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.

Procédure de base pour l'usinage de boîtiers de stator
Le processus d'usinage ainsi que les outils sont conçus individuellement en fonction de la configuration dimensionnelle, du parc de machines et de la fixation d'outils. Les forces de coupe agissant sur le composant sont donc réduites au maximum. L'usinage de l'alésage du stator est divisé en trois étapes : pré-usinage, usinage de semi-finition et usinage final.
