Electrified drives
Automobile manufacturers and suppliers are facing new challenges when it comes to components for electric motors. The example of the housing of an electric motor shows how big these challenges are: Compared to a transmission housing, this has to be manufactured within significantly tighter tolerances, since the accuracy has a decisive influence on the efficiency of the motor.
In addition, due to the special structure, such as integrated cooling channels, the electric motor housing is usually significantly thinner than a transmission housing. In addition, bearing bushes made of steel materials are pressed into some of these housings. Special protection shields in the tool ensure that steel chips do not come into contact with the aluminium surfaces during processing and damage them.

Procedura di base per la lavorazione del corpo statore
Sia il processo di lavorazione sia gli stessi utensili vengono realizzati a seconda della situazione dimensionale, dell’impianto industriale e del sistema di serraggio. Questo mantiene le forze di taglio che agiscono sul componente al livello più basso possibile. La suddivisione della lavorazione del foro statore avviene in tre passaggi: prelavorazione, semifinitura e lavorazione di precisione.
