Hole to Hole

Hole to Hole technology is a very effective way of manufacturing and building metallic aircraft. The principle lies in drilling holes for the connecting material already in the stage of metal cutting – milling process. The parts thus obtained are then passed on to other shaping operations – bending and forming. After the subsequent surface treatment, the parts are passed on to final assembly. The sophisticated Hole to Hole system ensures that the individual parts fit together with a minimum of finishing operations. The building process is graphically shown on the diagram below.

The main advantage of this system lies in its effectiveness. Implementation of HtH drastically reduces production costs and times, eliminates the need to use complex tools/jigs to mount individual parts in assemblies and reduces the need for experienced personnel. The main advantages include:

  • Low production costs
  • Smaller number of tools/jigs
  • Shorter production time
  • Low demands on staff experience

The advantages of this system will be appreciated especially by amateur builders, for whom the aircraft airframe assembly is very simple and comfortable.
