Jumbo Diamond Polishing Motor

As the name suggests, this machine is used for polishing precious diamonds and gemstones.

• Single-Piece Spindle: The motor spindle is machined from a single piece, which significantly increases stability at 2880 RPM.
• Super-Precision Bearings: We use super-precision bearings to achieve 0.001 mm accuracy on the spindle, ensuring a long motor lifespan.
• High-Precision Grinding: The spindle is ground on a high-precision cylindrical grinding machine, delivering a run-out of just 0.001 mm on the bearing size and all scaife mounting surfaces.
• Dynamic Balancing: Finally, our spindle is dynamically balanced on a highly accurate balancing machine. This minimizes vibration and extends bearing life.
• Reasonable Pricing: High-quality engineering offered at a competitive price.

Any diamond can be polished on a Sizer Engineering diamond polishing ghanti (mill), whether it is CVD (lab-grown), a gemstone, or a natural diamond.

Sizer Engineering stands firmly behind the quality of our diamond polishing ghanti. If you are not completely satisfied with our product, we are ready to take it back within one week.
