Diamond abrasives are commonly classed as superabrasives due to their extreme toughness when compared with other abrasive materials.  It is these unique properties that set diamond apart and make it such an important ingredient in advanced grinding operations.With advanced technology it is now possible to grow synthetic diamond crystals in various sizes and qualities giving the tool producer even more choice.  These man made materials have not fully replaced  natural diamond which still has other advantages over the synthetic diamond grits and powders depending on the application.

RVD Resin Bond Diamond

Using RVD diamond as raw materials; appearing sharp-edged of grinding wheels when being crushed under certain pressure, have good self-sharpness performance; Irregular particle surface and shape-edged of corner cut.

MBD Metal Bond Diamond

Regular and nice crystalline form, little impurity, good strength and perfect thermal stability. It also can be used for metal bond tools, electroplated tools, sawing and drilling tools etc.

SMD series
SMD synthetic diamond Manufactured by high pressure and high temperature mean. It has the characteristics of complete crystal shape, good transparency, high impact strength and great thermal stability. It’s mainly used for high grade drilling tools, cutting and grinding tools etc.

In diamond wheels, diamond grit locates in a relatively thin abrasive layer on the perimeter or face of the wheels. Diamond grit is embedded in some bonding material that constructs this layer. Normally, total diamond grit embedded is not more than 26% of the total mass of this layer.

Improper bonding may reduce the effectiveness of the grinding wheel during the operation. If the bond material is not strong enough to retain the diamond, the grits will be pulled away bodily and the workpiece will be rubbed only by the bond. On the other hand, if the bond holds the grit very firmly, the edges and points of the grit will eventually be rubbed flat or broken off, and the wheel becomes ineffective. A steady and continuous grinding process can be maintained only if the wear of the grits is accompanied by some wear of the bond at an appropriate rate. In this case worn grits will fall out and new unworn grits are uncovered to take their place.
