Stainless steel polishing dilemma
++++
I have purchased multiple stainless steel parts that I need to
assemble for a medical device. These parts range in size from 21 x
2.5 x 0.25 inch to 12 x 7 x 8 inch to 5 x 1.5 x 0.75 inch. I am
welding this device together so that it's final dimensions will be 24
x 24 x 8 inch. My question is what would be the most cost effective
to clean up this raw T304 stainless to make it shine and look
professional - example - clean then weld, weld then clean and how
should i clean (tumbler vs chemical etc...). please advise

You say this is a medical device; therefore, it sounds as if
smoothness is the most important factor and the best way to
accomplish that is via a mecanical process. If the part does not
require a 6 to 12 RMS, then there are alternatives that are less
expensive.

You can try finishing it in a centrifugal finishing machine
wherein the mirror finish you require can be easily obtained in 2-3
steps depending upon the input samples.
