Jewelry Magnetic Tumbler

What Is It?

A magnetic tumbler for jewelry is a benchtop device that uses a rotating magnetic field to drive stainless steel pins for surface treatment. The moving pins reach recesses, settings, and complex geometries that are difficult to access with other methods. This type of equipment is commonly applied after casting, soldering, or filing to support surface brightening on gold, silver, and stainless components.

What Should You Consider When Buying One?

When evaluating this type of jewelry magnetic tumbler, consider:
Capacity and Bowl Size: Match the volume to the size and quantity of parts being processed.
Speed and Program Options: Variable speed or programmed modes help adjust pin motion for delicate settings.
Pin Specifications: Diameter, length, and total weight influence contact behavior and should align with the alloys used.
Noise Level and Footprint: Review dimensions and bench placement requirements.

Application Scope

This equipment supports burnishing of chain links, settings, filigree elements, watch components, and small findings with narrow passages. It is often used before ultrasonic cleaning or after rotary tumbling as part of a multi-stage finishing workflow. The method also assists in removing light oxide and residual compounds from earlier processes.

Buying Considerations

Before selecting a magnetic tumbler jewelry polisher for workshop use, review electrical requirements, recommended pin weights, and bowl fill markings. Confirm compound guidance and any limitations related to plated items or set stones. Request documentation covering cleaning procedures, pin storage, and bowl care to reduce cross-contamination between different metals.
