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.
Machining requirements and features of different housing types
Procedimiento básico para el mecanizado de carcasas de estátores
El proceso de mecanizado, así como las herramientas, se diseñan individualmente según la situación de medida, el parque de máquinas y la configuración de sujeción. De este modo, las fuerzas de corte que actúan sobre el componente se mantienen lo más bajas posible. El mecanizado del orificio del estátor se divide en tres pasos: Premecanizado, semiacabado y mecanizado de acabado.
