SYNTHETIC DIAMOND GRINDING POWDERS

 

AC4  is characterized by an increased friability, its grains being represented by aggregates and concretions.
Best for producing the resin bond diamond tools  used for grinding and finishing of hard alloys.

AC6 - the grains are mainly represented by non-ideal crystals, their fractions or concretions.
Best for producing the resin, metal and ceramic bond tools used for grinding hard alloys, ceramics, glass and other friable materials.

AC15, AC20 - these are represented by crystal fractions and their concretions of an elongated shape with a developed surface.
Best for producing the metal bond tools used for grinding, drilling and cutting of glass, quartz, sapphire and for hard alloys processing.

AC32 - the grains are represented by crystals and their fractions.
Best for producing the metal bond tools used for stone grinding, soft rock cutting and for processing glass, ruby, leuco sapphire, corundum and for rough honing.

AC50 - whole crystals and their fractions noted for their high strength.
Best for producing the metal bond tools used for stone grinding, soft rock cutting and for processing glass, ruby, leuco sapphire, corundum and for rough honing.
