Generators have to convert the rotational energy of turbines into electrical power with the greatest possible efficiency. To do so, the key component of generators, the electrical shaft, must be manufactured with extreme precision.
This is no easy task, as generators are up to 15 m long and weigh more than 200 t – with main winding grooves up to 250 mm deep and up to 9 m long. With Walter's tool and machining concept, winding grooves can be roughed and finished in a single pass. This is accompanied by a comprehensive range of standard and customer-specific solutions for high-precision manufacturing of winding, air, sealing and relief grooves
