Large Aluminum Plate & Gantry Machining: Complete Guide

What is Aluminum Plate & Gantry Machining?

Gantry machining uses a large bridge-type machine whose spindle travels over a wide table, allowing one-setup milling of large-format aluminum plates. We machine base, fixture, tooling, cooling and structural plates with controlled flatness and parallelism.

Large-format capacity

Gantry centres handle oversized plates that do not fit on standard vertical machines, milling, drilling and tapping the full surface in a single setup.

Flatness and parallelism

Large plates are prone to distortion, so we control fixturing, tooling and stock treatment to hold flatness and parallelism critical for linear rails and precision assemblies.

Cooling and vacuum plates

We machine liquid cooling plates with sealed channels, vacuum chuck plates and optical breadboards with dense hole grids, where consistent depth and leak-tight performance are essential.

Frequently asked questions

How large a plate can you machine?

Our gantry centres accept large-format aluminum plate; send your dimensions and we confirm capacity and fixturing during DFM.

How do you control plate flatness?

Through stock selection, stress-relieved material, careful fixturing and balanced machining, with flatness measured on final inspection.

Can you make liquid cooling plates?

Yes — including channel design, machining and sealing, with pressure/leak testing before delivery.

What finishes are available for plates?

Clear or coloured anodising, hard anodising, bead blasting, brushing and chromate conversion, with masking where needed.
