Cincinnati U6 bridge-type

Product description

The Cincinnati U6 series adjustable-crossrail portal mill raises the bar for five-sided, oversize-part machining. An adjustable crossrail and robust design allow for extra-large part processing with minimal ram extension and heavy-duty cutting performance, making it ideal for machining forgings, castings, or large weldments of cast iron, steel, or titanium. 

The Cincinnati U6 series is available in moveable-table (bridge-type) and moveable gantry (rail-type) platforms. The machine’s modular design accommodates a wide range of part size and shape requirements for aerospace, agriculture, construction, mining, power generation, energy, industrial equipment, marine, rail, and mining equipment.
