~Vitrified Diamond Grinding Wheel for PCD and PCBN Tool
Vitrified bond diamond wheel shares in common characteristics of diamond and vitrified binding agent:
1) Compared with corundum, silicon carbide wheel, its grinding force, grinding temperature is relatively low, grinding wheel wear is relatively small
2) Suitable to the action of various coolants
3)  Maintain good shape when grinding, high precision workpiece
4)  There are more pores in the grinding wheel, it is good for chip removal and heating removal, it is not easy to jam and burn.
 5）Self-sharpening is better, dressing interval for a long time, dressing easier.
So vitrified bond diamond grinding wheels used in developed foreign countries are growing.
Vitrified bond diamond grinding wheel has the following advantages;
1) High grinding efficiency
2) High wear resistance, less abrasive grain consumption , especially obvious when grinding very hard and brittle workpiece
3) Small grinding force, low grinding temperature
4) High precision workpiece, good quality surface, good shape for workpiece

Therefore, vitrified diamond grinding wheel have more and more obvious advantages in some special materials grinding and has a good prospect in the development of diamond grinding wheel. Vitrified diamond grinding wheel is considered to be high speed, high efficiency, high precision, low grinding cost, low environment pollution performance. Vitrified diamond grinding wheel is more widely used , which is a hot spot of research and development in the world recently.

In view of the above, for the grinding PCD tool, since the resin binding agent  is more soft, easy to deformation when grinding, can not effectively grinding PCD tool. Metal binding agent makes grinding wheel poor self-sharpening owing to strong combination of abrasive grains. It has low grinding efficiency, and the metal bond diamond grinding wheel will cause the PCD tool edge serious damage. According to grinding efficiency, durable and workpiece surface processing quality, vitrified bond diamond grinding wheel is ideal choice for PCD tool.

Application：
Vitrified bond diamond grinding wheel is mainly used for grinding PCD, CVD, PCBN, hard carbide, vitrified cutting tools ,milling cutter, drill, reamer and other cutting tools and fast high efficiency and low damage grinding.
Vitrified diamond grinding wheels are also widely used in wafers (semiconductor wafers and solar wafers), diamond composite films, diamond polycrystalline, diamond cutting tools, cubic boron nitride(CBN), tungsten steel (hard carbide), new type of engineering structural ceramics, precious stones, crystal, rare earth materials (magnetic materials) and other high hard and brittle materials, and be achieved good economic benefits.
