PROBLEM TO BE SOLVED: To obtain an oil composition useful for metal plastic working such as calendering, drawing or squeezing, containing each specific polyhydric alcohol alkylene oxide adduct(s) and oxygen-contg. compound(s) such as polyalkylene glycol(s). SOLUTION: This metal processing oil composition contains (A) 0.1-10wt.% of at least one kind of oxygen-contg. compound selected from (i) 3-6 hydroxyl- bearing polyhydric alcohol alkylene oxide adducts each having 200-1,000 number- average molecular weight and (ii) 3-6 hydroxyl-bearing polyhydric alcohol alkylene oxide hydrocarbyl ethers each having 200-1,000 number-average molecular weight and (B) 0.1-10wt.% of at least one kind of oxygen-contg. compound selected from (iii) polyalkylene glycols each having 150-1,000 number-average molecular weight, (iv) polyalkylene glycol hydrocarbyl ethers each having 150-1,000 number-average molecular weight and (v) 2-8C dihydric alcohols. |
