i series CNC-turning machines


iTwin S – machining from all sides

Equipped with altogether 29 tools the iTwin S can machine complex parts from outside, inside and the outline. The opposed spindle allows machining from the rear side in simply one clamping. 12 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.
