Water-soluble metal processing oil composition, method for producing water-soluble metal processing oil composition, metal processing liquid and metal processing method

摘要

PROBLEM TO BE SOLVED: To provide a water-soluble metalworking oil composition having excellent grindability on stainless steel, a method for producing the water-soluble metalworking oil composition, a metalworking liquid obtained by diluting the water-soluble metalworking oil composition with water, and these. To provide a metal processing method using. SOLUTION: The oily agent containing (A) a polymerized fatty acid, (B) a sulfur-based extreme pressure agent, and water are contained, and the content (b) of the (B) sulfur-based extreme pressure agent is based on mass. The water-soluble metalworking oil composition having the content (a) or more of the oil-based agent (A). [Selection diagram] Fig. 1
