The master cylinder of the landing gear, along with the connecting elements, provide the suspension and absorbs impact during landing. The complex design enables the landing gear to be extended and retracted within seconds. Depending on the size of the aircraft, there are different versions in terms of number and overall size. Since these components must satisfy the most rigorous safety standards, only very few materials qualify for use, principally titanium alloys and 300M.
The complexity of the components is constantly increasing, as an ever higher number of add-on parts are being integrated into the forging blank in new models. Contour milling, turning and boring are therefore among the most important methods of machining in the manufacture of the landing gear main cylinders.
The optimal machining strategy is demanded here, in addition to the tool technology.
