Thermal shafts are fitted in steam turbines. They are often around 10 metres long and weigh over 100 tonnes. It often takes months to machine them, with up to 20 t of chips being produced. Machining this type of stainless-steel shaft is generally considered one of the most demanding machining tasks.

This particularly applies to machining of the precision mounting grooves. As a result of a component-specific machining process developed individually for the user, Walter ensures that machining is both accurate to size and cost-efficient.

This is implemented in production with our highly precise special tools for milling, planing and grooving
