Twin Five-Axis Gantry Machining Center

GA-FMB3020DTwin Five-Axis Gantry Machining Center

A twin five-axis gantry built around a single idea: clamp a large integrated die-cast structural part once, and machine all six faces without ever turning it over.

What we advertise is what we are willing to sign.
The specifications below are published exactly as they appear in the technical agreement — not as they appear in a brochure.

Why this machine

Three things this model does better than the alternatives — and the numbers behind each of them.

01
6 faces, 1 setup

Every re-clamp is an error you cannot machine out

A large die-casting that is turned over four times collects four location errors and four blocks of handling time. Two synchronised five-axis heads on one gantry remove those steps. Reported machining efficiency gain: 25%.

02
World No. 3

Shipment volume, not just a trophy

Third globally for twin five-axis gantry machining center shipments in 2024. An award proves a panel of judges was convinced; a shipment ranking proves the market was.

03
2 × 5 axes

A gantry designed in simulation before it was cast

Three axes driven by high-thrust linear motors in synchronisation, on a viaduct-type gantry frame optimised through CAE static and dynamic stiffness analysis and thermal simulation. Winner of the Gold Medal at the 2024 Geneva International Exhibition of Inventions.

Typical applications

Where this model earns its place on the shop floor.

NEV integrated die-cast rear floor

The part that replaced dozens of stamped and welded components. It still has to be machined on every face, and every re-clamp puts the accumulated tolerance at risk.

Front cabin and shock tower castings

Large, awkward geometry with machined interfaces on multiple planes — exactly the case where twin synchronised heads halve the spindle time.

Battery enclosures and trays

Long sealing faces and dense hole patterns across a 2,700 × 1,900 mm envelope, machined in one clamping to protect flatness across the whole sealing plane.
