Realization of eco-friendly electrochemical micromachining using mineral water as an electrolyte

This paper presents a new electrochemical micromachining method, which uses everyday mineral water as an electrolyte. The advantages of the new method include totally green machining, high precision, high efficiency, and low-cost. In this paper, practical experiments and results that focus on the fabrication of micro pins and micro hole drilling as well as a more detailed theoretical analysis to explain the phenomena concerned are presented.
