Feathers: 
1. High grinding efficiency than that of metal bonded diamond grinding wheel 
2. High abrasion resistance and less abrasive consumption 
3.Small grinding force and low grinding temperature 
4.High grinding precision of the work piece, good surface quality and good maintenance of the shape of workpiece 

Application: 
They are widely used in the fields of tungsten carbide, ceramics, glsasses, PCD, PCBN, CVD, natural diamond, stones, etc. 

Advantage: 
1.high quality of PCD & PCBN insert edges after sharpening; 
2.short grinding time&long tool life 
3.high efficiency and accuracy of sharpening; 
4.remarkable decreasing of unitary grinding costs
