CeramTec CBN — Hard Turning Solutions
💎 When the workpiece becomes harder, the cutting material has to become smarter.
Hard turning places enormous demands on a cutting edge.
High hardness, heat generation and the need for extremely accurate finishes mean that conventional tooling may not always be the most efficient solution.
That is where CBN — Cubic Boron Nitride — cutting materials become extremely valuable. ⚙️
CeramTec’s CBN solutions are designed for demanding hard-turning applications where high wear resistance, dimensional accuracy and consistent surface quality are critical.
CBN is one of the hardest cutting materials used in machining and is particularly well suited to hardened materials where stability and tool life become essential.
🔴 Why CBN for hard turning?
💎 Excellent wear resistance
🎯 High dimensional accuracy
✨ Excellent surface-finish capability
🌡️ Strong performance under demanding thermal conditions
⚙️ Suitable for precision machining of hardened components
Typical applications can include hardened gears, bearing components, shafts and other precision components where grinding may traditionally have been considered the only finishing option.
In the correct application, hard turning with CBN can provide an extremely efficient alternative machining strategy.
But CBN is not simply a case of “use the hardest insert.”
Grade selection, edge preparation, machine rigidity, cutting conditions and workpiece hardness all matter. That is why technical support is just as important as the insert itself.
