My CBN system (using half-speed grinder and Tormek guides) replaced a Tormek, which was subsequently sold.
In contrast to Adam, I view the Tormek as a grinder, but a poor system for the experienced user. Great for a beginner. The CBN makes it outdated.
The ideal system now would be a 180 grit CBN wheel on a 8” half-speed grinder, with a half-stitched white mop on the other side (for the Unicorn profile).

They now sell CBN wheels sized for the Tormek machine.

That is just so silly. The reason for the Tormek was to avoid burning a blade. And so they made it run slow and wet. CBN becomes popular for bench grinders, and Tormek attempt to counter the challenge by introducing diamond wheels. Now you do not need the water to cool the steel. But they still cut soooo sloooow. CBN is offered as an alternative to diamond. That does not improve matters.
