Overview of Solid PCBN CBN inserts Turning tools CNMN RNMN DNMN TNMN WNMN SNMN Cubic Boron Nitride
Boron Carbide (B4C) is a ceramic compound renowned for its exceptional hardness and wear resistance, ranking just below diamond and cubic boron nitride in terms of hardness. Composed of boron and carbon atoms arranged in a covalently bonded crystal structure, it exhibits unique physical and chemical properties that make it highly valuable in various industrial and military applications. Boron carbide’s high melting point, low density, neutron-absorbing capability, and extreme toughness further distinguish it among advanced materials.
Features of Solid PCBN CBN inserts Turning tools CNMN RNMN DNMN TNMN WNMN SNMN Cubic Boron Nitride
-
Extreme Hardness: With a Mohs hardness of around 9.3 to 9.5, boron carbide is one of the hardest materials known, surpassed only by diamond and cubic boron nitride.
-
Lightweight: Despite its hardness, boron carbide has a relatively low density of about 2.52 g/cm³, which makes it an attractive material for lightweight armor systems.
-
Thermal Stability: It possesses excellent thermal stability, maintaining its properties up to temperatures around 2,000°C, making it suitable for high-temperature applications.
-
Neutron Absorption: Boron carbide is a potent neutron absorber due to its boron content, making it ideal for nuclear shielding and control rods.
-
Chemical Resistance: Resistant to most acids and alkalis, except for hydrofluoric acid and hot concentrated alkaline solutions, ensuring durability in corrosive environments.
-
Abrasion Resistance: Its exceptional wear resistance makes it suitable for applications where friction and abrasion are prevalent, such as sandblasting nozzles.

Parameters of Solid PCBN CBN inserts Turning tools CNMN RNMN DNMN TNMN WNMN SNMN Cubic Boron Nitride
The SolidPCBN/CBN inserts you mentioned are commonly used in cutting tools and machinery, especially for automotive industry. They consist of solid carbide carbons that have been coated with a polymer film, which is called “solidPCBN” or “CBN”. The polymer films help to improve the tool’s hardness, wear resistance, and surface finish.
The “CNMN,” “RNMN,” “DNMN,” “TNMN,” “WNMN,” and “SNMN” refer to different grades of SolidPCBN/CBN inserts. Each grade has its own unique properties and characteristics:
– CNMN: This is the highest grade of SolidPCBN/CBN insert, offering the best wear resistance and durability.
– RNMN: This grade offers a good balance between wear resistance and cost-effectiveness.
– DNMN: This is the middle-grade of SolidPCBN/CBN inserts, providing moderate wear resistance at an affordable price.
– TNMN: This grade offers a moderate balance between wear resistance and cost-effectiveness.
– WNMN: This grade offers medium wear resistance at an affordable price.
– SNMN: This grade offers low wear resistance at an affordable price.
The SolidPCBN/CBN inserts can also be customized by adding different layers of polymer films or by changing their composition. These inserts are widely used in a variety of applications such as die cutting, lapping, drilling, and cutting of metal parts.
In terms of parameters, they include hardness (H), wear resistance (HR), porosity (P), void fraction (Vf), and number of defects (ND). Hardness measures how hard the carbide layer on the is; HR measures how well the carbide layer withstands wear and tear. Porosity measures how many defects there are in the layer; Vf measures how much porosity it has; and ND measures the number of defects present in the layer.
It is important to note that these values may vary depending on the specific application and the manufacturer. It is recommended to consult the manufacturer’s specifications or seek advice from a professional if you need more information about the parameters of SolidPCBN/CBN inserts.
