i series CNC-turning machines


iTwin – machining from all sides

Equipped with altogether 26 tools the iTwin can machine complex parts from outside, inside and the outline. The opposed spindle allows machining from the rear side in simply one clamping. 9 live tools, 2 C axis as well as Y axis offer further flexibility. The machine is perfectly suitable for working from bar as well as for insert parts.
