In this study, we experimentally built a metal-free electro-conductive resin bonded wheel made of carbon as the conductive material to reduce metal ions in grinding fluid and reduction of pollution on the workpiece by metal in the aim to develop LED grinding techniques that are environmentally friendly. At the same time, we also investigated the characteristics of initial electrolytic-dressing characteristics and grinding characteristics. The results showed that the prototyped metal-free electro-conductive resin bonded wheel consisted of a layer of oxides with high oxygen level formed on the wheel surface by the electrolytic dressing. This wheel was also found to have good surface roughness compared to the cast iron bonded wheel generally used for ELID grinding.
