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 compared.The 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 PDC.Compared 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 feed.However,when the grinding feed exceeds 0.10 mm,the grinding radio decreases rapidly with the increasing of grinding feed.The 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.

The 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 PDC . Compared 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 feed. However, when the grinding feed exceeds 0. 10 mm, the grinding radio decreases rapidly with the increasing of grinding feed. The 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.
