HZ High Energy SeriesThe HZ Series Finishing Machines are the most economical, high speed finishing equipment available. The variable frequency speed control permits fine finishing and polishing at slower speeds and aggressive deburring and edge radiusing at higher speeds. Four barrels are mounted at the periphery of a large turret. Each barrel is loaded with media, parts and water to approximately 50% to 90% full.

Model HZ-12 & Model HZ-40During operation, rotation of the large turret creates a centrifugal force on the media and parts inside each barrel. This force compacts the load into a tight mass causing the media and parts to slide against each other, Model HZ-120removing burrs and creating superior finishes. This action also reduces the cycle time needed to complete the finishing of the parts by up to a factor of 30 over conventional vibratory and barrel tumbling. Hand finishing operations can now be efficiently and economically automated with the HZ series machines. Results with this centrifugal barrel finishing equipment are consistent and predictable, every time.

HZ High Energy SeriesThere are nine models to choose from in the HZ series. The HZ-12, HZ-30 2S and HZ-40 all have removable barrels. By utilizing an extra set of barrels, the operator can unload and reload one set while the other set of barrels is in cycle in the machine. Our models are supplied with removable liners as standard equipment. This feature decreases downtime and lowers maintenance cost. The HZ-80 and larger have the ability to use dividers to eliminate part on part impingement.

Automatic Parts Separator - PSA Series

Designed to work with the HZ Series Centrifugal Barrel Finishing Equipment Systems, this Automatic Parts Separator is the perfect way to unload the barrels and separate your parts from the media. Simply position the barrel over the vibrating screen deck and “dump” the media and parts out. Your parts stay on top of the screen, while the media falls through to the bottom catch pans.
