Abstract: The advantages of grinding polycrystalline diamond compacts (PCD) by vitrified bonded and resin bonded diamond grinding wheels are compared. The research shows that the vitrified bonded diamond grinding wheel, which uses titanium plated diamond grains and a glass ceramic bond reduces grinding costs by 35%, grinding duration by 40% and improves precision of size of the PCD compact from ± 30 µm to ± 10 µm. However, when grinding feed exceeds 100 µm; the grinding ratio decreases rapidly.
