Centrifugal Barrel Finishing Machine Introduction

Centrifugal barrel finishing machines are one of the most cost-effective and high-gravity-performance tumbling machines out there. A typical centrifugal finishing machine operates on the Ferris wheel principle. Usually, four barrels are mounted at the periphery of the center turret. When the tumbling machine starts, one full turn of the turret wheel results in one complete rotation of each barrel.

You can fill each barrel to about 60%–80% of their capacity with a mixture of workpieces, media, compound, and water. You can use various types of ceramic tumbling media and plastic tumbling media. As the central turret spins, it generates a centrifugal force on the tumbling media and workpieces inside each barrel.



The centrifugal force causes the workpieces and media to rub against each other, resulting in the desired finish. Compared to conventional vibratory and barrel tumbling, this process is quicker and more effective. It is also ideal for parts with holes and recesses. The parts are also less likely to impact each other, making it suitable for polishing high-value surgical components, turbine blades, and 3D printed parts.
