It should not be confused with satellite centrifuge rotating bottomed centrifuge; centrifugal barrel has the great advantage of not having a rotary sealing, often so difficult to maintain and adjust. Magnetic centrifuge meanwhile has been developed for complex applications related to a need for polishing or deburring of hollow parts; With this equipment, the very special chips movement allows to deburr the inner areas of parts, such as bores or threads. This equipment will be presented on the Industry show in Lyon as a technological innovation.
