Development of eco-friendly ELID grinding wheel using plant carbon

Abstract

We are engaged in the development of eco-friendly ELID grinding technology, and have manufactured a conductive carbon bonded diamond wheel for ELID grinding using plant carbon. A nonconducting layer was formed on the carbon wheel surface by electrolytic dressing. The layer has a high friction coefficient, and the layer on a reed carbon wheel has high wear resistance compared with that on a water hyacinth carbon wheel. A plant carbon resin bonded diamond wheel using #1200 abrasive grain was manufactured for the grinding experiment. In the grinding experiment with single-crystal silicon, the surface roughness was set to Ra: 5.2 nm for the combination of plant carbon wheel and ELID grinding.
