[PROBLEMS] To obtain excellent workability even under severe processing conditions in plastic processing of aluminum or aluminum alloy square products, and to easily remove oil after plastic processing, and to have excellent stability. Providing a lubricating oil composition for processing. SOLUTION: At least one base oil selected from mineral oil and synthetic oil, 5 to 30% by mass of an aliphatic monohydric alcohol having 8 to 24 carbon atoms based on the total amount of the composition, and the following general formula (1) 1 to 30% by mass of a polyoxyalkylene alkyl ether having an HLB value of 9 to 14, and used for plastic working of aluminum or aluminum alloy without being diluted with water, object. R 1 —O— (R 2 —O) n —R 3 (1) [In Formula (1), R 1 is an alkyl group having 1 to 30 carbon atoms or a hydrogen atom, R 2 is an alkylene group having 2 to 4 carbon atoms, R 3 is an alkyl group having 1 to 30 carbon atoms, and n is 2 to 2. An integer of 20 is shown respectively. ] [Selection] Figure 1 |
