Help, mirror finishing titanium in tumblers [Argentina] 

+++

Hello,

I'm looking some information about titanium polishing. We tried with the electropolish but it´s very slow for many pieces. And it's too toxic. I need information about polishing with media in tumbler or something.

Thanks,

Hmmm. Tough application problem. Most hard metals require a multiple step process using preformed shaped abrasive media with different compositions. You are talking at least a 2 step process and maybe a 5 step process (3 is common). If you are dealing with flat parts mass finishing is not the way to go. Recently we have gotten some very successful and interesting results using exotic combinations of inorganic and an organic mix.

There is great deal of surface finishing for reflective surface effects performed across the medical, aerospace and jewelry industries within centrifugal barrel finishing equipment. 2-3 steps with successively finer abrasive materials are used within time cycles of 30-90 minutes for each step.
