Product description:

Why is CBN?

CBN is superior to all other materials for grinding hardened steel, it hardly generates a high temperature, because CBN has an extremely good conductivity for temperature. This is also helped by the shape of the metal body of the wheel.

For woodturning wheel, there are two types. One is a mix of abrasive and a bonding agent, which is applied to an aluminum hub in a layer. The other type is a machined steel hub with the abrasive material plated to the surface of the wheel.

Application:

Differently from aluminum oxide grinding wheels, woodturning CBN sharpening wheel cuts fast, stays cool and never needs dressing or shaping. With only a very light amount of pressure when 
sharpening and proper care, you can sharpen your tools to a razor sharp edge and never need to buy another sharpening wheel again.

Speed:

At what speed should CBN wheels run? The wheels are balanced, just like a wheel to your car, so that they do not cause vibrations at higher revs. CBN wheels perform best at the following speeds: a 150 mm wheel – rpm between 1700 and 3000 rpm. A 200 mm wheel between 1400 and 2100 rpm and a 250 mm wheel between up to 1450 rpm. In general, you can say that a CBN wheel performs better if the speed is higher up to the above-mentioned limit. The 250 mm wheels though work brilliant on the slow speed grinders like the Tormek T7 and T8. It works very well.
