Vitrified Bond CBN Double Disk Grinding Wheel

Item Name: Vitrified Bond CBN Double Disk Grinding Wheel

Size Range: 600mm~1500mm

CBN Shape: cylindrical, hexagonal, fan-shaped, square

Applications: Suitable for precision grinding of high-speed steel, bearing steel, tool steel, stainless steel powder and metallurgy cast iron, etc.


The ceramic bond CBN double-sided grinding wheel has the characteristics of long service life and low grinding cost, which can greatly improve the grinding efficiency, flatness and parallelism, and the roughness of the processed products can fully meet customer requirements.


  • High grinding efficiency, high precision required in a short time.
  • High wear resistance (less abrasive consumption, especially when grinding M2 high speed steel workpieces).
  • High grinding force and low grinding temperature.
  • No scratches, no pitting on the surface of the workpiece.
  • Grinded workpiece with high precision, good surface quality and good flatness.
  • Long service life long, reduce grinding disc wheel changed frequently.


Crownkyn Superhard Ceramic Bond CBN Grinding disk is used for precision grinding of high-speed steel, bearing steel, tool steel, and stainless steel powder metallurgy cast iron.

Typical workpieces include: high-flatness workpieces such as air conditioner refrigerator compressor slides, valve plates, automotive steering pumps, vanes, rotor stator gauge blocks, and thin-walled bearings.

Supporting equipment: Suitable for the double disk grinding machine produced by our company. It is also used on Germany Peter Walter, South Korea AM, UK Laimat and other domestic and foreign double-face grinder.
