Crankshaft

 Steel and cast iron

High tolerance and surface quality requirements make crankshafts exceptionally complex to machine. Highly precise, efficient tool concepts are necessary to meet these requirements.

As far as the economy of the machining process is concerned, increasingly efficient tools have to be developed and deployed. Solutions tailored to specific customer needs are created and continuously further developed together with our partners and machine manufacturers. The new indexable inserts with Walter Tiger·tec® Gold technology are just one example of this. These are the foundations on which you can continuously build on your success and increase your lead over the competition.
