BZN® VS-Series

Hyperion BZN VS-Series polycrystalline cubic boron nitride (PCBN) Hyperion Materials & Technologies' newest addition to the BZN® family of polycrystalline cubic boron nitride (PCBN) grades is the VS-Series. These are a complement to the BZN V-Series, which is widely viewed as the benchmark of hardened steel machining grades. The BZN VS-Series offers significantly improved edge toughness while maintaining superior crater and abrasion resistance.

The BZN VS-Series has the following key attributes: 

  • Improved toughness and chipping resistance
  • Solid PCBN (no carbide support)
  • Flexibility in tool design and geometry
  • Because there is no carbide support, there is no coefficient of thermal expansion mismatch during tool fabrication
  • Ability to handle applications with increasing interruption levels or chip loads with more consistent tool life.
