The VC & VC8 Series machines are equipped with 4 barrels spaced evenly on a heavy duty turret. As the turret is rotated in one direction, the barrels rotate to opposite direction effecting a 1:1 ratio. When the turret speed exceeds 60 RPM  the mass in the barrel is subjected to high compressive forces causing the work mass to slide to the furthest wall of the barrel. The energy created in this process produces finishes up to thirty(30) times faster than conventional methods such as tumbling barrels and vibratory mills.
