CNC Machining Outsourcing for OEM Production
DEK works as an outsourced CNC production partner for OEMs and procurement teams that need overflow capacity, a second-source supplier, or a full-time machining partner without adding in-house equipment or staff.
Milling, turning, EDM and secondary operations run under one account. If your need spans beyond CNC into welding, fabrication, or assembly, sub-contract manufacturing solutions cover that broader scope; for pricing context, see our CNC machining cost guide.
Why Outsource Your CNC Production to DEK
These numbers reflect ongoing production relationships, the same track record a buyer checks before handing over a recurring order.
-
Two Decades of Precision
A precision machining track record spanning more than two decades, built on recurring production orders for OEM buyers rather than one-off jobs.
-
1.2 Million Parts a Year
Shop output tops 1.2 million critical parts each year, giving overflow and second-source programs the capacity they need without new equipment.
-
2,300+ OEM Clients
A client base of more than 2,300 OEMs across Europe and North America trusts DEK with standing production orders and repeat programs.
-
98.6%+ On-Time Delivery
On-time delivery holds above 98.6%, so scheduled releases land when your assembly line or customer program expects them, order after order.
No MOQ Contract Machining
Run one part or a standing production order: there is no minimum order quantity. Every quote includes a DFM review, and orders run under ISO 9001, ISO 13485 and AS9100D certification, all issued through TUV.
Contract Machining Capabilities
Milling, turning, EDM and secondary operations, held to tight tolerances and qualified on production materials, not just prototypes.
Contract Machining Services vs. Other Options
Choose contract machining when your parts are CNC-defined and need repeat production; multi-process builds and early design iteration fit other DEK services.
| Criteria | This ProcessContract Machining | Sub-contract Manufacturing | Rapid Prototyping |
|---|---|---|---|
| Scope | CNC production | CNC plus welding, assembly | Early design iteration |
| Best for | Overflow, second source | Broader multi-process scope | Iterating designs |
| Project stage | Prototype to full volume | Multi-process builds | Before design freeze |
| Choose when | Parts are CNC-only | Fabrication is needed too | Design still changing |

Part Sizes, Features and Hard Alloys
From micro-precision parts to roughly 1,000 mm structures, and the hard alloys that most often stall a shop mid-run.
-
Large Structural Parts
Structural parts up to roughly 1,000 mm are within scope for large part CNC machining work.
-
Micro-Precision Parts
Parts under 10 mm held to ±0.003 mm through micro machining and Swiss turning.
-
Complex 5-Axis Geometry
±0.01 mm profile control on complex parts machined on 5-axis centers, held across repeat production orders.
-
Deep Holes and Threads
Deep hole drilling and tapping run as secondary operations in the same order, without a second supplier.
-
Gear Machining
Gear machining runs as a secondary operation alongside milling and turning, within the same production order.
Hard Alloys We Have Validated
-
Ti-6Al-4V Titanium
Processes validated for Ti-6Al-4V, one of the alloys that most often stall a shop mid-run.
-
Inconel 718
Inconel 718 is stocked and validated for production runs, not just prototyping: one of the alloys that most often stall a shop mid-run.
-
17-4PH and 316LVM
Validated processes for 17-4PH and 316LVM stainless steels, qualified for production.
-
Supplier Switching
Prototypes scale into production under one account, so parts never need re-qualifying with a new supplier.
