Turbo housing

Turbo housing with exhaust manifold

Heat-resistant steel casting


The manufacture of exhaust manifolds and turbo housings on a machining centre presents particular challenges for tools and machines alike.

The machining process requires the highest levels of precision and wear resistance. The crucial machining operations for this process are: Milling the exhaust manifold surfaces and the relief grooves, counterboring the main bore and V-flange machining. In order to ensure a long tool life and stable processes, the focus is on designing the tools for maximum stability.

Rough milling of the exhaust manifold surface

Our solution:
Walter heptagon milling cutter with a double-sided indexable insert

  • 14 cutting edges
  • The latest Tiger·tec® Gold cutting tool material
  • Shim to protect the insert seat
  • Suitable for machining chrome-nickel steels

Benefits for you:
Long tool life and high feed rates for chrome-nickel steels.


Machining the side of the turbine

Our solution:
Walter combination tool for drilling

  • Drilling the main bore
  • Simultaneously: Forming the V-flange
  • Small number of tools in the magazine

Benefits for you:
The main bore can be machined with maximum productivity and high process reliability thanks to the stable process and low machining times.


V-flange: Interpolation turning

Our solution:
Walter interpolation tool

  • Two effective cutting edges for roughing operations
  • Cost-optimised indexable insert with 3 cutting edges
  • Cartridge system for double spindle machines

Benefits for you:
Low cutting material costs thanks to high tool life – while also providing short machining times.


Finishing V-flange and inner contours

Our solution:
Walter CaptoTM turning tool with two indexable inserts

  • Finish machining of V-flange and inner contours with just one tool
  • Stable insert on chrome-nickel steels, adapted indexable insert geometry

Benefits for you:
Long tool lives and high process reliability thanks to exceptional tool and indexable insert stability.
