摘      要：In this research,the advantages and disadvantages of the cylindrical grinding process of Polycrystalline Diamond Compacts(short for PDC) with vitrified and resin bond diamond grinding wheel are *** research results show that the vitrified bond diamond grinding wheels,which use Ti-coated diamond grains as abrasive and glass ceramic as bond,have many advantages in grinding *** with resin diamond grinding wheel,vitrified bond wheels lead to 35% grinding cost reduced,40% grinding time of each PDC saved,and the size precision of PDC improved(from ±0.03mm to ±0.01mm).When grinding feed is 0.10 mm,the grinding ratio increases with increased grinding ***,when the grinding feed exceeds 0.10 mm,the grinding radio decreases rapidly with the increasing of grinding *** disadvantage of this kind of grinding wheel is that the brightness of the ground PDC cylinder is not as shining as that processed by resin bond diamond grinding wheel.
