PURIFICATION METHOD OF WATER-SOLUBLE METAL PROCESSING OIL SOLUTION

Japanese Patent JP2015124374

A

PROBLEM TO BE SOLVED: To provide a purification method of a water-soluble metal processing oil solution capable of preventing bad odor generation caused by decay by suppressing proliferation of microbe in the water-soluble metal processing oil solution, and further to provide a metal processing method capable of achieving thereby stable operation of a machine tool.SOLUTION: In a purification method of a water-soluble metal processing oil solution, proliferation of microbe is suppressed by allowing a magnesium metal to exist in the water-soluble metal processing oil solution. Metal processing of a workpiece is performed by a machine tool by using a water-soluble metal processing oil in which proliferation of microbe is suppressed by the purification method of the water-soluble metal processing oil solution.
