HHV Extrusion Mill
The Modig HHV for aircraft extrusions of various kinds. Typical parts are longerons, stringers, floor beams, seat tracks, clips any many other parts. The machine has become very popular among the world leading aircraft manufacturers. Companies like Boeing, SAAB, Airbus, Raytheon, Cessna, Gulfstream, Embraer, Bombardier and many subcontractors have already invested in a number of the original Profileline machines. The Modig Profileline HHV is an updated version of the very popular original Profileline machine.
The HHV is capable of machining parts in composite and aluminium materials. The cross section of materials can be up to 10” (250mm) and the length unlimited This allows the HHV to fulfil needs in both aerospace, and construction industry.
The machine is very cost effective, represented in the following examples:
- The investment is relatively low.
- The machine provides high productivity.
- The system floor space is small yet has the capacity for aluminium and carbon fibre extrusions up to approximately 60’.
- No special foundation is required.
- The fixture and tooling costs are small.
- The precision is very high
The machine can be built to specific requirements. Machines have been installed with 20,000 to 45,000 maximum rpm spindles. Additionally, the system is available with Heidenhain, Siemens, or GE/Fanuc CNC controllers. GE Fanuc is the standard control.
This arrangement provides:
- The rotary chucks can be moved left or right relative to the opposite rotary chuck (closer or farther away for optimum work piece support).
- With the U-axis, the work piece can be shuttled through the machine in both directions with high accuracy, regardless if the final part is 1” long or 60’.
- The rotation of the rotary tables is performed by servomotors connected in the control as one axis. The position feed back is direct, for the highest accuracy.
- The U-axis can be extended, from 1000mm (40”) to 2300mm (90,5”).
- A saw can be mounted on the machine bed operated with one ore two axes from the main CNC control. With a tilting axis on the saw there is a possibility to cut compound angles by using the rotation of the rotary axis in combination.
