Trying to get an Ra 32 finish without grinding...
A 32 finish is a nice finish, but does not require grinding. I personally would think a 16 would. If you are turning with a decent nose radius and a fine feed, providing your machine is not imparting any glitches[like if you were using the compound manually with no finesse, you should meet a 32 with at most a quick hit with fine emer
Different Methods to Finish Metal Surfaces | Fishbowl Blog
