CBN abrasive belts

The new CBN abrasive belts are suited especially for work with hardened steels (>55 HRC) and titanium alloys. Next to diamonds, CBN (cubic boron nitride) is the hardest abrasive grain.

Because of the hardness of the CBN abrasive grain, the new CBN abrasive belts achieve outstanding results on hardened steels, chrome (layers), carbon metals, grey cast iron.

Product features

  • Very long service life
    The combination of the innovative grain technology and the belt joint technology as well as the very limited grain wear ensure a very long service life for the CBN abrasive belts.
  • Treatment of very hard materials
    Because of the extreme hardness of the CBN crystals, very hard materials can be treated. The wear and corrosion resistance of the CBN crystals ensures high machining capacity.
  • Consistent surface quality
    The continuous grinding output with an extremely long service life ensures a consistent surface quality. The very cool grinding prevents thermal damage to the surface of the workpiece.
  • Suitable for dry and wet grinding
    The CBN abrasive belts are suited for both, dry and wet grinding.


The CBN abrasive belts have a special patented support material, called aramid fibres. Aramid fibres (also known under the brand name, kevlar) are characterized by their high strength, a very high elongation and a high capacity to dampen vibrations. The support material is applied with a formfitting copper layer. With a nickel base alloy, the CBN crystals are bonded to the abrasive belt galvanically, strewn in a regular intermittent pattern or with no spacing, covering the entire surface (see fig.s).

Grain size comparison

The designation of the CBN grain size differs from the grain size according to FEPA. For a better allocation and selection of the correct grain size for the CBN abrasive belts, a grain size comparison is shown in the illustration below.


  • CBN: Hardened steels, chrome (layers), carbon metals, grey cast iron
  • Recommended grinding:Grinding of surfaces, edges and cylindrical workpieces
  • Types of workpieces:Rollers, (paper) cylinders, glass edges, marble and granite slabs, ceramic coated elements
  • Operations: Robots, automated grinding and grinding by hand
