When grinding CBN tools, resin bond diamond grinding wheel is mostly used. If the machining tolerance is big, you can use 140/170 for rough grinding,then use230/270,W35,W28 for fine grinding. If you want to save cost & time you can choose W35 for whole grinding.
Application of resin diamond grinding wheel
Especially for face and peripheral grinding of carbide&CBN tools.
Advantages:
1.Precision control of geometric tolerance
2.Good Self-sharpening
3.High Working Efficiency
4.Good Elastic&Good Polishing Performance
5.Superior insert edge quality
