Oh, wait a minute. Are you talking about using a single-point diamond to
dress diamond wheels on a surface grinder? That I've seen. I was thinking
about the wheels on a bench grinder. Can you dress them the same way?
Yes, of course, but your results will be as accurate as your hands are.
With a light touch so the low spots in the wheel don't "draw in" the
dresser, you can do pretty well. Mostly, I've used this to dress toolpost
grinder wheels on the lathe or
diamond wheels on the mill, but I have done it freehand a few times in
special cases.

What's the mechanism of action? Does it just sheer the diamond grit out of
the matrix, or does it fracture the particles of grit?
