CNT-1000 Extrusion Series CNC Machine with One Tilting Z-head 4' X 12' Work Envelope

In 1999, CNT built the first of several machines designed to drill and mill aluminum extrusions for a variety of applications, including door & window frames, aircraft components, lighting enclosures and wall systems. (These operations had typically been performed by individuals with drills and tape measures. The milling was done separately on a Bridgeport with limited table travel, requiring frequent indexing of the part.) With a 12-foot bed, 24 vise clamp positions, eight pop-up position stops, pivoting head, 16-position automatic tool changer and alcohol coolant system, the CNT machine provides a single-step automated solution. On the machine pictured here, the vise deck is removable to allow access to a fully functional vacuum grid bed for machining aluminum sheet material. The vise deck is removed using four lifting rings and easily and accurately reinstalled using location pins.
