(57) [Abstract] [Problem] Good removal (cleanability) of abrasion powder generated when performing plastic working, cutting work, grinding work, etc. on aluminum, steel, brass and other metals or alloys. The present invention provides a lubricating oil for metalworking which is excellent in workability and can finish the surface condition of the work material satisfactorily. SOLUTION: (A) a base oil mainly composed of a straight-chain olefin having 6 to 40 carbon atoms; (B) a branched saturated or unsaturated aliphatic alcohol having 6 to 40 carbon atoms; 20 or more alcohols selected from 20 linear or saturated aliphatic alcohols and (C) one or more compounds selected from alkylene glycols, alkylene glycol derivatives, polyalkylene glycols and polyalkylene glycol derivatives Is a lubricating oil composition for metalworking comprising |
