High-precision Flat Lapping CBN Wheel

Vitrified-bond CBN wheels allow for highly efficient flat lapping in addition to creating extremely high-precision flat surfaces.


  • High precision can be maintained and machining time can be greatly reduced.
  • Chip removal occurs smoothly thanks to a groove in the middle of the tip, avoiding clogging and deposition.
  • Machining efficiency can be greatly improved thanks to the tip edge.
