High energy centrifugal barrel finishing machines also known as harperizer systems are the fastest and most cost-effective method for deburring and/or polishing mass parts or individual parts.

Finishing Machine
A centrifugal finishing machine / harperizing works on a principle similar to a ferris wheel meaning there are 4 barrels which would represent the seats on a ferris wheel and one large fly wheel. In 1 revolution of the fly wheel results in 1 complete rotation of each barrel.
Extremely high centrifugal forces can be generated on parts with this method. Using barrel finishing machines in combination with various types of ceramic and organic corn cob media, virtually any part finish is achieved by this machine — from surface finish polishing at an extremely high level to burr removal.
