Development and Application of CSD Diamond Abrasives

Abstract:

. Traditional diamond grits used for making resin bonded abrasives are monocrystalline in acicular shape and with smooth surface, so they are easy to fall off prematurely during grinding, the use effect is not good. Taking the powder graphite and the iron-base alloy catalyst as the raw material by adopting a new indirect heating craft, under the high pressure and high temperature conditions within cubic press, this project developed a new variety of diamond -- CSD abrasive with crumb structure. They have equi-axed shape and rough surface. It has been proved that the abrasive wheels made with CSD diamond have self-sharpening characteristics and high bondability. The grinding efficiency and service life of the abrasive wheels made with CSD can be doubled.
