3D printed stator bore tool for the machining of aluminum e-motor housings.

This version of the tool features a newly designed arm structure, a larger center tube made of carbon fiber, and weighs a total of 7.3kg.

The complex tool is capable of machining three large diameters in just one operation, saving set-up time and machining time for automotive component manufacturers and delivering the highest accuracy and surface qualities.

Machining three diameters in one operation, the stator bore tool ensures the alignment and concentricity of the machined surfaces whilst reducing the cycle time significantly.

The lightweight 3D printed combination tool enables a faster tool change and spin-up even on less powerful machines.

  

  

Design Evolution

First-generation design (9.5kg) on the left, and latest tool design variants (less than 8kg) on the right for hassle free tool changing.
