Motor Housing

-Machining Challenges-

One of the main components of e-vehicles is the Motor Housing that need to be considered with a special approach:

  • Light weight.
  • Durability.
  • Precision.
  • Surface finish.
  • Geometrical tolerances

These are key factors that have to be combined for each part. As cutting in the hollow structure during machining operations of motor housing can cause big deformations; the right combinations of cutting parameters, cutting geometries and tool technology are key factors for approaching this critical part in a reliable way. 

Characterisctics of the part:
  • Highest precision requirements (IT6).
  • Large amount of material to remove.
  • Thin walls and internal hollow spaces.
  • Highest reliability required.
  • High productivity required.
  • Large diameters.

SEMI-FINISHING

Light weight technology for process stability and appropriate PCD cutting technology ensure low cutting forces and a perfect chip control.
For a large tool diameter, innovative engineering solutions have been applied to minimize the tool weight, and the spindle load. Material such as titanium and carbon fiber are used for the tool body, as well as the framework design.
At the same time different solutions are studied also to allow the highest productivity.

OPTION 1.
Light tool body with indexable PCD cutting edges.

OPTION 2.
ultralight tool technology which adopts CFRP body and titanium head with PCD curtridges.

OPTION 3.
ultralight tool with framework steel body and indexable PCD tangential inserts and cartridges.

FINISHING

The tools developed for this application are examined to achieve the most critical geometries and technical requirements, they are designed with the best technology to ensure low cutting forces, high performance and a reliable process.
These tools process the heart of electric motor and guarantee high process stability and high quality surface.

OPTION 1.
Conventional tool tech with guiding pads and PCD adjustable cutting blades.

OPTION 2.
Ultra light tool with steel body, guiding pads and PCD adjustable cutting edges.

OPTION 3. Additive Tech.
Ultralight tool with high performance. Thanks to the innovative technology of 3D metal printing, highstandard requirements in terms of lightness, chip control and accuracy aer constantly achieved.

  • Light Additive tool technology.
  • Perfect shape for chip control.
  • Guiding pads and PCD adjustable blades.
