1. What is CBN Grinding wheel?

CBN grinding wheel is a type of grinding tool that uses cubic boron nitride (CBN) particles as abrasives. It has extremely high hardness and wear resistance, and is widely used in various processing industries.

2. Characteristics of CBN grinding wheel

1)  Ultra-high hardness: The hardness of CBN grinding wheels is several times higher than traditional aluminium oxide grinding wheels, which can reach 15,000-20,000MPa, so it is able to process harder materials.

2)  Excellent abrasion resistance: CBN particles are extremely abrasion-resistant, which makes CBN grinding wheels maintain good cutting results after a long time of use.

3)  Low coefficient of friction: Due to the low friction between the CBN particles, there is no excessive frictional heat generated during the machining process, which reduces the deformation of the surface of the machined parts and residual stresses and frictional losses during machining.

4)  Excellent electrical conductivity: CBN particles have good electrical conductivity, which can effectively release the static electricity generated during machining to avoid problems caused by static electricity.

3. The advantages of CBN grinding wheels in use

1)  Efficient trimming: Due to the high hardness of steel, it is difficult for conventional abrasives to effectively trim it. CBN grinding wheels have extremely high hardness and wear resistance, which can quickly repair the surface of steel and improve processing efficiency.

2)  High precision machining: CBN grinding wheels have excellent cutting performance and stable machining quality, which can achieve precision machining of steel, ensuring dimensional accuracy and surface quality of machined parts.

3)  Long lifespan: Due to the high hardness and wear resistance of steel, it often leads to rapid tool wear during traditional machining processes. CBN grinding wheels have extremely strong wear resistance, which can effectively extend their service life and reduce production costs.

4)  Wide application range: CBN grinding wheels can not only be used for steel processing, but also for processing other hard materials, such as high-speed steel, alloy steel, cast iron, etc., with strong universality.

4. Application fields of CBN grinding wheels

1)  High hardness material processing: CBN grinding wheels are suitable for processing various high hardness materials, such as high-speed steel, hard alloys, ceramics, etc.

2)  Precision machining: Due to the extremely high precision and stability of CBN grinding wheels, they are widely used in industries that require precision machining, such as aerospace and automotive manufacturing.

3)  Grinding complex surfaces: CBN grinding wheels have strong self-sharpening performance and can be used to process various complex surface parts, such as gears, camshafts, crankshafts, etc.

4)  Ultra-precision machining: Due to the extremely small and uniform distribution of CBN particles, CBN grinding wheels can achieve ultra precision machining effects and are widely used in industries such as optical instruments and electronic devices.
