What's the optimum SFM for finishing work? I've recently finished my slow grinder for finishing, and I think I slowed it down too much. What range should I be shooting for?

Depends if your hollow grinding or flat grinding,i think most will grind at different speeds suiting there own requirements so i think you will get a lot of different replys,myself i will usually do most of my hollow grinding at 3000 fpm using a 12 inch wheel, and about 500fpm using a small wheel attachment. Some finishing flat grinding real slow 50fpm. Hope you get more replys..

I'm a wide open kind of guy I guess.
I have V/S machines, but I run full speed most of the time.
( about 3500fpm I think I read)
I have one with step pulleys, but don't mess with them.
Wish I could help you more.
