Special tools for milling

Huge challenges, strong tools

​

Machining very large cast parts such as turbine casings is a real challenge. Highly fluctuating profile measurements, major differences in diameter or considerable unbalances are just a few of the parameters which demonstrate that Walter special tools are the right tools for the job.

​
We develop special side and face mills for our customers, with diameters of over 2 meters. The uniqueness of the machining task is matched by the uniqueness of the special tool. For example, the degree of accuracy required for the profiles of turbine blades and turbine shafts used in steam turbines is extremely high. We will provide you with indexable insert finishing end mills for finishing blade roots and attachment grooves in turbine shafts: With these mills, you will be able to achieve a degree of profile accuracy of +/- 0.0004 inch (+/- 0.01 mm). The Walter Prototyp ConeFit™ system is one of the most successful modular tooling systems for milling.

Facts and advantages:

  • ConeFit™ is flexible and can be used for any type of machining
  • Modular design with different shank variants
  • Extremely high level of stability and precision due to support faces and taper contact surfaces with patented self-centering thread
  • Reduction in inventory costs thanks to very flexible and universal tooling system
  • Machine downtimes are reduced by changing the head directly in the machine

  • High machining productivity due to extreme rigidity
