WIPO Patent Application WO/2005/095556

Kind Code:

A1

Abstract:

A first metalworking fluid of the present invention is characterized by containing an ester oil and a hydrocarbon oil having a kinematic viscosity of 1-20 mm²/s at 40&ring C. A second metalworking fluid of the present invention is characterized in that it contains an ester oil as the base oil and has a moisture content of 200-20,000 ppm. The first and second metalworking fluids are excellent in characteristics of a water-insoluble oil solution for nonferrous metalworking and also excellent in characteristics of an oil solution for cutting/grinding wherein a very slight amount of the oil solution is supplied. These metalworking fluids enable to improve the processing efficiency, and also enable to make life of a processing tool longer.
