Abstract
Metal and resin bonded diamond wheels were trial manufactured from boron doped
diamond grits possessing electrical conductivity and high oxidation temperature. From the results of
the investigation on the electro-discharge truing performance, a high truing efficiency along with
the possibility of formation of cutting edges on the grits was confirmed. According to the results of
the grinding experiment performed using this grinding wheel with flattened abrasive tips, a
remarkable improvement in the work surface roughness could be achieved. Furthermore, from the
results of the grinding test on cemented carbide and optical glass using the boron doped diamond
grits wheel, the grinding ratio was found to increase significantly, whereas the surface roughness
improved compared to a conventional diamond grits (similar friability) wheel.
