150 х 25 х 7 x 3 x 4
CBN (nitruro de boro cúbico) es un nombre genérico, también existen otros nombres para este material, según el fabricante: borazon, elbor, cubonita, etc.
El CBN (nitruro de boro cúbico) es el segundo material más duro después del diamante y tiene la mejor relación precio-rendimiento para procesar aceros, en comparación con otros materiales, incluidos el diamante, el carburo de silicio o el óxido de aluminio.
Debido a sus especificaciones de alta resistencia, el CBN se puede utilizar en seco sin lubricante. Esto convierte al CBN en la piedra de afilar más limpia disponible.

Preparation of sharpening stones
A diferencia de otras piedras de afilar, la mayoría de estas piedras de afilar combinadas no necesitan preparación, excepto las piedras con granos más finos de 1 micra (<Grit 15000). Los granos ultrafinos (1/0, 0,5/0) forman aglomerados en una unión, por lo que es posible que deba revestirlos con polvos/pastas abrasivos, o se autopulirán después de afilar entre 30 y 50 cuchillos.

Use and cleaning of CBN sharpening stones
Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean with alcohol and toothbrush.
Maintenance (in 1-2 years), flattening/revitalization:
- resin bond stones - with silicon (silica) carbide powders on glass plate,
- metal bond stones - with FeCl.
There are other methods (with SiC powders..), but method with FeCl, on glass plate is the cheapest and simplest.
