DMG Mori Control Generation
Way Covers for Siemens 840D Era Machines
Way covers on DMG Mori machines running Siemens 840D span a wide age range — from late-1990s original 840D builds through current solutionline machines. Original 840D era machines (roughly 1998-2010) increasingly require custom fabrication; solutionline era (2010-present) is mostly OEM-available. The control side is separate from the cover work but the era helps frame parts availability.
Machines this control shipped on
Siemens 840D ships on most of the DMG Mori lineup — NLX/ALX, CTX/CLX, NTX, NHX/NH, NVX/NV/NVD, CMX, DMP/Milltap, SPRINT/MULTISPRINT, and the DMC variants.
Common failures and fixes
- Original 840D era machines (pre-2010) increasingly route through custom fabrication.
- Solutionline era machines (2010-present) are mostly OEM-available.
- Telescoping steel is the default cover style on most Siemens-controlled DMG Mori machines.
- Era split is rough — some configurations stayed OEM-available longer than others.
Parts availability
Original 840D era way covers are increasingly custom-fab; solutionline era machines have OEM availability through DMG Mori. The split shifts year over year as inventory thins on the older builds.
Battery, memory, and parameter recovery
Custom fabrication to your existing cover, the OEM drawing, or measurements off the machine is the standard path for discontinued covers. Mounting hardware on Siemens-controlled DMG Mori machines is typically well documented. Lead time is 2 to 4 weeks.
