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.

The industrial fabric of Annecy
Annecy has built a solid industrial identity around precision engineering, a direct legacy of the watchmaking and Swiss machining tradition that has shaped the nearby Arve Valley (Vallée de l'Arve) for decades. This historical metalworking know-how has fostered the emergence of specialised workshops capable of meeting the tight tolerances demanded by the aerospace and medical sectors, both well represented among local clients.
The listed companies are mainly concentrated in the business zones of Annecy and the neighbouring town of Chavanod, part of a dense industrial ecosystem in Haute-Savoie. Complementary capabilities are available here: series bar turning at LJ Industries and DDI, 5-axis milling geared towards aerospace at Gemma, and wire and sinker EDM at EFOP Erosion — a rare process that reflects the level of specialisation reached in this area.

Frequently asked questions
What machining processes are available in and around Annecy?
The 10 listed workshops cover turning, milling (including 5-axis milling), Swiss machining (bar turning), grinding, and wire or sinker EDM. This diversity allows for the handling of both complex one-off parts and high-volume bar-turned series.
Are there workshops specialising in aerospace machining in Annecy?
Yes, several workshops state that they work for the aerospace sector: Teissier Technique in Chavanod, Magnin Mécanique Générale, EFOP Erosion and Gemma in Annecy. Gemma notably offers 5-axis milling, a process commonly used for aerospace structural parts.
Can you find a medical machining workshop in Annecy?
Two listed workshops explicitly mention the medical sector: Teissier Technique (Chavanod) and EFOP Erosion (Annecy). The latter carries out EDM, a process well suited to implants and surgical instruments made from hard-to-machine alloys.
What is the difference between Swiss machining (bar turning) and CNC turning?
Swiss machining, or bar turning, refers to the high-volume production of small-diameter parts from bar stock, using multi-spindle or CNC sliding-head lathes. CNC turning applies to a broader range of parts, often in smaller batches or as one-offs. In Annecy, LJ Industries and DDI specialise in bar turning, while most other workshops offer CNC turning.
