DICTUM CBN Grinding Wheel Black Crystal, Ø 150 mm, One Side Coated, B91
With the CBN grinding wheels you can sharpen even HSS (also powder metallurgically produced) and hardened steel on the slowly running double grinder without the risk of the steel getting too hot. A special process allows grinding without coolant. With only slight pressure you achieve an excellent rate of stock removal and stunning grinding results. Coated with black CBN crystals for extra long service life when sharpening hardened tool steels. The wheels are made of steel and exactly balanced. Optimal speed range 1700 up to max. 3000 rpm. Can be used on e.g. DICTUM low-speed grinder (clamping sleeve No. 707837 and DICTUM Superflange No. 704850 needed, available online) or Creusen double-wheeled grinder.
For additional applications, like grinding chisels (turning tools) without hollow grind, the side of the wheel is also coated to approx. 17 mm wide.
CBN Coating
CBN stands for Cubic Boron Nitride, an abrasive grain that is nearly as hard as diamond but much better suited for sharpening hardened steel. Sharpening on diamond wheels produces heat, and from around 170 °C causes a chemical reaction between the diamond grain and the steel alloys which destroys the diamond grain. CBN, on the other hand, only reacts at above 400 °C, and is only destroyed at 700 °C and above.
