Curtain Wall CNC Fabrication

Curtain Wall CNC Machining for Aluminum Extrusions

CNT-1000 Series Curtain Wall CNC Fabrication Machine with One Tilting Z-Head and 15″ X 36′ Work Envelope

The only Curtain Wall CNC machine for aluminum extrusions with vertical and horizontal clamp-down fixturing.

In 1999, CNT built the first of several machines designed to drill and mill long aluminum extrusions for pre-engineered commercial building exterior wall coverings, known as curtain walls. (This operation was previously being performed by individuals with drills and tape measures. The milling was done separately on a manual Bridgeport, requiring frequent indexing of the part.) Today, we’re offering a single-step, automated curtain wall CNC fabrication solution with a standard work envelope that’s even larger, a pivoting head, automatic tool changer and alcohol/oil coolant system.


This is also a perfect solution for machining aluminum extrusions for door and window frames.
