Description
This CBN grinding wheel has been specifically designed for use on wet grinding machines, such as the DICTUM water-cooled grinder and the Tormek T-7/T-8. The CBN-coated, precisely balanced aluminium body allows grinding without water or coolant. This saves time and keeps the workstation dry. With only slight pressure you can achieve an excellent rate of stock removal and stunning grinding results. There is no risk of annealing with HSS and hardened steels. Coated with black CBN crystals for extra long service life when sharpening hardened tool steels.
CBN coating around the circumference, for all standard sharpening work on the water-cooled grinder.
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.
