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.
Exigências da usinagem e características dos diferentes tipos de carcaça
Procedimento básico para usinagem da carcaça do estator
O processo de usinagem e as ferramentas são projetados individualmente, dependendo da situação da medição, do modelo da máquina e da fixação. Desta forma, as forças de corte aplicadas à peça são mantidas tão baixas quanto possível. A usinagem do furo do estator está dividida em três etapas: Pré-usinagem, usinagem de semiacabamento e usinagem de acabamento.
