Assuming you're referring to a rock tumbler made by the Evans company, it is best to follow carefully the instructions that came with the machine. Tumble-polishing gemstones is a very simple and inexpensive, yet time consuming hobby. The drum is partially filled with stones, preferably of similar hardness, then water and grit is added. The drum is sealed and placed on the rollers, which spin it slowly. Time required depends on the hardness of the stone used. Several different grit stages are used, with finer and finer grit, followed by the polishing stage. Books have been written on the subject, and there are superb and comprehensive websites out there; rocktumblinghobby.com is highly recommended.

"Lapidary cutting equipment" would, I'd suggest, primarly mean diamond saws and now even lasers are being used. Lapidary grinding equipment would apply to a variety of machinery, from tumblers to cabochon machines to flat laps or faceting machines.
