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.

Grundlegende Vorgehensweise bei der Bearbeitung von Statorgehäusen
Der Bearbeitungsprozess sowie die Werkzeuge werden je nach Aufmasssituation, dem Maschinenpark und der Aufspannung individuell ausgelegt. So werden die auf das Bauteil wirkenden Schnittkräfte möglichst geringgehalten. Die Bearbeitung der Statorbohrung ist dabei in drei Schritte unterteilt: Vorbearbeitung, Semi-Finishbearbeitung und Fertigbearbeitung.
