Abstract
Disclosed are a metal processing lubricating oil composition and a process for producing the same. A metal processing lubricating oil composition according to this invention comprises mineral oil, synthetic oil or a mixture thereof, and phosphoric ester and orthophosphoric acid mixed and heated in the mineral oil, synthetic oil or mixture thereof. The lubricating oil composition gets rid of the tiresome pre-treatment associated with the conventional lubricating method, and exhibits a high seizure prevention performance in cold plastic working only by coating it on workpieces. The lubricating oil composition may further comprise metallic phosphate to suppress corrosivity against ferrous materials.
