How diamond density affects segment performance?

 

Diamond segment is a metallic product made of diamond grit and metal bond. Metal bond is a mixed metal powder of Fe,Ni, Cu, Mn, Sn, Zn, AI, Co, Cr, W, Ti, Ce, La, Si and B and another important working abrasive is diamond grit. Inside each diamond segment, there is a certain ratio of diamond grit, which decides performance of segments in cutting. If diamond grit takes 25% volume size a segments, we name its diamond density 100%.


Diamond Grit


Diamond density is an important factor in diamond tools, it plays an important roles in tools working efficiency, longevity and performance. If diamond density is high, diamond grit quantity in a working layer space is bigger, force on each grit is smaller, cutting depth onto working pieces is smaller, diamond grit is not easily broken or fallen off but it is also easily get grounded or polished and thus its working efficiency is lower and life is longer. And if diamond density is lower, forces on each diamond grit is bigger, cutting depth onto working pieces is bigger, and diamond grit is more easily broken and fallen off, tool is more likely working more efficient and life shorter.
