電気駆動
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.

スタータハウジング加工時の基本手順
加工プロセスおよび工具は、取り代の状況、機械装置、クランプシステムに応じて個別に設計されます。そうすることで部品に作用する切削力が可能な限り低く保たれます。スタータ穴の加工は、3つのステップに分かれています。前加工、中仕上げ加工および仕上げ加工に分けられます。
