Choosing a machining subcontractor depends first on the nature of your part. A part of revolution (shaft, ring, axle) calls for turning; a prismatic part with complex shapes calls for milling, ideally 3 or 5 axes. For shapes impossible to obtain by conventional cutting, EDM becomes necessary.
Not all workshops work the same materials. Aluminium and steel are almost universal; stainless steel, titanium and superalloys require more expertise and suitable tooling, common in aerospace- and medical-oriented workshops.
For a prototype or a one-off part, favour a responsive workshop with a design office. For medium or large batches, machine capacity and automation become decisive for the unit price.
Workshops in the area cover most material-removal machining processes.
Lille and its metropolitan area carry an industrial heritage rooted in materials processing, inherited from the great decades of the textile and metalworking industries of the Nord region. Today, this heritage translates into a concentration of general and precision machining workshops spread across business parks in the city and neighbouring areas such as Lomme, part of Lille Métropole. Proximity to the A1, A25 and A27 motorways facilitates logistics flows towards regional, Belgian and Paris-area customers.
The Lille machining sector stands out for combining generalist workshops — skilled in conventional and CNC turning and milling — with specialists positioned in demanding industries. Nord Metal Services serves the aerospace sector with 5-axis milling capability, while Matechplast focuses its production on medical applications. The presence of processes rarely found locally, such as wire and sinker EDM at Mecasoka, strengthens the ability of the Lille area to handle complex geometries without relying on subcontractors outside the region.
To dig deeper before launching your machining project.
The 8 listed workshops in Lille and Lomme cover turning, milling (including 5-axis milling), Swiss machining (bar turning), grinding, as well as wire and sinker EDM.
Yes. Nord Metal Services is positioned in the aerospace sector with 5-axis milling capability, and Matechplast serves the medical sector, offering turning, milling and Swiss machining (bar turning).
EDM (electrical discharge machining) is a spark-erosion process used to machine hard materials or highly complex shapes. In Lille, Mecasoka offers both wire EDM and sinker EDM, in addition to turning, milling and grinding.
Seven workshops are based in Lille itself. An eighth facility, specialising in general mechanics and stainless steel Swiss machining, is located in Lomme, a commune now part of Lille Métropole.
