KARGO
CYLINDRICAL GRINDING
HEAVY SHAFTS
EASILY GROUND
Up to six tons and several yards long – grinding shafts of this size is
a challenge that is tirelessly mastered by the grinding machines of
the Kargo series. A powerful clamping fixture, hydrostatic guides and
hydrostatically mounted grinding spindles guarantee the greatest
possible precision.
