Polishing 303 stainless steel, 3/8 hex material
Hi, I am trying to mirror polish a 303 ss hex material. I am dealing with a very tight tolerance and customer need it to be 0.072
- 0.375" from side to side in Hex material. considering raw material tolerance we can only polish away 0.001" of material. my question is: is there any way we can mirror polish ss material with only taking material down by 0.001"?
Thank you so much

Theoretically yes. It would depend on the initial quality, tolerance and roughness of your raw material. Remember that a coarse finish for regular machining is around 125 RMS. That's 1/8th of a thou. A fine ground finish would be 32RMS (1/32nd of a thou) or even 16RMS (1/64th). A cold drawn barstock finish might be in between those values. Obviously, these numbers do not consider deep draw lines, inclusions, dings, corrosion, etc.Guillermo Marrufo

Need to know size of material. If it is smaller than a 12" cube, you can try mass finishing using a dry organic process.
