Turbine housing

 Alloyed steels and steel casting

Manufacturing housings for energy production systems is precision work involving many time-consuming process steps. The complete solutions we offer for all process stages involved in machining operations in the power generation industry are highly efficient.

We can provide you with the right tool for each individual cut: For milling, drilling, threading and turning. Walter solutions reduce tool change and chip-to-chip times to a minimum without compromising on quality. At the same time, they reduce the number of clamping operations needed and therefore reduce non-productive times. This means that you can achieve more added value.


Milling grooves in the flat position

Solution:

Walter WF351 slotting cutter

  • ► Flexible cartridge system for roughing and finishing cartridges
