CBN Wheel

Square Edge CBN Wheel

Our CBN wheels are perfectly balanced, dead flat, and have better tolerance specifications than others’

Round Edge CBN Wheel for both curved and straight blades

Round Edge CBN Wheel

Our all-aluminium CBN wheels run with tap water on all slow wet grinders : Tormek, Scheppach, Jet, Record, Grizzly, Triton, Saber, WEN, Holzmann NTS 250PRO etc. Suitable for all knife and tool steels.

CBN wheels are the single biggest advance in sharpening in a very long time

Cubic boron nitride (CBN) properties include extreme hardness, stability under heat, and superior chemical resistance.

Cubic boron nitride is the second-hardest known material on the planet (after diamonds), but has higher heat and impact resistance than diamonds, and therefore CBN is preferred over diamond in industrial applications.

CBN perfects in sharpening hard alloy, tool and high-speed steels, as well as ceramic blades, and has advantage over conventional abrasives in sharpening carbon and mainstream stainless steels, delivering a superior edge compared to the stone wheel. CBN superabrasives remove material in a unique way; due to their super hardness the whole process is quite similar to the milling operation, while conventional abrasives like aluminium-oxide and silicon-carbide have more similarity with sanding. Thanks to that the CBN wheel produces smaller burr and sharper edge apex as compared to aluminium oxide and silicon carbide. Comparison between conventional abrasives (aluminium oxide or silicon carbide) and CBN cubic boron nitride reveals that for conventional abrasives burrs tend to be of a long and thin shape whereas for superabrasives the burrs tend to be relatively small and thick.

Grinding on the 250 mm wheel gives a near flat edge, with very little concavity; the CBN layer on the sides of the wheel allows for completely flat grind.

WHICH GRINDING WHEEL IS FOR YOU

Woodworking tools: #80 and #400 wheel. For fine carving chisels also #1000.

Knife sharpening : - kitchen, butcher and alike knives: #80 followed by #400 - then deburring; - high end knives: bevel on #160 and #400, set the edge apex on #1000 wheel - then honing & deburring;

If you often repair dents, reprofile bevels, or do first-time sharpening for knifemakers, you will benefit from an extra wheel of #80 for quick steel removal.

USAGE

  • Our CBN wheels can be run with tap water or metal-working fluids, or dry.
  • CBN crystals are embedded in nickel, electroplated onto the aluminium wheel base, and this nickel-CBN layer does not withstand hard impact. We have noticed that hits against the Universal Support bar and shaft of your Tormek when removing the wheel are common with the beginners.
  • Sharpen with a low pressure. Maintain firm contact of the blade with the wheel, but never press hard, as excessive pressure may strip off the CBN crystals. The easiest way to control pressure is by watching nailbeds of your fingers on the blade – they should remain pink; when you press too hard, the rim of your nailbeds turns white because of blocked blood flow in the nailbed capillaries.
