into contact with a metallic workpiece, oil droplets having a uniform diameter form a thick and strong lubricating film over the workpiece, thus the composition can be successfully employed for processing metals under high shear, high-speed and high-pressure conditions.
