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 finishing requires the use of the right tumbling media. The cycle time for parts can be doubled if the media is not right, especially if it's the wrong geometry. If you are not using cones or cylinders to tumble media, it can significantly slow down the processing time.

A grinding wheel can be described as a disc or cylindrical for cutting with abrasive or cutting action or sharpening cutting tools .
Centrifugal barrel tumblers are a specialized form of barrel tumblers in which centrifugal force adds to the effects of barrel tumbling.
Built in a heavy duty construction with a smaller footprint designed to accommodate a job shop with various applications such as deburring, dross removal, calibrating/dimensioning, edge radiusing or finishing.
One manufacturer of medical devices faced two challenges when it came to designing a citric solution for passivation. This prevented them from using a fully automated passivation process. To ensure quality control, the system must have data tracking. Semi-Automated [...]
Every Triumph trimmer comes with either stationary or mobile transparent Lexan safety protection guards. All models are subject to independent safety testing and meet all applicable international safety regulations. Triumph trimmers are certified in accordance with a quality system that has been established in all areas of the company under DIN EN ISO 9001 :2008 standards.
To create sliding friction, barrel tumblers combine rotary motion with abrasive media. You can imagine putting rocks in a barrel and then rolling it downhill. As the parts slide against each other, the deburring and polishing takes place.
Mass finishing refers a group of manufacturing processes that can be applied to large quantities of pieces simultaneously. In mass finishing, metal parts that are not in use are placed in containers. This creates friction and causes the metal to rust. This friction can cause a cutting action, which can take many forms: from heavy grinding to fine Polishing.
Are you frustrated by flat parts Flat parts such washers pose the biggest challenge in centrifugal barrel finish. They can stick to or wick together on the barrel sides, so only one side is deburred. Add glass bead blasting media into the centrifugal-barrel finishing process. The beads coat parts so that they won't stick together or to the barrel. Glass beads are also great for parts that may be difficult to separate.
