We have some stainless parts that we are trying to achieve an under 20RA finish on. Right now the process is 100% hand work. These are welded assemblies that we then take down the welds and work down to the finish with several steps of speedlock and 3M grinder wheels.
I would think this is possible with the use of a several step vibratory tumbler process with specific media (plastic media final step?). We already have several tumblers with large triangular stones currently used for heavy edge break, so I would hope we could just swap out media. We went to a local company that offers vibratory tumbling services and media to try to come up with a process, but the best results they got, using a 3 step (3 different media type) process that took over 8 hours, was high 20- low 30RA with a dull finish. I'd like a second opinion on this. I've seen pictures on here of absolutely gleaming polished looking parts coming straight out of tumblers! Is what I am asking impossible for our application?
Thanks!
