Synthetic CBN Powder
Synthetic CBN Powder has the highest thermal stability and is second only to diamond in hardness, which is with combination of toughness, chemical and thermal stability.
The Application Of Our Synthetic CBN Powder
Synthetic CBN Powder Application Characteristics
- Efficient Precision Machining
Monocrystalline CBN has sharp cutting edge and high strength, which is suitable for high-efficiency grinding of high hardness and toughness materials (e.g. hardened steel);
Polycrystalline CBN has even cutting edge, which can improve the dimensional accuracy and surface quality of complex shaped workpieces.
When combined with ceramic bond, it can realize high-speed, high-precision grinding and avoid workpiece burns and deformation.
- Wide applicability
Used in automotive, aerospace and other fields, especially in titanium alloy, stainless steel, alloy steel processing irreplaceable
Advantages Of Synthetic CBN Powder
Synthetic CBN Powder Features
1. Ultra-high hardness and wear resistance
Microhardness up to HV7000-8000 (Mohs hardness 9.7, Vickers hardness about 7500), second only to diamond; high grinding ratio, greatly extending tool life
2. Excellent thermal stability
remains chemically inert at 1300°C, and the boron oxide layer on the surface reduces the coefficient of friction;
3. Outstanding thermal conductivity
has a high thermal conductivity of 1300 W/(m-K), which is quickly exported when grinding. Outstanding thermal conductivity Thermal conductivity of up to 1300 W/(m-K), rapid export of heat during grinding, significantly reducing the risk of thermal damage to the workpiece
4. Low chemical affinity
has a very low affinity for ferrous elements (e.g. iron, nickel), which avoids adhesion when grinding ferrous metals and is particularly suitable for processing hardened steel (HRC≥60).
