Abstract

Provided is a metal working oil which comprises (A) a base oil comprising 2-ethylhexanol palmitate or stearate and (B) an anionic active agent comprising a salt of a C8-18 branched aliphatic carboxylic acid with a C3-12 branched alkanolamine. The metal working oil has excellent suitability for cutting, less-foaming properties, concentrate stability, emulsion stability, and hydrolytic resistance and has low dynamic viscosity at low temperatures.

Description

technical field [0001] The present invention relates to an oil agent for metal processing that can be widely used in metal processing such as cutting processing, grinding processing, rolling processing, stamping processing, and plastic processing. In more detail, it relates to a metalworking oil used by diluting it with water, especially a metalworking oil excellent in machinability, a metalworking method using the metalworking oil, and a metalworked product produced by the metalworking method . Background technique [0002] Generally, cutting and grinding oils are used in cutting and grinding processes. The most important function of cutting and grinding oils is the lubricating effect, which can improve the life of the tools used in processing, improve the surface accuracy of the workpiece, and improve productivity, etc., and can improve productivity. . In addition, regarding these required performances, studies have also been carried out from the processing method, and ...
