What is Coated CBN Powder?
Coated CBN powder refers to synthetic cubic boron nitride particles that are uniformly coated with metal or compound layers such as nickel, copper, or titanium. These coatings significantly enhance the CBN’s thermal resistance, bond retention, and durability during high-temperature and high-speed machining processes, particularly on hardened ferrous materials.
At Crownkyn Diamond, we focus on delivering high-performance coated CBN powders with consistent coating quality, precise particle size distribution, and stable performance. Our coating options are tailored to meet the specific requirements of tool manufacturers, helping improve grinding efficiency, reduce wear, and extend the service life of resin, metal, and vitrified bond tools.
Key Features and Benefits of Coating CBN Powder
Coated CBN powder offers enhanced bond retention, superior thermal stability, and protection against chemical wear during the grinding of ferrous materials. The uniform metal coating strengthens the bond between CBN particles and the binder, reducing grain pull-out and improving tool integrity. This results in extended tool life, consistent cutting performance, and greater resistance to heat and mechanical stress—ideal for demanding industrial applications requiring precision and durability.
Enhanced Bond Retention
The uniform metal coating strengthens the bond between CBN particles and the tool matrix, effectively reducing grain pull-out and improving tool life in demanding grinding conditions.
Improved Thermal Stability
Coatings such as nickel or titanium shield CBN particles from thermal degradation, maintaining abrasive performance and structural integrity under high-temperature operations.
Better Heat Dissipation
Coated CBN facilitates efficient heat transfer during machining, helping to minimise thermal damage to both the workpiece and the tool, while improving overall grinding efficiency.
Consistent Coating Quality
Tightly controlled manufacturing processes ensure uniform coating thickness, stable particle morphology, and reliable batch-to-batch performance, critical for precision applications.
Versatility Across Bond Systems
Engineered for use with resin, metal, and vitrified bond tools, coated CBN powder is suitable for precision grinding, honing, and finishing of hardened steels and other ferrous materials.
Coating Types and Their Functions
Crownkyn uses advanced coating technologies to enhance the performance of diamond powder. Depending on the coating material and the specific application, we apply one of three methods, each offering distinct advantages to meet different bonding systems and processing requirements.
A uniform, auto-catalytic process that deposits metals like Ni or Cu evenly on the CBN surface without electricity. Ideal for micron and irregular-shaped CBN particles, this method enhances wettability, bond retention, and dispersion in resin and bronze bond systems.
An electric-current-assisted technique used to apply coatings such as Ni or Ni-Co. This process provides strong adhesion and precise control of coating thickness, making it suitable for electroplated tools and applications requiring tight particle bonding and consistent grit retention.
A high-temperature vapour-phase process that forms carbide-forming coatings like Ti, Cr, or TiC on the CBN surface. CVD coatings deliver excellent thermal stability, oxidation resistance, and chemical protection—ideal for vitrified and metal bond tools used in aggressive, high-temperature grinding operations.
Available Grit Sizes, and Coating Thickness
Coated CBN powder is available in a full range of grades, grit sizes, and coating thicknesses, each engineered to suit specific grinding and machining applications. Choosing the appropriate combination is critical to achieving strong bond retention, enhanced thermal resistance, and consistent performance under high loads and temperatures—ensuring your tools deliver optimal efficiency and service life.
Available Grit Sizes
Coating Thickness
Bond System Compatibility
Coated CBN powder is designed for stable integration into various bond systems used in high-performance grinding and machining of ferrous materials. Each coating type enhances the interaction between the CBN grain and the bond matrix, contributing to tool strength, durability, and efficiency.
Resin Bond
Coated CBN enhances mechanical retention within the softer resin matrix. The coating improves thermal resistance and reduces grain dislodgement during grinding, making it ideal for precision applications and contour grinding.
Vitrified Bond
In vitrified systems, the coated surface provides excellent thermal and chemical stability. It supports sharpness retention and consistent performance, even in dry grinding or at elevated temperatures.
Metal Bond
The coating improves interfacial bonding between CBN particles and the metallic matrix, while also enhancing heat conductivity. This results in higher wear resistance and prolonged tool life, especially in high-load conditions.
Electroplated Bond
Coated CBN particles, especially those with electroplated nickel or nickel-cobalt coatings, offer strong adhesion to the plating layer. This ensures firm grit holding and sharp edges, essential for precision electroplated grinding wheels and dressing tools.
Typical Applications in Various Industries
Crownkyn’s coated diamond powder is widely used across industries that demand high precision, durability, and efficiency. With coatings such as Ti, Ni, W, Cu, Cr, Co, TiC, and Si, our products deliver enhanced bond retention, thermal stability, and tool life for a range of applications:
- Automotive & Aerospace：Precision grinding of hardened steel components such as gears, crankshafts, camshafts, and turbine parts, where coated CBN ensures thermal stability and prolonged tool life.
- Bearing & Transmission Manufacturing：Finishing and superfinishing of bearing races and transmission parts made from alloy or tool steel, requiring high dimensional accuracy and surface integrity.
- Tool & Die Industry：Internal and external grinding of mould components and die steels using resin or vitrified bonded tools reinforced with coated CBN for reliable edge retention.
- Machine Tool Reconditioning：Restoration of worn components such as spindles and guides made of ferrous materials, where coated CBN supports consistent performance under varying loads.
- Industrial Knives & Blades：Sharpening and profiling of cutting tools and industrial blades made of high-speed steel (HSS) or D2 steel, where coated CBN provides stable cutting edges and reduced thermal damage.
With consistent particle shape, controlled size distribution, and broad bond system compatibility, Crownkyn’s crushed diamond powder helps tool manufacturers deliver reliable performance across multiple industries.
How to Select the Right Coated CBN Powder
STEP 1
Match the Bond System
Select coatings that suit your bond type: Ni for enhanced retention in resin and electroplated bonds, Ti for thermal protection in metal and vitrified bonds, and Cu for improved heat dissipation and bonding in resin and metal systems.
STEP 2
Identify the Workpiece Material
Consider the type of ferrous material being processed—such as tool steels, alloy steels, or superalloys—and assess the application’s load, speed, and temperature to determine the best grit characteristics for your operation.
STEP 3
Choose the Right Grit Size
Fine grit sizes (micron) are best for honing and precision finishing; medium grit sizes for standard grinding tasks; and coarse mesh sizes for aggressive stock removal or shaping operations.
STEP 4
Determine Coating Thickness
Select from standard coatings (30–60% by weight) based on your process. Thicker coatings offer enhanced bond retention and heat resistance, while thinner coatings provide better sharpness and cutting efficiency in lower-load applications.
STEP 5
Request Sample Evaluation
Collaborate with Crownkyn’s technical team to evaluate coated CBN samples under real-world conditions. This ensures the selected grade, grit size, and coating thickness meet your tool performance and productivity goals.
Quality Control and Consistency
At Crownkyn, we enforce strict quality control to ensure uniform coating, consistent grit size and reliable performance in every batch of coated CBN powder. This supports stable and repeatable results in your tool production.
Uniform Coating Quality: Advanced plating techniques ensure each CBN particle is coated evenly, verified through SEM and thickness control, providing strong bond retention and stable thermal performance.
Precise Size and Shape Control: Laser particle analysis and precision sieving are used to achieve consistent grit size and shape, supporting predictable tool behaviour and consistent grinding results.
High Purity Standards: ICP and XRF analysis help control impurities, protecting tool integrity and ensuring stable performance during high-temperature machining.
