CBN Abrasive Sandpaper
CBN Sandpaper Sheet

ality surface finish and long service life. This makes it an ideal choice for woodturners,metalworkers, and other professionals who require high-quality abrasive paper for their work.
CBN coating sandpaper is a type of abrasive paper that is coated with cubic boron nitride (CBN) particles. This coating makes the sandpaper highly durable and efficient in grinding and polishing hard materials such as metal alloys, titanium alloys, stainless steel, and high-temperature alloys. CBN abrasive paper is also known for its ability to maintain a low grinding temperature, which prevents overheating and damage to the workpiece.
Woodturners sandpaper is a specific type of
CBN abrasive paper that is designed for use in woodturning applications. Woodturners require abrasive paper that is gentle on wood but still effective in removing imperfections and creating a smooth surface. CBN abrasive paper is an excellent choice for woodturners because it is gentle on wood and produces a high-quality surface finish.
CBN abrasive sheets are available in a range of grit sizes, from coarse to fine. This allows professionals to choose the appropriate grit size for their specific application. The high grinding efficiency of CBN abrasive paper means that less pressure is required to achieve the desired result, which reduces the risk of damage to the workpiece.
In conclusion, Diamond
CBN Sanding Abrasive Grinding Polishing Paper is a highly effective and durable abrasive paper that is suitable for use on a variety of hard materials. Its high grinding efficiency, good wear-resistance, low grinding temperature, high-quality surface finish, and long service life make it an ideal choice for professionals in the woodworking and metalworking industries. Whether you are a woodturner or a metalworker, CBN abrasive paper is an excellent choice for your abrasive paper needs.

Features of CBN

1, The hardness of CBN is much higher than ordinary abrasives. Especially for processing high hardness, toughness, high temperature, high strength, low thermal conductivity of the material. The metal grinding rate of CBN is 10 times of the diamond.

2, CBN abrasive grinding performance is very excellent, not only capable of grinding materials that is difficult to work, improve production efficiency, but also conducive to strictly control the shape and size of the workpiece precision, and effectively improve the grinding quality, significantly improve the grinding the surface integrity of the tool, thus increasing the fatigue strength of the part, extending the service life and increasing the reliability.

3, CBN abrasive grinding has wear less, long cycle, grinding ratio is relatively high, and has a reasonable economic result.

4, The shape and size change of CBN abrasive is extremely slow when using, which is more suitable for CBN CNC machining high-precision parts.

5, It can maintain a sharp grinding force for long time, so the grinding force is small. It is better for improving accuracy of parts and finish. and also can reduce the power consumption of machine tools.

6, The grinding temperature is low, can greatly improve the surface quality of the workpiece, to avoid parts of cracks, burns, changes in tissue , improving the processing of surface stress, it is good for the extension of the life of parts.

7, Ordinary abrasive  produce a lot of dust when using, it is harmful to human health. It will cause silicosis if long term use.

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: CBNabrasive 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.
