Document Type and Number:
WIPO Patent Application WO/2013/147136
Kind Code:
A1
Abstract:
Provided is a lubricating oil composition for metalworking that can simultaneously offer high load resistance performance and exceptional cleaning properties without requiring a chlorine-based oil to be used, and can be used under severe lubricating conditions such as steel pipe expansion processing by using a lubricating oil composition containing (a) a base oil, (b) a metal sulfonate, (c) an active polysulfide, (d) a fatty acid partial ester of a polyhydric alcohol, and (e) a non-ionic surfactant; and having a kinematic viscosity at 40°C of 50 to 1000 mm2/s.
