LUBRICANT COMPOSITION FOR METAL PROCESSING

摘要

PROBLEM TO BE SOLVED: To provide a non-chlorine-based lubricant composition for metal processing excellent in processing performance and capable of suitably being used as a processing oil applicable under difficult-to-process condition.SOLUTION: There is provided a lubricant composition for metal processing containing a lubricant base oil having kinetic viscosity at 40°C of 2 to 68 mm/s of 60 to 98.5 mass%, [A] dialkyl polysulfide represented by the formula (1) of 1 o 20 mass% and [B] calcium salicylate represented by the formula (2) of 0.5 to 20 mass%. R-Sm-R(1), where Rand Rare C4 to 16 alkyl group and m is the number of 2.5 or more. (2), where Ris each independently a C14 to 28 alkyl group and n is 1 or 2.SELECTED DRAWING: None
