Gantry Machining Centres

Three builds. LM runs linear rails for faster traverse, LMB runs four hard rails and a square ram for heavy transverse cutting, and the DLM moving column is set up for high-speed aluminium work.

Gantry machining centres

Double-column gantries from 2 m to 8.5 m X travel, with table loads to 40 t. LM runs linear rails for faster traverse, LMB runs four hard rails and a square ram for heavy transverse cutting, and the DLM moving-column build is set up for high-speed aluminium work.

Choosing A Lathe

Bed Type Follows The Part

Sixty models is a lot to read through. Send the part instead: the largest diameter, the length, the material and the tolerance, and we will name the two or three that fit and say why.

  1. Flat bed for weight

    A wide flat bed carries heavy, long work and damps the cut. It is the right choice for shafts, rolls and anything needing a steady rest, and it is easier to load with a crane.

  2. Slant bed for chips and speed

    Chips fall into the conveyor instead of piling on the ways, and the turret sits closer to the spindle centreline. Best for repeat production of medium parts.

  3. Vertical for diameter

    Once the part is heavier than it is long, gravity works with you rather than against you. Flanges, rings, wheels and gearbox cases belong on a table, not between centres.

  4. Y-axis when it saves a setup

    A power turret and a C-axis pay for themselves the moment the part would otherwise move to a machining centre for a keyway, a flat or a cross hole.

Every model page carries the specification we hold on file. Foundation drawings and ISO 230-2 acceptance figures come with the quotation.

Buying FAQs

Gantry Machining Centres Questions, Answered

When does a part genuinely need a gantry machining centre?

When it outgrows every table — machine beds, frames, rails, long aluminium structures. These gantries run 2 m to 8.5 m in X with the bridge carrying the spindle over the work, so the part stays put and the accuracy problem stays manageable.

How much weight can the gantry tables carry?

Table loads to 40 t across the group. At that scale the question shifts from "will it fit" to "will it sit still": levelling, foundation and support points get engineered with the machine, and we state the requirements with the quotation rather than after delivery.

Why does a one-piece bed casting matter on a 6 m gantry?

Because every joint in a bed is a place for geometry to move. Beds here are cast in one piece up to 6 m — cast, aged in the yard, then machined — so the straightness the laser measures at acceptance is the straightness the machine keeps, not a bolted approximation of it.

What foundation does a gantry centre need?

A dedicated reinforced foundation sized to the machine and the soil, with the plan supplied as part of the contract. It is the one part of the installation you cannot fix afterwards, so it is engineered first — pit drawings, anchor layout and curing time are all stated before the machine ships.
