High-Speed Barreling Machine TETRAD for dry tumbling of metal frames

This machine consists of 4 barrels using centrifugal force to grind and polish all kinds of metal frames. A mix of pastes and abrasives provides excellent surface quality. Thanks to carefully tested drive-mechanisms, this machine can further reduce processing times compared to traditional barreling systems:
Grinding:         4 – 5 h instead of 12 h
Polishing:        3 – 4 h instead of 8 h
