Mesh CBN

Mesh cubic boron nitride (cBN) provides exceptional thermal conductivity and is used for precision grinding, cutting, and shaping of various ferrous tools

Mesh cubic boron nitride (cBN) is a superabrasive material with a crystal structure similar to synthetic diamond, providing superior wear and oxidation resistance to ferrous materials. It is used in grinding and finishing applications of ferrous materials where high precision and fine surface finishes are required, especially for hard materials such as hardened steels, superalloys, and ceramics.

The morphology and shape of cBN particles play a critical role in the free cutting ability and life of the tool. Our range of cBN products incorporates a variety of shapes each tailored to suit a particular application and bond system.

Our mesh cBN products are available in ANSI particle (grit) sizes from 20/30 to 325/400.

Mesh cBN Applications


With its ability to not chemically wear in the presence of graphite or carbide during the abrasive process, mesh cBN is explicitly designed for applications involving ferrous materials. Mesh cBN is mainly used in grinding ferrous materials like cast iron, wrought iron, steel, nickel alloys, and stainless steel.

Mesh cBN is often used in the production of cutting tools, dies, knives, saw blades, bearing rings, compressor parts, engine components, turbine parts, gears, and various other metal tools.

Frequently Asked Questions about Mesh CBN

What is mesh cBN?

Mesh cBN refers to crystalline cubic boron nitride, a superabrasives material. It is formed by the use of high temperature (1,500 to 2,000°C) and high pressure (3.5 to 6.2 MPa).

How is mesh cBN different from industrial diamond?

Mesh cBN is different from industrial diamonds because it is made of boron and nitrogen and is synthesized to be tailored to provide the required characteristics to grind and finish ferrous tools. Industrial diamonds are superabrasives made of pure carbon and are used to grind and finish nonferrous tools. Mesh cBN also has a thermal stability higher than that of industrial diamond, which means it can withstand higher temperatures without breaking down or losing its cutting ability.

Why does cBN have a color different from that of diamond?

The color of cBN is different from that of industrial diamonds because of its chemical composition. CBN contains boron and nitrogen, which give it a distinct light brown or amber color. Variances in cBN color manifests itself in performance depending on the tool type and application. For example, a boron-rich material is often considered more challenging to see in electroplated tools since it can lead to over-plating.

Why is cBN coated?

CBN is sometimes coated with a thin layer of material, such as titanium, nickel, or copper, to improve its performance in certain industrial applications. Crystal coatings and surface treatments of cBN enhance crystal retention, improve bonding, increase durability, reduce friction, and in some cases provides lubrication characteristics.

What materials are cBN used on?

CBN is used for tools designed to work on ferrous workpiece materials such as hardened steel, bearing steel, nickel-based alloys, and superalloys.

CBN can be used in grinding wheel bond systems using vitrified bonds for machine shops to produce engine components such as cam and crankshafts for the automotive industry.

Specially cleaned and shaped cBN grades are used to produce grinding wheel bond systems of single layers (electroplated) for precision grinding turbine components, such as vanes, blades, and nozzles, and for seals for the aerospace industry.

Titanium-coated cBN is used in metal and hybrid bond systems to produce tools for profile grinding. Nickel-coated cBN is used in resin bond systems to produce precision components in machine tools and die and mold industries.
