UNISON has supplied a second all-electric tube bending machine to Boeing Integrated Defence Systems’ facility in Philadelphia.
Unison says its Breeze 20 tube bending machine is capable of making precision bends on high performance alloys and aluminium tubes with diameters of up to 20mm.
It is being used by Boeing to fabricate hydraulic and fuel line components for Chinook helicopters. The latest model of the Chinook helicopter, the CH-47F, has an airframe which uses larger single-piece sections than previous models.
According to Unison, the Breeze 20 bending machine features a ‘long nose’ which allows it to shape tubes with complex bends, and very short distances between bends in a single fully-automated operation.
The Breeze 20 tube bending machine uses servo motors instead of hydraulic force to control the tube bending process. Unison says the all-electric actuation keeps the manufacturing operations precise, repeatable and energy efficient.
Unison claims each of the tools employed during bending is under software control, allowing operators to create smooth bends with optimal flow performance and strength.
