I have a baldor carbide grinder. It is rated at 3450 rpm with 6" wheels. I have a diamond wheel on one side and a silicon carbide on the other. It is a great machine for grinding. I think both of yours will work just great as a final finishing machine, something the baldor is not. After all, lots of folks including myself, use diamond hand laps for a final finish and I know my arm doesn't generate a high sfpm....
Darrell, that sort of validates the use of the (free and therefore desirable) 3000 RPM motor and 4 inch wheel that I have. Ulma Doctor's application, at least as I understand it, is fine finishing while my own usage sounds more like yours. I need to rough-shape carbide tools maybe refine with a green wheel but always hand-lapping with a diamond tool as the final step.
I've been roughing with the green wheel before lapping but it takes some time and throws off a lot of debris Thanks for your reply and I'm hoping that Ulma Doctor will also put in a word - I may have wrongly inferred how he's using his grinder.
