Electrified auxiliary units
As a result of electrification in the automotive industry, more and more drive tasks
of the internal combustion engines are being performed by electrified components.
By electrifying the auxiliary units, these components can be used as required and
depending on the load, and thus contribute to reduced energy consumption. They
stand out thanks to their high reliability and low noise emissions as well as excellent
energy efficiency.

Auxiliary unit scroll compressor
An example of an electrified auxiliary unit is the scroll compressor, which is used as an electric refrigerant compressor in thermal management. Three specific machining operations on an aluminium scroll compressor for use in an electrified vehicle are presented as examples.
FEATURES
- Core pieces orbit and fixed scroll
- Geometric accuracy and connection is paramount
- Exact positioning of the spirals to each other
MACHINING REQUIREMENTS
- High degree of shape accuracy of the spirals (≤ 20 μm)
- High perpendicularity of flanks to base surface (≤ 20 μm)
- Parallel alignment and flatness of ≤ 10 μm
- Surface roughness (Rz) in the single-digit range
- Perfect interaction between machine and tool
