The combustion chamber of an aircraft turbine is a system of superlatives: for instance, temperatures and pressures go sky-high when the compressed hot air and kerosene are ignited. This places tremendous demands on the construction material, which means heat-resistant super alloys are the only option. However, these can only be machined using extremely tough tools.
To ensure that the required level of efficiency is maintained in the face of all these challenges, we have optimised our tools for both long haul and shorter domestic flights.
Machining of smaller areas and pockets in titanium or Ni-based alloys
Roughing of Ni-based alloys at impressive cutting speeds
Turning finish machining with low cutting forces
For precise drilling with the perfect finish
Thread milling with special solid carbide milling cutters
