Aircraft & Helicopter Tube Bending Applications

HMT builds precision tube benders for forming tight radius bends on thin wall tubing used for aircraft tube bending industry industry. Our machines are equipped with the following outstanding features:

 

  • All Electric servo driven for precise control.

  • Highly rigid tooling guiding used for precision bending of difficult alloys found in the aircraft bending industry.

  • Precision linear bearing guided pressure die with electric servo following. This causes the pressure die to follow the speed of the bend die automatically. The operator can also advance or retard the pressure die movement by a percentage directly from the control system.

  • Our precision clamp and pressure die drive systems deliver the exact force needed for aircraft tube bending.

  • Retractable wiper die base with electric servo actuation which moves the wiper out of the way so the carriage can advance closer to the bend die. This results in material savings on costly alloy tubes used in aircraft tube bending. The precise electric servo system insures correct and repeatable position of the wiper die.

  • Electric servo mandrel with guided linear bearings. This removes the load from the mandrel rod. Our precise electric servo driven system produces extract positioning of the mandrel and power to extract the mandrel early. The unit also allows the mandrel rod to spin freely to avoid losing rotation orientation in the collet on tight fitting mandrels.

  • Porting of the bend head for using a water jacket to provide cooling for “Hot Bending.”

  • Programmable pressure settings for precision control during thin wall alloy bending.
