I guess I’m the outlier.
Bought a pair of CBN wheels, several yrars back, due to all the positive comments in these threads.
Was disappointed with the finish. Also, was able to overheat a cutter if I tried (not magic).
Contacted the company, and they told me that I ‘just needed more practice with the grinder’.
Sold the wheels in the Trading Post.
Now, I have LOTS of vitrified wheels: several from the CBN converts who swear that they ‘will never use them again!’ (Thank you!).
They do produce more dust, so I grind outside if I can. I dress them lightly every loop, and can custom shape / profile them if I want.
And I can get 8, quality, vitrified wheels for the cost of one, cheap, CBN wheel: so cost effective?
There might be better ones out there, than the ones I tried.
