CBN Diamond Sanding Belts

CBN (cubic boron nitride) is a highly sought-after abrasive grain due to its exceptional hardness and chemical inertness, second only to diamond. Our new CBN abrasives are specially designed to tackle the toughest materials, including hardened steel (>55 HRC), ceramic materials, high-speed steel, nickel-based superalloys, and chilled castings.
One of the key features of our CBN abrasive belts is their flexibility, thanks to the use of patented aramid fibers as a support material. Aramid fibers, also known as Kevlar, are renowned for their high strength, elongation, and vibration-dampening properties. To further enhance the durability and performance of our CBN abrasives, the support material is applied with a formfitting copper layer.
The CBN crystals are then bonded to the abrasive belt using a galvanic process that involves a nickel-based alloy. Depending on the application, the CBN crystals can be arranged in a regular intermittent pattern or with no spacing, covering the entire surface of the belt. This ensures maximum cutting efficiency and a longer service life for the abrasive belt.
Whether you're working with tough materials like hardened steel or looking for a high-performance abrasive solution for your manufacturing process, our CBN abrasives are the perfect choice. With their exceptional hardness, chemical inertness, and flexible design, they offer unparalleled cutting power and durability.

CBN (Cubic Boron Nitride) Abrasive Sanding Belts are advanced abrasive tools designed for precise sanding and grinding applications, especially when working with hard and tough materials. They find extensive use across various industries that require high-precision material removal:

  1. Metalworking: CBN sanding belts are crucial in the metalworking industry for sanding and shaping hardened steel, high-speed steel, and other ferrous materials. They are employed in tasks such as tool and die making, sharpening cutting tools, and precision grinding.

  2. Aerospace: In aerospace manufacturing, CBN belts are used for sanding and grinding critical components like aircraft engine parts, turbine blades, and aerospace alloys due to their ability to maintain tight tolerances and produce superior surface finishes.

  3. Automotive: CBN abrasive sanding belts play a vital role in automotive manufacturing, particularly in the production of engine components, transmission parts, and high-precision gears.

  4. Bearings: They are used in the production of bearings to achieve precise shapes and tolerances, ensuring smooth and efficient bearing operation.

  5. Ceramics and Hard Materials: CBN sanding belts are suitable for sanding ceramics, advanced ceramics, and extremely hard materials that are challenging to process with conventional abrasives.


  1. Cubic Boron Nitride Abrasive: CBN belts are coated with cubic boron nitride, an exceptionally hard material that rivals diamond in hardness. This characteristic makes them ideal for sanding hard materials.

  2. High Thermal Conductivity: CBN exhibits high thermal conductivity, which helps dissipate heat generated during sanding, reducing the risk of overheating and thermal damage to the workpiece.

  3. Precision Sanding: CBN abrasive sanding belts excel in precision sanding applications, delivering consistent results and maintaining tight tolerances.

  4. Longevity: CBN abrasive is highly durable, ensuring an extended belt life and reduced tool wear, resulting in cost savings.


CBN Abrasive Sanding Belts offer outstanding performance in various aspects:

  • Efficient Material Removal: They remove material efficiently, especially from hard and difficult-to-machine materials, resulting in reduced sanding time.

  • High Surface Finish: CBN belts produce superior surface finishes, reducing the need for additional finishing processes.

  • Dimensional Accuracy: These belts maintain precise dimensions and tolerances, ensuring the workpiece meets strict quality standards.

  • Reduced Heat Generation: CBN's high thermal conductivity minimizes heat buildup during sanding, preventing thermal damage to the workpiece.

  • Longevity: CBN abrasive sanding belts have a long lifespan, reducing the frequency of belt replacements and associated downtime.

  • Versatility: They are versatile tools suitable for a wide range of materials and applications, making them a valuable asset in industries that require high-precision sanding and grinding.

Frequenstly Answer Qeustion

Q: What are the situations where diamonds are used as cutting tool?

Diamond excels in "hardness" and "heat diffusibility" as a cutting tool material. CBN, with hardness akin to that of diamond diamond is mainly used for cutting ferrous metal thanks to its lower reactivity than diamond with ferrous metal. Both materials can be polished to form "sharp cutting edge."

Q: What are the benefits of diamond tools?

Advantages. Diamond is one of the hardest natural materials on earth; much harder than corundum and silicon carbide. Diamond also has high strength, good wear resistance, and a low friction coefficient. So when used as an abrasive, it has many obvious advantages over many other common abrasives.

Q: How are diamond tools made?

High-quality Diamond cutting tools are manufactured with electrolytic iron powder where it acts as a part of the binder alloy and offers the specific arrangement of the diamond composites on to the surface of the tools.

Q: How do diamond tools work?

The actual grinding work is done by exposed diamond crystals that are held in place by the metal matrix or bond. Each diamond is supported by a bond tail which trails behind the diamond. While the blade rotates through the material, the exposed diamonds on the surface grind the material.
