For coarse grinding, the bond should be softer and the diamonds' quality should be higher, because in this case the diamonds are more easily to become blunt. The diamond grit should be bigger, normally from 35 grit to 50 grit. For this is coarse grinding and big grit can improve working efficiency. The diamond concentration can be lower.For fine grinding, the bond should be harder and the diamonds' quality can be lower, for in this case the diamonds can last longer and hard bond can also help the precision of the processing. The diamond grit is normally between 80 grit to 120 grit, depending on the grinding requirements. The diamond concentration should be higher.Outer Diameter Inner Hole Thickness Height 8022.23/M145710022.23/M145712522.23/M145715022.23/M145718022.23/M145723022.23/M1457Our advantages:1.Long life:Accurate shape,high grinding efficiency with long life.2.Rich experience:High working efficiency,used different bonds according to different grinding materials.3.Strong stability:Each product with strict dynamic balancing testing,to make sure the stability during the process.And greatly reduce the maintenance rate of machine.4.More safe:With special produce technology,to make sure the perfect bond between segment and body.It's more safe than traditional technology.Why choosing us:1. Factory with more than 20 years experience in diamond tool industry.2. A great quantity of formula special for all kinds of different stone.3. Approved quality with factory price.4. Long lifespan, good sharpness, stable performance and high cutting efficiency.5. Custom-design can be meet upon request, and small trial order available any time.6. Different market need different quality and sizes. We can make all kinds of sizes and qualityor price according your requirement
