This paper deals with a fabrication method for a grinding wheel by electrical discharge machining (EDM) and its evaluation through practical grinding. When the total life of the grinding wheel has ended, the grinding wheel is thrown away although its core is still usable. Depositing an abrasive layer by EDM with a green compact electrode is proposed to fabricate a recyclable grinding wheel for cost reduction. Some metallic disks were practically ground with a #400 SiC abrasive layer. The grinding ratio against steel was 6.9. Then the deposit process for a cylinder was proposed to fabricate and recycle a mounted wheel. The maximum difference for a thickness of 300μm was 10μm by the shape feedback machining method. Although the additional layer was deposited without any cleaning in the recycle process, it performed as well as a new one. Therefore, the abrasive layer fabricated by EDM can be used for grinding.

In the previous paper, we proposed a new method of coloring titanium alloy by electrical discharge machining (EDM) in dielectric water. It was confirmed that coloring by EDM is caused by an interference phenomenon in the anodic oxide film generated on the EDMed surface. In order to apply this new coloring method to titanium products, it is necessary to evaluate the properties of the colored surface. In this study, the corrosion resistance, the weatherability and the wear resistance of the colored surface were discussed. As a result, it was confirmed that the surface colored due to the presence of an oxide layer has high corrosion resistance and excellent weatherability. Moreover, the wear resistance of the colored surface was improved as an additional effect of EDM.
