5-Axis Gantry Machining Center for Curtain Wall

Manufactured by Lebulang Machine at its Jinan, China factory — in operation since 1996 — the 5-Axis Gantry Machining Center for Curtain Wall holds CE and ISO 9001 certification and is supplied factory-direct with OEM/ODM support. This moving‑gantry 5‑axis CNC center processes long aluminum curtain‑wall profiles in a single clamping, performing milling, drilling, sawing and tapping on multiple faces. A high‑speed HSD spindle (12 kW or 15 kW, up to 18 000 rpm) and a 12‑tool magazine plus a dedicated saw‑blade station (max 400 mm) enable automatic tool changes. The Siemens 828D or OSAI 5‑axis control provides RTCP, pendulum machining and automatic tool measurement. Standard X‑axis travel is 6 500 mm, extensible to 9 400 mm.

Key Features

• 5‑axis simultaneous machining: X, Y, Z, A and C axes work together under RTCP to keep the tool tip accurately on path. One setup reaches five faces and the profile end, eliminating refixturing.
• Long‑profile capacity: X‑axis travel up to 6 500 mm as standard (7 000 mm or 9 400 mm optional) handles full‑length curtain‑wall extrusions without repositioning.
• Integrated sawing and milling: A tool magazine with 12 positions and an adjacent saw‑blade station (Φ400 mm) switches automatically between end mills, drills, taps and a circular saw for cutting‑to‑length and notching within one program.
• HSD spindle: 12 kW or 15 kW air‑cooled motor delivers speeds from 0 to 18 000 rpm, suitable for aluminum alloys and thin‑wall steel profiles.
• Precision and repeatability: Linear guides and servo‑driven ball screws give ±0.01 mm positioning and ±0.005 mm repeatability, meeting the tight joint tolerances required in unitized curtain walls.
• Pendulum operation: The control supports pendulum mode — machining one workpiece while the operator loads another on a separate fixture zone, reducing idle time.

Technical Specifications

How It Works

The 5-Axis Gantry Machining Center for Curtain Wall operates with a moving gantry over a fixed worktable. The operator places the aluminum extrusion on the table and activates the pneumatic or hydraulic clamping. A pre‑written G‑code program is loaded through the Siemens or OSAI control. The gantry moves along the X axis to the first machining position, and the 5‑axis head delivers the spindle to the required angle. RTCP automatically compensates for tool‑length offsets during rotary movements, so the tool tip follows the programmed path accurately. Operations such as drilling, milling, tapping and sawing are performed on multiple faces without unclamping the profile. When a machining sequence finishes at one zone, the gantry travels to the next, or the machine enters pendulum mode, allowing the operator to unload a finished part and load a new one while machining continues on the adjacent fixture. Chips are removed by an integrated conveyor.

Main Application Scope

Typical applications for the 5-Axis Gantry Machining Center for Curtain Wall include:

1. High‑rise building unitized aluminum curtain wall frames
2. Hidden‑frame and exposed‑frame glass facade extrusions
3. Curtain wall corner joints and special‑shaped facade profiles
4. Sunroom, skylight, and large aluminum window and door profiles
5. Point‑supported glass curtain wall aluminum support brackets
6. Industrial aluminum facade and decorative steel wall profiles
7. Aerospace lightweight aluminum profiles (cross‑industry compatible)

Suitable raw materials: 6063 aluminum alloy, hollow extrusions, solid aluminum, thin‑wall steel, PVC architectural profiles.
