Series Brief

GRD series diamond consists of single crystal diamond and polycrystalline diamond. GRD10 and GRD20 are single crystals with polygonal shapes, blocks and flakes. They have good sharpness. They are suitable for bonds such as resin and ceramics.

GRD40 and GRD60 are polycrystalline diamonds, which are irregular shape and composed of many fine grains. Due to their unique shape and micro crushing properties, GRD polycrystalline abrasives have very good self-sharpness and can greatly improve grinding efficiency, thereby reduce energy consumption and save the cost.

Grades Desription 

GRD10 series consists of crystal in needle and angular shape. Its irregular shape enables great sharpness. They are recommended to grind materials that demand large removal rate and less grinding impact, like tungsten carbide, functional ceramics, etc.

GRD20 series diamonds consists of angular crystal, its impact resistance is much limited, it is applicable for low impact and large removal rate. It could be applied in electroplated and vitrified bond tools .

GRD40 series with angular shape, its fracture surface brings excellent sharpness and it is applicable for grinding condition with strict requirement.

GRD60 series with blocky multi-crystal, its toughness is higher than GRD40. Being great both in sharpness and life, it is applicable for condition of heavy load.

Coating Brief

GRD abrasives exhibit better performance in different binders after different coatings.

Generally, the wettability of the diamond can be improved, so that the holding force between the diamond and the binder is stronger.

At the same time, it can greatly improve the heat dissipation performance of the tool and reduce the surface burn for the workpiece.
