Thread: Jnat finishing

The first day I had it I got my tomo stuck. It was an insane amount of suction and I was lucky to get it off! I grooved the tomo after that and keep any eye out for any suction building.

Yeah, the Atoma 1200 works fine because of the pimpled surface, but I wouldn't even think of using a DMT 1200 on a hard natural. The one time I tried years ago, it scratched the stone & also pulled a lot of zinc off the plate. Never again.

There was a thread about this in the past & DMT themselves say nothing finer than the 325 for lapping.
Of course slurry generating may be less of an issue.
