CBN Insert PCD Insert CBN Tools PCD Tools

Polycrystalline diamond is extremely hard and is produced by sintering together selected diamond particles with a bonding matrix under high pressure and temperatures. As a result of its extreme hardness and toughness, PCD is extremely wear-resistant and has high thermal conductivity. The combination of the excellent hardness and wear properties of the diamond with the strength properties of the carbide makes PCD a cutting tool material that permits metal cutting performance up to the very limits of today’s the machine tools and metal cutting systems.

CBN CUTTING INSERTS

Cubic boron nitride is the second-hardest known material after diamond, and as such, is ideal for cutting tools that wears far more slowly than those with other cutting tool materials. We therefore achieve a very high degree of shape and dimensional accuracy and can machine hard materials such as steel more reliably.
