Default Re: Vibratory Tumbling

I don’t think you can achieve a mirror finish or even get close in a tumbler.
It’s good for de-burring and will leave a uniform finish suitable for industrial anodizing, paint, or powder coat. I don’t like polishing parts that have been tumbled and I hate it when they have been blasted with sand or any other media.
I find that tumbled parts get micro pits from electrolysis and require more sanding.
I also notice it is harder to clean / degrease the areas that don’t get sanded and polished.
Not that I am an expert on tumbling, but I have operated them and had to polish plenty of tumbled parts from several different sources and the results have always been much the same with the occasional “these parts are ruined” thrown in.
