Which tumblers are the best [Texas] 

Doesn't the regular tumbler have the same results as a magnetic tumbler? Which tumbler is the better one? Are there different reasons to use either one or one or both be used for all uses? I'm confused and need to know so I make the right purchase.

Thank you!

All mass finishing systems are different and used for different purposes. You speak of only 2 systems. There are 3 generations of equipment, barrel, vibratory, centrifugal. I can go into a lot of detail on each system; however, I think your decision should be based upon what do you want to accomplish. Generally speaking, if you have a low volume of parts and you have either castings or mill steel, then you want to improve the surface finish to get an even thin protective coating. If the parts are painted or get a thick coating, then requirements and options are greater. Your surface finish is more dependent on the media you use. Use ceramic preforms for hard ferous metals and plastics for soft non-ferous. Steel or porcelain is not abrasive and is used for fine mirror finish asthetics, they will not improve surface RMS. Unfortunately my book on this subject won't be out until late this year
