CNGA CBN Inserts – Premium Cubic Boron Nitride Cutting Inserts
Key Advantages
Extreme Hardness: Second only to diamond, enabling efficient machining of materials up to 65 HRC while maintaining edge sharpness.
Superior Thermal Stability: Withstands temperatures up to 1,400°C (2,552°F), resisting thermal cracking in high-speed cutting scenarios.
Extended Service Life: 3–5x longer than carbide or ceramic inserts, minimizing tool replacement downtime and reducing overall machining costs.
Versatile Applications: Adaptable to automotive mass production, aerospace component machining, and precision hard turning.
1.Single-edged tool tips are ideal for low-volume production of high-precision workpieces. Tools with a back angle can significantly enhance CBN cutting performance, while coated CBN edges further extend tool longevity—making them a premium choice for precision-centric applications requiring optimal durability and efficiency.
2.Double-edged tool tips are engineered for high-volume production of ultra-precision components. CBN inserts with back angles and optional coatings deliver extended tool life, reduced wear, and consistent performance—ideal for manufacturers balancing throughput and tight tolerances in demanding applications.
Notes: Edge rounding W=0.15mm; customizable for different workpiece materials.
Application Scenarios
- Hard Turning: Gear shafts, bearings, dies, molds (grinding-free precision)
- Automotive Industry: Brake discs, crankshafts, hardened automotive components (high-volume production)
- Aerospace Industry: Heat-resistant superalloys (Inconel, titanium) precision cutting
- General Engineering: High-precision finish machining of hardened parts
