Abstract
We are studying ways of recycling grinding fluid, supplying grinding fluid and electrode technology in the aim to develop Eco-friendly ELID grinding technology. As one elemental technology of this Eco-friendly ELID grinding technology, we developed a metal free electrode-conductive resinoid bonded wheel using RB ceramics as the conductive material. The prototyped grinding wheel was a #8000 RB ceramics bonded grinding wheel using diamond abrasives. Using this wheel, electrolytic dressing characteristics and grinding characteristics were investigated. Experimental results show that a non-conductive coating is formed on the wheel surface by electrolytic dressing, and this coating has greater frictional coefficient and wear amount than the bonding matrix. Grinding experiments of some hard and brittle materials were carried out using this grinding wheel, and it was found that a stable mirror surface finishing can be realized by adding ELID grinding.
