Key Features & Benefits

The CJG480 is a fundamentally different machine from standard rotary barrel tumblers. Where a standard DM barrel tumbles parts freely with media, the CJG480 uses hangers — parts are hung individually from fixtures mounted inside the rotating bamboo barrel. Parts never contact each other or the barrel wall directly. This hanger design is the defining reason to choose the CJG480 over any other barrel finishing machine.

⚡

Hanger Design — Parts Hung, Not Tumbled

The CJG480 can hold up to 480 parts simultaneously on 8 hangers inside the rotating bamboo drum. Each part is fixed to a hanger arm; as the drum rotates, the hangers orbit through the media (walnut shell or organic media + polishing paste) without the parts touching each other or the barrel wall. This eliminates all part-on-part collision marks — the failure mode that makes standard barrel tumbling unsuitable for high-value parts like silver jewelry, medical implants and titanium eyeglass frames. The hanger and drum rotate independently (drum 0–50 rpm, hanger 0–80 rpm), creating compound motion that covers all part surfaces.

  • Parts hung on fixtures — zero part-on-part contact throughout the entire cycle
  • Up to 480 parts per batch on 8 hangers — high throughput without collision risk
  • Independent drum and hanger rotation — compound motion covers all part surfaces uniformly
⚡

Dense Bamboo Drum — Eco-Friendly, Long Service Life

The barrel is constructed from dense bamboo rather than metal or PU-lined steel. Bamboo provides natural cushioning for the organic media (walnut shell, olive shell) used in polishing, absorbs vibration to reduce noise during the cycle, and is significantly more durable than standard wood barrels for this application. The bamboo construction is also why this machine is described as eco-friendly — no PU casting, no synthetic lining replacement cycles. The barrel material is well-matched to the dry organic media polishing process it was designed for.

  • Dense bamboo barrel — natural cushioning for organic media; lower noise than metal-lined alternatives
  • No PU lining to replace — bamboo construction reduces ongoing maintenance material cost
  • Suitable for walnut shell, olive shell and other organic media + polishing paste combinations
⚡

Siemens PLC, Fast Loading, PLC Touch Screen

The CJG480 uses a Siemens PLC touch screen controller with up to 50 programmable recipes — each recipe stores drum speed, hanger speed and cycle time for a specific part type and polishing target. Fast loading design: parts clip onto hanger arms and the loading sequence for a full 480-part batch takes minutes. An optional Bosch Rexroth VFD provides fine speed adjustment for both drum and hanger rotation without changing hardware.

  • Siemens PLC touch screen — up to 50 stored recipes; one-button start for repeat production
  • Fast loading design — clip-on hanger arms; 480-part batch loaded in minutes
  • Optional Bosch Rexroth VFD — fine drum and hanger speed adjustment without hardware changes

Product Overview

The big rotary barrel finishing machine is an eco-friendly solution, designed mainly for polishing small, high-value parts (such as jewelry) to achieve a flawless shine.

It operates on the same principle as standard rotary barrel finishers, with a wooden or bamboo barrel for gentle processing. For polishing, we recommend walnut shell grit or olive-shell media, which help remove surface impurities while protecting delicate parts.

Operation Tips

  • Hang the parts inside the barrel.

  • Set the processing speed and time.

  • Start/stop the machine with a single button.

Fine Grinding / Polishing

  • Simple operation with stable, repeatable results.

  • Adjust the cycle time to achieve the required smooth, glossy finish.
