Vitrified Diamond and Vitrified CBN grinding wheels combine the hardest known superabrasives held mechanically and chemically in glass (ceramic bond) to form some of the most highly efficient grinding products available on the market.

The combination of the vitrified bond's high thermal stability and its ability to control wheel structures allows for more effective coolant delivery to the grinding zone, resulting in minimization of thermal damage to the work piece. 

Most commonly employed in the grinding of PCD and PCBN tools, Vitrifed Diamond grinding wheels have enabled polycrystalline tool fabricators to obtain excellent surface finishes, quickly and productively. Vitrified grinding wheels can also be used in the fabrication of natural diamond, as well as many dense ceramic materials.

The very nature of vitrified bonds allows for the custom tailoring of a grinding wheel structure specific to a customer's material and grinding process, resulting in an efficient grinding process where wheel life and cycle times are optimized for lowest costs and highest work piece quality.

Vitrified Grinding Wheels provide: 

  •  100-300 Times the Life of conventional grinding wheels  in comparable applications.

  • Efficient Heat Removal with open structures that carry coolants into the work zone resulting in less thermal damage to metals when compared with other bond systems.

  • Improved Cycle Times Decreased down time, wheel dressing and/or wheel changes when compared with conventional and resin bonded superabrasive applications.

  • Adaptable Aggressive, free cutting bond adapts to various spindle speeds.

  • Lights Out Operation is possible with dressable structures as layer depths allow for continual renewing of the grinding layer. 

  • Re-Truing of Formed Profiles and formed structures are possible using Diamond tools and rotary dressers.

  • Customization of grinding wheel specifications for specific customer applications.

Ideal for:

  • Camshaft & Crankshaft

  • PCD/PCBN Cutting Tools

  • Mold & Dies

  • Turbine Blades, Vanes, Shrouds

  • Medical Instruments

Superabrasives vs.
conventional abrasives

Each wheel type has a place in manufacturing: there are softer materials that superabrasive wheels will not grind that conventional wheels can. But for materials harder than 30’s HrC, a superabrasive wheel is the most cost effective option. Superabrasive wheels do not wear away like conventional wheels do, therefore grinding waste is greatly reduced.
