Electric drives place higher requirements on surface and gear quality, as well as on geometric tolerances with their high speeds from 15,000 to 30,000 rpm. WMZ machines for soft machining and Buderus machines for hard fine machining are suitable for complete machining –  the number of clamping processes and potential sources of error are significantly reduced.

More important for final product quality are the finely tuned DVS technology systems: Tools, processes and machines within the system are ideally matched, specialists from the individual Group companies are in constant contact with each other and ensure for mutual know-how transfer.

The advantage in quality achieved is not only measurable, it can also be experienced: The significant “Noice Vibration Hardness” (NVH) leads to a noticeably quieter, pleasanter driving experience.

Future-oriented production must also be economically convincing, to be successful in the medium term. The DVS TECHNOLOGY GROUP system solution ensures that the demand on quality does not  come into conflict: The modular complete and combination production needs less machines and work steps – and hereby reduces the aquisition and maintanence costs, saves place, energy and personnel. The unit costs sink by 30 to 40 % in comparison with  conventional processes – without loss of performance in rotor shaft production.

Whatever the future will bring – one thing is certain: It will bring change. The ability to react quickly and flexibly to changing conditions and demands is a necessary prerequisate for the future viability of a company; it provides the required investment security. The DVS TECHNOLOGY GROUP technology system is constructed modularly. The subcomponents can be adapted or expanded at any time – e.g. with automation. In the case of rotor shafts for electric drives the following components make up the efficient complete solution: The complete production machine from WMZ for complete soft machining of the quill; and, after hardening, the Buderus Schleiftechnik uFlex and 235V machines and the PRÄWEMA Antriebstechnik power-honing machines take over for the hard fine-machining.
