Product Information

The RigiMill MG has achieved a chip removal rate of 1,000 cubic inches (16.4 liters) per minute in aerospace aluminum and is available with an automatic pallet system up to 950″ (24 m)!

RigiMill Moving Gantry (MG) was developed to produce the fastest chip removal rates in the world. Various spindle configurations achieve chip removal rates up to 55 cubic inches/min (0.9 liter/min) in titanium and 1,000 cubic inches/min (16.4 liters/min) in aluminum, this machine makes it possible to use the same machine for high speed roughing and finishing. Equipped with a single spindle, high speed gantry, the RigiMill MG provides the highest quality and precision for machining either aluminum or hard metals.

It is the unique architecture, as the most compact ever gantry structure with monobloc heavy cast iron bridge structure, as well as, its “no Ram” design through vertical moving cross-rail that offers the most rigid spindle thanks to constant overhang feature, and make the RigiMill MG as being a formidable “beast of efficiency”.

The RigiMill MG purposely reduced scale is an innovative design solution that offers new achievable performances compared to existing machines in the market. It can be configured to each customer’s specific needs and can be extended in the X-axis direction after installation. RigiMill MG is the best manufacturing platform in the world for long part production machining!
