TETRAD High-Speed Barreling Machine

High-speed barreling machine for dry tumbling of metal frames.

This machine consists of 4 barrels using centrifugal force to grind and polish all kinds of metal frames, and components (e.g. fronts, temples)
A mix of specially selected pastes and abrasives provides excellent surface quality and high gloss shine.

Thanks to carefully tested drive-mechanisms, this machine can reduce processing times by 50% when compared to traditional barreling systems.
Frames are fixed to metal supports (2 racks per barrel), which can be customised to customers’ needs.
