Development of processing liquids for machining. Preventing the problem of rust

The processing fluids used in conventional cutting and grinding processes contain agents such as oil and surfactants. However, there is concern about the health hazard to workers, and both cost and greenhouse gas emissions are issues in the processing, such as incineration, of the waste liquids. To address this problem, I have developed an electric rust prevention processing method that uses water alone as the working fluid. When processing is carried out with water, rust-related problems may occur, and this has been solved by applying a weak electric current to the workpiece (ferrous material) being processed. In addition, I am also engaged in research into microprocessing using an adhesion process where metal is deposited, instead of a removal process where metal is ground away.
