Material Finishing Machines Ebay

The 2000-Series machines are made with heavy production requirements. They are designed to handle such applications as deburring, slag grinding, calibrating/dimensioning, edge radiusing, paint/surface preparation, finishing/polishing or a combination of these applications.

A centrifugal barrel tumbling machine works on the same principle as a Ferris-wheel, but has smaller baskets that are attached to the edges. The centrifugal finishing machine or harperizing systems has 4 barrels. Each one represents a seat in a Ferris wheel. One large flywheel is also included. Each revolution of this flywheel produces one complete rotation for each barrel. The flywheel rotates quickly and produces extremely high centrifugal pressures, up to 15 to 20 times greater than the force of gravity. Under high pressure, the contents slide against each other. The increased pressure allows fast processing of metal parts as well as consistent and smooth finishes.

Centrifugal barrel tumbling machines are the fastest and most cost-effective method for deburring and/or polishing large quantities of metal parts at once. Also known as an industrial tumbler, rotary tumbler or harperizer system, a centrifugal barrel finishing machine uses a cyclical sliding action to grind the metal surface. Centrifugal barrel finishing is a type of mass finishing.

For removing significant burrs or blending lines caused by machining, centrifugal barrel-tumbling machines are well-suited. They are excellent in polishing, burnishing, and other applications. The centrifugal bar machines can work with a variety of organic and ceramic media, including corn-cob, to achieve any type of part finish, from extremely fine surface polishing to burr elimination.
