The material of superabrasive include two materials—Diamond and CBN.
The Diamond/CBN honing stone are munufactured with high quality
abrasive and metal powder from home and abroad, strictly abiding by
ISO9001 quality management system. Advanced manufacture technology
and formula system not only ensure high precision honing quality and
production efficiency, but also effectively extend the service life of honing
stone.
With the characteristics of high strength and hardness, suitable for
all non-carbide hard materials, Diamond honing stone can be widely
used to hone glass, quartz, rigid alloy, cast iron, ceramic materials etc.
While with the characteristics of high strength and hardness, suitable for
all hard materials, CBN honing stone can be used to hone types of steel
and alloys.
KBD products of honing stone can be equipped to most
of home and abroad honing machines. For example, Amarica SUNNEN,
Germany GEHRING, NAGEL, Japan FUJI, CHISHIMA, TOYO, NISSIN,
ect. Our Products are also as good as those products from America, Germany
and Japan
.

The material of superabrasive include two materials—Diamond and CBN. Compared with the common grinding wheel, superabrasive grinding wheel has more superior performance in all respects—high strength, long life, sharp cutting, high grinding efficiency, good shape retention and high accuracy control, ect.
As we all know, different wheels should be used in different workpiece materials and processing requirements.
Diamond wheel, which is the most widely used, is the best abrasive tools for grinding carbide, optical glass, ceramics, gems and stone, high hardness brittle non-metallic materials.
CBN (Cubic Boron Nitride) wheel is the best abrasive tools for grinding hardened steel, high-speed tool steel, bearing steel, stainless steel, heat resistant steel, titanium alloys and high hardness toughness of metal materials.
