CBN Wheels
The link below is good primer for CBN grinding. The most useful info for me is the chart that shows the grit equivalency between AO and CBN. I did a lot of reading when CBN started to become of interest to woodturners, but decided I couldn’t justify the expense with several AO wheels sitting on my shelves. Although CBN is gaining popularity in the woodturning community, it is not a new product as it has been used in the machining and industrial world for some time. Although I haven’t tried a wheel, the three main benefits I see are safety and consistency related: the elimination of grinding dust from the wheel itself, the elimination of the possibility of a wheel exploding, and a consistent wheel size.
