High-temperature Resistant CBN Insert
In the demanding world of precision machining, where ferrous alloys push tools to their limits, thermal stability is not merely an advantage—it's a requirement for success. Our High-temperature Resistant CBN Insert is engineered specifically to excel in these extreme environments, maintaining its cutting edge integrity where conventional tools fail. This insert is the cornerstone for machining hardened steels, cast irons, and superalloys, delivering unparalleled performance and extended tool life. For applications demanding ultimate material integrity, our High-hardness CBN Insert provides the necessary durability. When micron-level accuracy is non-negotiable, the High-precision CBN Insert ensures flawless finishes. In operations prone to intermittent cuts or vibration, an Impact-resistant CBN Insert is essential for reliability. Ultimately, for all ferrous metal machining challenges, our comprehensive CBN Insert for Ferrous Metals lineup offers a specialized solution.
The core innovation of the High-temperature Resistant CBN Insert lies in its advanced composition and robust design. It utilizes a premium cubic boron nitride (CBN) content, strategically bonded with a ceramic phase that provides exceptional thermal and chemical stability. This unique structure allows the insert to withstand continuous cutting temperatures exceeding 1200°C without significant wear or deformation. The substrate is crafted from a specially formulated tungsten carbide, offering superior support and heat dissipation to protect the CBN layer. A proprietary post-treatment process further enhances the edge strength and surface quality, ensuring consistent performance from the first cut to the last. This makes the High-temperature Resistant CBN Insert an indispensable tool for high-speed dry machining, hard turning, and milling applications where heat is the primary adversary.

| Insert Style | CBN Content | Recommended Cutting Speed (m/min) | Feed Rate (mm/rev) | Depth of Cut (mm) | Typical Workpiece Material |
|---|---|---|---|---|---|
| CNGA / RNMN | High (CBN50+) | 80 - 250 | 0.05 - 0.20 | 0.1 - 0.5 | Hardened Steel, Tool Steel |
| SNMA / TNMG | Medium (CBN30) | 100 - 300 | 0.08 - 0.25 | 0.2 - 1.0 | Gray Cast Iron, Chill Cast Iron |
| RCMX / CCGT | High (CBN50+) | 150 - 400 | 0.03 - 0.15 | 0.05 - 0.3 | Powder Metal, Sintered Iron |
For optimal results with the High-temperature Resistant CBN Insert, a rigid machine tool setup with minimal runout is critical. Use positive rake geometries for lower cutting forces and reduced heat generation. A consistent, high-pressure coolant directed at the cutting zone is recommended, though the insert is fully capable of dry machining. Always ensure the workpiece is securely clamped to prevent vibration, which can compromise edge life and surface finish. Implementing these best practices will maximize the productivity gains and cost-effectiveness provided by this advanced cutting tool.
