At the Virginia Symposium today, I had a couple of minutes to stop by Ken Rizza's booth, and he had me grind a gouge on a 600 grit CBN wheel. Nice polished grind for sure, but the burr is so fragile that I could just brush my thumb against the edge and the burr would brush right away off the edge.
Just my own personal thinking on this, but that seems to be too fragile an edge for most wood turning. Perhaps getting that fine a grind for a light finishing cut would be advantageous, but I am not sure if it would improve all that much over a grind from 180 or 220 grit. Several turners in our club upgraded to CBN today.....I think they will regret not having done it sooner! Ken also had a good deal on some of the new Rikon Slow Speed Grinders, and CBN as a package.....forget what the sign said, as I noticed it, but had people talking to me at the same moment.
