CBN Grinding Wheel

CBN grinding wheel from Diamet

This grinding wheels consist of a steel body which is coated with CBN on the circumference and on one side approx. 17mm wide. After diamond, CBN is the second hardest known material. It is great for grinding steel. The big advantage over conventional corundum grinding wheels is that the tools hardly heat up when used properly. The resulting heat is dissipated very well through the steel body. With very little pressure (not much more than the weight of the tool), not only are excellent stock removal rates, but also an amazingly good finish and an excellent cutting edge.

There are almost no sparks when grinding HSS, and very few when machining hardened steel. "Burning" of the tool is almost unknown. The extraordinary hardness of the abrasive grain ensures an extremely long life of the sharpening wheels if handled correctly. When used correctly, tools made from CBN wear out much more slowly than other cutting materials.

The application speed should be at Ø 150mm at approx. 1,900 - 2,500rpm and at Ø 200mm at approx. 1,500 - 2,000rpm
The diameter of the discs is 150 or 200mm, the Width 20, 25 or 40mm. Please select the desired dimensions.
Grain size B91 (corresponds to approx. 180 grain), suitable for HSS tools.
The diameter of the mounting hole is 32mm. The length of the hole inside is 20mm (the same for all pane widths).

As accessories, we offer mounting flanges (reducing sleeves) for smaller shaft diameters. There is also a mount for M33 x 3.5 thread.
