Hello,
Centroid do an 4 axis controller for around $1500 that is upgradeable to 8 axis. So maybe double the original price. But, the dreaded import tax will take that price up.

I suppose buying one or not will depend on budgets and the reality of cost versus requirements.
But, that controller does seem to have all the bells and whistles.
Cheers

You could do it with 3 stepper axes .... or even two, and an adjustment for depth of cut on the wheel. Controllers are like $20 on Ebay.

I've been playing with an ANCA TG4, circa 1991 or so, for the past couple of months. It has 4 controllable axes: A for rotation, X is left/right, Y is near/far, and Z is up/down. Grinding spindle is mounted on Y-Z and has a manual rotation angle about the Z axis. A axis is mounted on X.
All together it makes for some interesting motion possibilities. I have electronic copies of the manuals if they'd be of any help to you.

Trying to get my head about the axis...Is it like this, but grinding spindle is doing Y?
This looks pretty compact, and workpiece is easy to reach, but cartesians are all stacked:
