The glass-aluminum curtain wall has become the hallmark of modern high-rise architecture. Skyscrapers, office towers, shopping malls, and airports rely on this façade technology to combine aesthetic design, energy efficiency, and durability.
However, to assemble thousands of aluminum profiles and glass elements with millimeter precision, CNC machining machines are essential. They ensure maximum productivity and repeatable quality for façade production.
Producing a glass-aluminum curtain wall involves numerous machining steps that cannot be efficiently or consistently performed manually.
CNC machining machines provide:
automated precision machining
integration with CAD and BIM data
fast changeovers for different profile geometries
consistent quality across thousands of profiles
A CNC machining center combines all major processes into one machine:
Sawing and cutting – precise length cuts and miters for frames and substructures.
Drilling – through-holes, countersinking, and threading for screws, rivets, and anchors.
Milling – pockets, slots, and contours for seals, fittings, and connections.
Grooving and slotting – recesses for cables, ventilation, or sun-shading systems.
Engraving and marking – serial numbers, logos, or building-level identifiers for on-site assembly.
CNC axes achieve tolerances in the hundredth-of-a-millimeter range – essential for seamless large façades.
Multiple operations are completed in a single cycle – ideal for mass curtain wall production.
Whether standard or custom profiles, CNC machines adapt to any façade geometry.
Sawing, cutting, drilling, milling, grooving, slotting, engraving, and marking are automated, minimizing labor and errors.
Direct connection with CAD/CAM and BIM architectural models ensures digital-to-production efficiency.
Skyscrapers – curtain walls with glass panels and aluminum frames.
Office buildings – glass-aluminum curtain walls with thermal efficiency.
Shopping malls – large curtain walls combining design and function.
Airports and hotels – representative façades with durability and energy savings.
Sawing and cutting – profiles are cut precisely to length, often with miters.
Drilling – holes for screws, anchors, and connectors.
Milling – slots and pockets for fittings, brackets, and seals.
Slotting – openings for cables or ventilation systems.
Engraving and marking – every profile is marked with a code or ID for installation.
