Turbine Disks
Information
Disks for turbines are among the most highly stressed components in the engine, as they are installed directly after the combustion chamber in the hot section of the engine. Maximum precision and reliability are crucial in the manufacture of these components. For this purpose, many different shapes and surfaces are precisely manufactured and assembled over several process steps. In addition, there are maximum requirements for surface quality and processing, such as roughness
Areas of Use
The generic term turbine discs includes a large number of similar, rotating components in the hot section of the engine, which are permanently exposed to the highest loads, especially due to thermal loads. These include usually the high-pressure turbine and the low-pressure turbine.
Manufacturing
The main processing methods used here are cutting processes such as turning and milling, but also special processes such as coating, etching, shot peening and broaching. When broaching, a broaching tool is pulled through the disk to create the mounts for the blades of the respective turbine disk. A very effective and high-precision process that produces even the most complicated shapes with the highest precision with just a single stroke.
