Abstract
A special coolant system, named ‘Ion-shot coolant system’, was developed. The system uses an electrolyzed ELID coolant containing nano carbon particles. The products of the electrolysis of the ELID coolant and the added carbon particles in the coolant were effective on cutting of ferrous materials by diamond tools. A series of experimental studies has been conducted to understand the effects of the electrolyzed ELID coolant containing nano carbon additives. The coolants containing products of the cathode and anode were compared for micro cutting. The proposed method is expected to expand the use of diamond tools for ferrous materials aiming ultra precision machining of dies and molds with environment-friendly method.
