The application of Cubic Boron Nitride mainly includes the following aspects:
Ⅰ Cutting Tool Materials
① Processing hardness steel:
Polycrystalline cubic boron nitride(PCBN)cutting tools are capable of handling the rough turning and finish turning of hardened steel. For example, they can be used for machining the fork grooves of carburized and quenched gears in automotive engine components. They can achieve grinding replacement by turning, improve processing efficiency and accuracy, and reduce processing costs.
② Processing cast iron:
They are suitable for machining various cast iron materials, such as gray cast iron, ductile cast iron, and vermicular cast iron. They can effectively improve the machining surface quality and the durability of cutting tools and are widely used in the machining of components like automotive engine blocks and cylinder heads.
③ Processing superalloys and cemented carbides:
For difficult-to-machine materials such as superalloys and cemented carbides, PCBN cutting tools can also exhibit excellent cutting performance, enabling high-speed cutting and meeting the requirements for high-precision and high-efficiency machining in fields like aerospace and mechanical manufacturing.
Ⅱ Abrasive Tool Materials
① Precision grinding:
CBN micro-powder can be used for precision grinding, lapping, polishing and superfinishing. It can achieve a high-precision machined surface quality and is suitable for processing various high-hardness and high-precision parts, such as aero-engine blades and bearings.
② Grinding of metallic materials:
CBN abrasive tools have good grinding performance for ferrous metals, especially for materials with high hardness, high toughness, high strength at high temperatures and low thermal conductivity. Its metal removal rate is 10 times that of diamond. It can be used for grinding hardened steel, high-speed steel, tool steel, etc., improving the grinding efficiency and quality.
③ Grinding of ceramics and glass:
In the grinding process of hard and brittle materials such as ceramics and glass, cubic boron nitride abrasive tools also perform excellently. They can effectively avoid cracking and breakage of the materials, improving the machining accuracy and surface integrity.
Ⅲ Electronic field
① Electronic device packing:
Taking advantage of its excellent insulating and thermal conductive properties, it can be used as an additive for electronic device packaging materials to improve the thermal conductivity and insulation performance of the packaging materials, which helps with the heat dissipation and stable operation of electronic devices.
② Semiconductor manufacturing:
During the semiconductor manufacturing process, cubic boron nitride can be used to make grinding discs, cutting blades and other tools for grinding, cutting and other processing procedures of semiconductor materials to ensure the processing accuracy and surface quality.
Ⅳ Other fields
① Optical component processing:
It can be used for the processing of materials such as optical glass and crystals to manufacture high-precision optical lenses, prisms and other components, meeting the requirements of the optical instrument manufacturing industry for component accuracy and surface quality.
② Gemstone processing:
In gemstone processing, cubic boron nitride cutting tools and abrasive tools can be used for cutting, grinding and polishing various gemstones, such as diamonds, rubies, sapphires, etc., improving the processing efficiency and quality and reducing the processing costs.
③ Petroleum drilling:
Its high hardness and wear resistance make it suitable for the petroleum drilling field. It can be used as the material for petroleum drilling probes to improve the drilling efficiency and the service life of the drill bits.
