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.

  • Single Layer Bond
cBN-BMI

cBN-BMI

Low Friability

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 fracture, allowing the tool to better maintain its form while generating smaller particles under impact.

cBN-AMX

cBN-AMX

Very Low Friability

Blocky Shape
Density 3.48 g/cm3

The AMX is a new high strength CBN grit, its blocky shape with sharp edges maintain both its strength and shape across the tool life at the most demanding ferrous metal grinding operations; useful in high speed grinding applications carried out with electroplated CBN wheels.

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.

Metal Bond

systems are the toughest formed bonds available and are recommended for wet grinding. Metal bonds exhibit high abrasive and heat resistance along with excellent form holding capabilities leading to extended tool life.

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.
