tumble finishing for roundness

tumble finishing for roundness

tumble finishing for roundness

(OP)
I'm curious about anyone who has experience with LARGE tumbling operations.

We have a large volume (perhaps up to several tons a day) of oblong ceramic balls ~1.5 cm diameter that we would like to make more round, preferably marble roundness.  surface finish is not important as long as it isn't so bad, so chipped and rugged, that the ball isn't round.

Would vertical or horizontal axis tumbling with, say, SiC or other abrasive particles accomplish this reasonably efficiently.  Is there a better process for very large volumes?

I am looking for good sources about the details of the process: how much material will be removed inorder to accomplish roundness, how tumbling effects the surface strength, length of time required, effect of media hardness differential, etc.

thanks,

elliot

RE: tumble finishing for roundness

there is a vibratory finishing and polishing form -- that might be better
