cBN exhibits a high abrasion resistance and thermal conductivity when compared to conventional abrasives such as Silicon Carbide and Aluminum Oxide.
The thermal integrity of cBN and its ability to maintain sharp cutting edges when machining ferrous materials make it the product of choice in advanced grinding systems.

cBN-AE4
High Friability
- Resin Bond
- Vitrified Bond
Semi Angular Shape
Density 3.48 g/cm3
Golden amber in color, with a combination of angular and semi-blocky particles. The CBN-AE4 tendency to macro-fracture under impact, along with free cutting characteristics, enhance wheel life and surface finish.
cBN-AMH
High Friability
- Resin Bond
- Vitrified Bond
- Metal Bond
Angular Shape
Density 3.48 g/cm3
Dark to light brown color in equal ratio, high friability, mostly irregular with some angular shaped particles. The AMH tends to macrofracture under impact loading, which coupled with its high thermal stability provides longer wheel life. Recommended for vitrified applications where more compressive residual stresses and high material removal rates are the goal.
cBN-BMA
Medium Friability
- Resin Bond
- Vitrified Bond
Angular Shape
Density 3.48 g/cm3
Black, medium strength, with an angular morphology and high thermal stability. The BMA’s angular morphology produces a free cutting action that reduces heat generation and power consumption while increasing grinding efficiency.
cBN-BMI
Low Friability
- Resin Bond
- Vitrified Bond
- Single Layer Bond
Blocky Shape
Density 3.48 g/cm3
Black, medium strength, with a blocky morphology and high thermal stability. The BMI’s blocky morphology provides a more controlled crystal micro-fracture, allowing the tool to better maintain its form while generating smaller particles under impact.
cBN-BMO
High Friability
- Resin Bond
- Vitrified Bond
- Single Layer Bond
Semi Blocky Shape
Density 3.48 g/cm3
Black, friable, with an irregular shaped morphology. The BMO’s semi blocky morphology produces controlled micro fracturing particles along with free cutting characteristics to enhance wheel life and surface finish.
cBN-BMS
Very Low Friability
- Resin Bond
- Metal Bond
Angular Shape
Density 3.48 g/cm3
Dark gray in color with equal parts of angular and semi blocky shaped particles. The BMS is WWSA’s highest strength micro-crystalline CBN. Optimal for demanding removal rate applications while providing very good surface finish. Recommended for a variety of honing applications.
cBN-BWW
High Friability
- Resin Bond
- Vitrified Bond
Angular Shape
Density 3.48 g/cm3
Black, low strength, with angular shaped particles and medium thermal stability. The BWW’s angular morphology produces a free cutting action that reduces heat generation and power consumption while increasing grinding efficiency.
Resin Bond
systems are widely used for all-purpose superabrasive grinding applications in either phenolic or polyimide bonds. Resin bond systems can be utilized in either wet or dry grinding operations and offer excellent particle retention and part finish.
Vitrified Bond
systems are manufactured from ceramic materials that are strong, durable and brittle. Vitrified bonds are very effective in advanced grinding operations because of their ability to hold the abrasive and reduce heat generation in the grinding zone due to their high porosity levels when compared to other bond types.
Single Layer Bond
systems (electroplated and brazed) hold a single layer of superabrasive grains bonded to a precision machined form. Electroplated systems are bonded with a Nickel matrix and leave approximately 50% of the abrasive exposed while brazed systems leave approximately 80% of the abrasive exposed. Single layer bond systems typically do not require dressing.
