Used drive, control and regulation technology
This category differs from the other machine categories: Here you will not find complete machines, but rather control assemblies, drive modules, operator panels, safety switches, and control cabinet components. At MHD Maschinenhandel, these parts primarily originate from the dismantling of complete machines and systems—a direct advantage of our affiliation with the AVV Group, which provides us with ongoing access to dismantled components before machines are scrapped.
Our focus is on control technology from Siemens, particularly from the Simatic, Simodrive, Sinamics, and Sinumerik series. We also carry components from other manufacturers such as Heller, Euchner, Rittal, Sauter, Klaschka, AEG, Weiss, and Keba, as well as sensors from ifm electronic.
Here you will find our current selection of used machines in this category. Drive and control technology – Available immediately and directly from our stock. Use the filters to quickly find the right machine.
Tell us your specifications – we will contact you as soon as a suitable machine becomes available.

Original part or aftermarket solution: when is a used component worthwhile?
For many older machine tools, the manufacturer eventually discontinues the supply of spare parts, even though the machine's mechanical components are still functioning perfectly. In this situation, companies face the choice between a costly control system retrofit with new hardware and software or replacement with a used, identical component. An original, tested used component can usually be installed without reprogramming or adjusting machine parameters—a significant time and cost advantage compared to a complete control system replacement.
What to look out for when buying
- Exact controller type and version, such as Sinumerik 840D or 810D
- Assembly and order number for unambiguous compatibility
- Firmware or software version of the component
- Condition of circuit boards, connectors and terminals
- Existing accessories such as batteries, cables and documentation
- Origin of component: from dismantling or from stock
Wherever possible, we indicate whether a component was operational before removal and was taken out in working order. In the case of control technology, this is a more important indicator than the year of manufacture alone.
Why buying used is worthwhile
For maintenance, the used market for drive and control technology is often the only realistic source for continuing to operate an otherwise functional machine even when spare parts are no longer available. This applies particularly to existing machines in the following sectors: Lathes, Milling machines and Boring mills / machining centres, whose mechanical integrity far exceeds the availability of the original control unit. A used component costs a fraction of what a complete control unit modernization would require in terms of investment and downtime.
