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.

不同外壳体类型的切削加工要求和特征


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.

定子壳体的外部加工

电机定子壳体的外部加工是一项艰巨的高要求加工任务。这些壳体对于电机的效率具有至关重要的作用,通常采用管状或罐形设计。在该加工工艺流程中,必须克服一系列的难度挑战。薄壁型铝制壳体上带有用于冷却循环散热的集成加强筋,基于该类别工件在直径精度、形位公差上的要求,对应的加工要求需要达到极高的精度。保证各种不同直径之间的同心度在加工中具有非常重要的意义。
