On July 3, 2012 we blogged about going big with a DENN CTA-660 CNC tube (cylinder) spinning machine. Now, about 1/2 a year later we go even bigger.
Currently being built is a DENN CTA-720 CNC tube (cylinder) necking-in machine.
This will be the current largest machine in the world for cylinder necking-in operations.
Diameters up to 711 mm (28 inch) and material thickness up to 40 mm (1.57 inch).
Lengths of tubes up to 13,600 mm (44.6 feet).
