Diamond Grinding Wheel for PCD, PCBN Tools

Application of Diamond Grinding Wheel for PCD, PCBN Tools

PCD and PCBN materials have high hardness and high sharpening. In the process of machining, the grinding efficiency is low, the grinding mechanism is complex and it is difficult to guarantee the quality. Therefore, the Diamond grinding wheel is an ideal grinding tool according to comparison and analysis.

Selection of bond for diamond grinding wheel

Vitrified bond (rough grinding, finish grinding)

The vitrified bond grinding wheel has the advantages of high-temperature resistance, high machining efficiency, good rigidity, good tool shape retention in the grinding process, and high dimensional accuracy of finished products. Vitrified diamond grinding wheel grind PCD, PCBN tools, which can greatly improve grinding efficiency (It is 4 times of that of metal bond), and grinding ratio is low, service life is long (It is about 150 times longer than that of resin wheel.), At the same time, the grinding surface quality of vitrified wheel is good, which is similar to that of metal bond grinding wheel.
Resin bond (finish grinding, super finish grinding)

In super finish grinding PCD. PCBN, resin bond can be selected if the surface finish of the workpiece is highly required. Resin bond grinding wheel has a good advantage in super finish grinding and polishing.

Selection of grit

Rough grinding: W14 W28 W40

Finish grinding: W10

Super finish grinding: W5 W3.5

Other grit will be customized upon request.
