Solid PCBN Cutting Tools

Solid PCBN Cutting Tools (PCBN Series) JCB PCBN Series Solid PCBN Cutting Tools represent a high-performance class of superhard material designed for machining hard steels, cast iron, and superalloys. Composed of 100% polycrystalline cubic boron nitride (PCBN) without a carbide substrate, these tools exhibit exceptional heat resistance, extreme hardness, and excellent chemical stability, making them suitable for both continuous and interrupted cutting operations. Manufactured under high pressure and temperature using pure CBN and binders derived from lab-grown diamond or other synthetic diamond sources, the tools achieve a dense and robust polycrystalline superhard materials structure. Unlike conventional diamond cutting tools such as those based on CVD diamond, single crystal diamond, or other monocrystal superhard material solutions, solid PCBN offers superior thermal stability and edge retention even at elevated temperatures. This makes them especially well-suited for dry and heavy…
