How to choose your machining workshop
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.
Check the materials mastered
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.
Match the batch volume
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.
The industrial fabric of Cluses
Cluses is historically the world's heart of Swiss machining (bar turning), an activity born in the 19th century in the Arve valley with the manufacture of screws for the watchmaking industry. This unique industrial heritage has shaped an ecosystem where family-run SMEs and specialised workshops coexist side by side, clustered notably in the Vouilloux and Ewües industrial zones. The high density of bar turning specialists — illustrated by players such as Bibollet Décolletage, Technic Vallée Décolletage, FML Décolletage or BA Usinage — reflects the ongoing continuation of this local know-how in machining small-diameter metal bars to tight tolerances.
Beyond traditional Swiss machining, the industrial fabric of Cluses has evolved towards complementary processes: 5-axis milling, grinding, lapping and sinker EDM are now practised locally, notably to meet the requirements of the aerospace, medical and automotive sectors. Workshops such as Kolly Précision, Paris Savoie Industries or the 5-axis workshop on Chemin de Pressy illustrate this technological upgrade, firmly positioning Cluses in high-precision industrial subcontracting well beyond the watchmaking screw-making origins that first put it on the map.
