Centrifuge Finishing Machine

Centrifugal disc finishing machines spin a stationary-tub design at high speed, forcing media and parts outward and upward in a helical flow that finishes parts many times faster than vibratory systems. Short cycles of 5–15 minutes achieve heavy deburring, edge radiusing and mirror polishing.

The high-energy action makes centrifuge finishers the standard for removing machining marks from turned and milled parts, descaling after heat treatment, and producing pre-plate or mirror finishes on small-to-medium metal components such as gears, fittings, watch parts and medical implants.

Machines feature variable speed drives, polyurethane-lined bowls, automatic media separation and optional rinsing systems. Longyanxing supplies lab units for process development through to multi-bowl production lines. Send your drawings for a cycle-time estimate.

Frequently Asked Questions

How does a centrifugal disc finishing machine work?

Parts and media sit in a stationary bowl above a rotating disc. The disc spins the media bed outward and upward, creating a strong compressive force between parts and media. That high-energy action removes burrs and radii edges far faster than conventional vibratory finishing, often in a small fraction of the cycle time.

Why is centrifugal finishing faster than vibratory finishing?

Centrifugal machines accelerate the media bed to several times the force of a vibratory tub, and the disc keeps the whole bed moving uniformly. The result is a much higher cutting rate per minute, which is why centrifugal disc and barrel finishers are chosen when cycle time, throughput and floor space matter.

What parts are best suited to a centrifugal disc finisher?

It suits small and medium machined, stamped, cast and forged parts that need fast deburring and edge radiusing in high volume, including fasteners, hydraulic fittings, gears and jewellery. Very large or very light parts that cannot be carried by the media bed are better processed in a vibratory machine.
