MODUMILL IE is the Fives flexible-precision answer for medium and large workpieces: a modular heavy gantry milling machine whose thermal stability, optimised damping and precision retention lead the specification. The Forest-Liné line from Fives Machining Systems puts every major configuration on the menu - moving table or moving gantry, fixed or moving crossrail, multiple independent work zones for pendulum machining, and rotary tables integrated into the platform for mill-turn flexibility.

Fixed crossrail or moving crossrail?

Fixed crossrails maximise rigidity for stable part heights; moving crossrails adapt to tall castings and deep moulds without re-fixturing. Because MODUMILL is modular by design - the first machine of its class, per Fives literature, to cover 40 to 60 kW S1 in one modular platform - the choice is a configuration decision, not a different machine. The spindle delivers 60 kW and 2,500 Nm at S1, the automatic attachment head changer keeps 3+2 five-face and 5-axis machining continuous, and the CNC runs Siemens 840D sl or Heidenhain.

Pendulum machining: what does it actually save?

Two work zones mean the head cuts on one side while the operator unloads the other, driving spindle utilisation toward the theoretical maximum without buying a second machine. For the sectors Fives names - aerospace, agriculture and construction, defence, oil and gas, rail and shipbuilding - that utilisation gain separates a gantry that pays for itself from one that waits. Against aerospace portal specialists such as Breton, MODUMILL IE competes on modularity and the head-changing automation; against repurposed boring mills, it competes on precision retention across long production runs, which is the property the thermal design exists to protect.
