Centrifugal Disc Finishers

In order to help manufacturers increase throughput, decrease cost, and the increase quality of metal parts, Bel Air has developed their Centrifugal disc Finishers. These machines are designed to both polish and deburr a wide range of materials including brass, copper, steel, stainless steel, aluminum, kovar, titanium, and many more. They have been proven effective by eliminating 80% of handwork and producing over five times the output of normal, hand deburring operations! They have also been able to drastically reduce surface RA in metal parts across aerospace, automotive, medical, and other industries as well.

The Centrifugal Disc Finisher comes in sizes ranging from 4 to 60 liters and most models come with a mobile frame, ideal for cellular & JIT production. A wide variety of additional features are also available including integrated ultrasonic cleaners, on board media storage, a direct compound feed system, and parts separation options.

The Centrifugal Disc Finisher works by using a bowl-shaped finishing chamber, comprised of both a fixed upper bowl and spinning bottom disc. The rotation of the disc rotates both the media and parts within the chamber, forcing the mass to the stationary outside wall. Then this mass of part(s) & media folds back to the center. This process is repeated creating a three-dimensional, toroidal action similar to a vibratory bowl finisher. However, this action is tighter and produces ten times the G force of a vibratory bowl finisher. While this is happening water and finishing compounds are added into the mix to keep the media and parts clean.

 Unlike more traditional disc finishers, Bel Air models have a North/South gap allowing for the easy adjustment of the gap system. Process effluent, which contains the broken down parts of media, small amounts of part materials, and water mixed with compounds; flow through the gap, wearing it down. Bel Air’s adjustable gap system allows the gap to be closed as it wears down extending the machines service life.

To help assist manufacturers, Bel Air is available over the phone, online, or at our North Kingstown facility.
