30-foot Long Table for Curtain Wall Machining
In 1999, CNT built the first of several machines designed to drill and mill 30-foot 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 with 30 inches of table travel, requiring frequent indexing of the part.) With the 30-foot bed, pivoting head, automatic tool changer and alcohol/oil coolant system, the CNT machine provided a single-step, automated solution.
Check out the 24-foot, two-panel processing machine we built for the same industry.
