Dual-Spindle Bench Lathe Polisher | Jewelry Grinding and Polishing Machine
This 180W dual-spindle bench polisher is designed for jewellers and small-workshop finishers who want two surface-finishing stages ready at one station. Mount different wheels on the left and right tapered spindles to move directly from initial refinement to final polishing without changing accessories.
A front-mounted dial provides continuously adjustable speed from 0 to 7,000 RPM. Both spindles are driven by the same motor and rotate simultaneously at the selected speed. At 2.78 kg, the compact body fits jewellery benches and small studios without occupying a large footprint.

Pro Tips
- Confirm spindle dimensions and each wheel's rated speed before purchasing or mounting any accessory.
- Start at low speed after every wheel change and check for smooth, centred rotation before increasing RPM.
- Keep separate wheels for different compounds to avoid cross-contamination between finishing stages.
- Use light, controlled pressure — let the wheel and compound do the work rather than forcing the piece.
- Disconnect power and wait for both spindles to stop completely before cleaning or changing either wheel.
FAQ
Can the two spindles run independently at different speeds?
No. Both spindles are driven by the same motor and operate simultaneously at the same selected speed.
Which wheel sizes fit the spindles?
Spindle dimensions are not specified in the product information. Confirm compatibility with the seller before ordering wheels to ensure a correct fit.
Are polishing wheels or compounds included?
No polishing wheels, abrasives, or compounds are confirmed as included. Plan to source compatible accessories separately based on your material and required finish.
Which voltage version should I order?
Select the 110V or 220V version that matches your local mains supply. These are separate products — connecting to the wrong voltage will damage the machine.
Is this suitable for heavy industrial grinding?
No. The 180W motor is designed for jewellery and small-part finishing, not for large workpieces or heavy continuous grinding.
