do all rock tumbling machines need refills?
I want to invest in a rock tumbling/polishing machine but I can't figure out if they all need to have refills for the process that I have to buy. Are there any that don't take any?

They all need refills eventually.
Just as the rocks you’re polishing get smooth by abrasion, the abrasive gets smooth by knocking against other abrasive particles.
The lost material is carried off in the slurry water.
Eventually the abrasive particles are themselves too polished to be of use and need to be replaced.
