Durchgängiger Prozess für die Elektromobilität
Innen- und Außenbearbeitung des topfförmigen Statorgehäuses
Mit steigenden Stückzahlen der Elektrofahrzeuge sind nicht nur sehr exakt gefertigte Bauteile, sondern auch eine möglichst effiziente Produktion gefragt. Eine in der Zerspanung besonders anspruchsvolle Komponente ist das Motorgehäuse für den Elektromotor. Zur Bearbeitung der Statorbohrung hat MAPAL bereits eine dreistufige Lösung etabliert und legt nun mit einem großen Werkzeug für die Außenbearbeitung nach.
Dreistufige Lösung für die Statorbohrung
World first for external machining
On the outside, the part features a helical circumferential groove. Because the coolant later flows through this groove after it’s been inserted into the outer housing, the stator carrier is also known as the "cooling jacket".
MAPAL is presenting new external machining tools at the EMO in Milan. They are among the more unusual tools. After pre-machining, a bell-shaped tool takes over the complete finishing of the outside. The specifically designed lightweight tool is equipped with indexable inserts and guide pads and was provided with bars in the right places to save as much weight as possible and to get rid of chips through large openings. The fine machining tool promises high roundness and accuracy.
Complete machining on machining centre
Internal machining is possible very quickly and accurately with the boring tools. In addition, the outside can also be machined in the same clamping setup without moving. The machining centre solution caters to customers who are embracing the transformation to e-mobility with existing machinery geared to machining large cubic aluminium housings.
Those who start their production on a greenfield site can, of course, choose which machining strategy is best for them. MAPAL has developed an alternative machining solution in a joint project with a machine manufacturer. In this case, the process was rotated 90 degrees for use on vertical lathes.
