3kg / 5kg Rotary Jewelry Tumbler Polishing Machine

Rotary Tumbler for Consistent Jewelry & Gem Finishing

This 3kg / 5kg rotary tumbler surface polisher is designed for reliable, repeatable polishing and finishing of jewelry, gems, and small metal parts. Using a rotating drum and media such as steel or iron beads, it removes oxidation, smooths edges, and refines surfaces on items like rings, pendants, castings, coins, and small hardware. With a clear barrel and simple controls, it supports both workshop production and DIY jewelry projects that require controlled, uniform results.

The machine is available in two capacities-3kg and 5kg-so you can match the load size to your workflow. The polycarbonate barrel is formed in one piece for a leak‑resistant structure, and a locking bar/buckle system keeps the lid secure during operation. An upgraded gear transmission drives the drum more smoothly, reducing vibration and helping the load tumble evenly. The control panel offers bidirectional rotation, five speed levels, and a 10-60 minute timer, allowing you to set different cycles for rough cutting, deburring, cleaning, or final polishing depending on the material and media you use.

The tumbler supports a wide range of materials, including jewelry alloys, steel, iron, copper, zinc, aluminum, and magnesium alloys. It can be used for surface polishing, chamfering, trimming, rough finishing, precision finishing, removal of dark spots, and fine grinding. A non‑slip rubber base stabilizes the unit on the workbench and helps absorb operational noise and vibration. For small to medium batch work, multiple pieces can be processed in a single run, making this unit suitable for studios, repair benches, and home workshops that need consistent surface finishing without manual hand‑polishing.

Why It's a Smart Choice

• Adjustable speeds and timer support different stages of finishing, from rough cut to final polish.
• 3kg / 5kg capacity handles multiple pieces at once for efficient small to medium batch processing.
• Leak‑resistant barrel, secure closure, and stable rubber base support safe, continuous operation.

FAQ

Q: What materials can I polish in this tumbler?
A: It is suitable for jewelry alloys, gems (with appropriate media), and small parts made of steel, iron, copper, zinc, aluminum, and magnesium alloys. Always match the media and compound to the material and desired finish.

Q: How do I choose between the 3kg and 5kg versions?
A: Choose the 3kg model for smaller batches, limited space, or occasional use. Select the 5kg model if you process more pieces per cycle or run frequent polishing and finishing jobs.

Q: Can beginners use this machine?
A: Yes. The control panel with two‑way rotation, 5 speed settings, and a 10-60 minute timer is straightforward. Once you select suitable media and cycle times, the process is largely hands‑off.

Q: Does it only polish jewelry?
A: No. In addition to jewelry and gems, it can be used for cleaning and finishing small metal parts, coins, and other compatible items that fit in the drum and can safely be tumbled with media.
