Vibratory rock tumblers

Compare documented stone-finishing machines by bowl size, voltage and approved media. Pick the bowl and abrasives together: the finishing routine depends on the machine as much as it depends on the grade printed on the grit packet.

What to check

Choose the motion for the job

A rotating drum lets the batch roll together. Choose a rotary machine when the goal is to round rough edges over the early stages. For a vibratory model, check what its manual says about the starting shape and the approved abrasive grades before committing to the same process.

Read the working load

Check the manual for whether the listed capacity includes both stones and media. Compare the usable load per drum or bowl before deciding that a two-drum machine handles larger individual stones.

Questions before buying

Can I use the same ceramic filler in a TV-5 and a TV-10?

Raytech’s shared instructions describe a separate TV-5 allowance and exclude ceramic from TV-10, but its current TV-10 with drain page allows ceramic. Verify the instructions for your exact model and revision before choosing this filler.

Can a ten-inch bowl hold twice the stone weight of an eight-inch bowl?

Use the manufacturer’s working-load specifications. Raytech describes about four pounds total for the TV-5 and about eight for the TV-10, including the workpieces and media.

When is a second bowl useful?

A separate bowl for finishing helps keep coarse residue out of polish. If you reuse the same bowl, clean it thoroughly according to the manual between stages.
