A lubricant oil composition for warm pressing is provided not to require a degreasing process after pressing a surface of metal and to be an environment-friendly. The lubricant oil composition for warm pressing comprises 1 to 3 wt.% of a hydrocarbon composition of one or more aliphatic hydrocarbon and cyclic aliphatic hydrocarbon; 1 to 3 wt.% of propylene glycol; and 94 to 98 wt.% of polyoxyalkylene glycol monoalkyl ether. The aliphatic hydrocarbon is composed of 40 to 50 wt.% of naphthenic hydrocarbon, 30 to 40 wt.% of iso-paraffinic hydrocarbon, 5 to 15 wt.% of normal-paraffinic hydrocarbon and 5 to 15 wt.% of other aliphatic hydrocarbon.
