Engine housing

Engine housing machining

Nickel-based alloy


Turbine housings are designed for maximum stability. For this reason, they are made of materials such as titanium alloys, Inconel or Waspalloy. Nickel-based alloys in particular are very difficult to machine due to their high toughness and temperature stability. In addition, it must be ensured that finishing work does not cause any structural changes or damage to the component.

Multi-axis turn/mill centres and vertical turret lathes are primarily used for machining these materials. Walter tools for turning, milling, drilling and threading enable you to machine engine housings with maximum efficiency, precision and process reliability
