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.
The Lyon metropolitan area relies on a dense and diverse industrial fabric, inherited from a long mechanical tradition. The Chassieu and Corbas business parks, located east of Lyon, host workshops such as Ets Auberger and TVI Brandolini, the latter working notably for the rail, aerospace and defense sectors with 5-axis milling and gear cutting capabilities. Décines-Charpieu, another industrial hub in eastern Lyon, is home to Établissement Verne, specialized in turning and milling.
In Villeurbanne, LISI Medical Fasteners illustrates the strong presence of the medical device industry within the Lyon ecosystem, producing machined parts for the medical sector. Within Lyon itself, several workshops — Chambon SAS, Mécano Technique, Guillaume SARL, C.F.U.P, SEREMO and VCN Technologies — form a local mechanical subcontracting network, offering turning, milling and Swiss machining for a variety of clients across the Auvergne-Rhône-Alpes region.
The listed workshops in the Lyon metropolitan area show a strong orientation toward high-requirement sectors. TVI Brandolini, based in Corbas, explicitly works in aerospace, defense and rail, offering advanced processes: 5-axis milling, grinding, lapping and gear cutting. This last process, uncommon among generalist subcontractors, signals the capability to produce complex transmission parts subject to strict specifications. LISI Medical Fasteners, in Villeurbanne, is positioned in the medical sector, which implies requirements for traceability, biocompatible materials and tight tolerances.
For the other workshops — C.F.U.P, Chambon SAS, Guillaume SARL, Mécano Technique, SEREMO, Établissement Verne and Ets Auberger — the declared processes are turning and milling, with grinding also offered by Auberger, and Swiss machining by C.F.U.P. Swiss machining indicates an ability to produce small parts in large volumes from bar stock. Auberger's grinding capability, in Chassieu, rounds out the offering for parts requiring fine surface finishes or very tight dimensional tolerances.
A buyer looking for a standard turned/milled part will find several possible contacts within Lyon itself. However, for simultaneous 5-axis milling, gear cutting, or a part destined for certified aerospace use, the offering is concentrated in Corbas. For implantable medical devices or surgical fasteners, Villeurbanne is the natural point of contact within this directory.
Before contacting a workshop in Lyon, prepare a complete technical file: a dimensioned 2D drawing with tolerances and surface finish specifications, a 3D file (STEP or IGES preferred), a precise material designation (standardized grade, not just "stainless steel"), the desired quantity and, if possible, a target lead time. In Lyon, several workshops coexist with distinct positioning: an incomplete file will lengthen exchanges and delay the quote, especially with subcontractors working for aerospace or medical clients, where drawing review is formalized.
What causes a quote to vary here is above all geometric complexity and the required process. Simple turning on conventional machinery does not command the same price as 5-axis milling with lapping and gear cutting, such as TVI Brandolini can offer in Corbas. Material also plays a role: machining titanium or high-strength alloys — common in medical or aerospace applications — requires specific tooling and longer cycle times. Batch size directly affects unit cost: Swiss machining as practiced at C.F.U.P is economical for large runs but poorly suited to single prototypes.
Geographic proximity really matters when you need to shuttle parts between several operations (turning then grinding, for example), or when you want to visit the workshop to approve a first article. The Lyon metropolitan area allows you to combine several suppliers within thirty minutes' travel, which is a logistical advantage worth using. Check first for certifications relevant to your sector: EN 9100 for aerospace-defense, ISO 13485 for medical. If no listed workshop holds the required certification, look toward Grenoble or the Swiss-machining clusters of the Ain department.

To dig deeper before launching your machining project.
The 9 listed workshops offer at minimum turning and milling. Grinding is also available (Ets Auberger in Chassieu, TVI Brandolini in Corbas), as is Swiss machining (C.F.U.P in Lyon), 5-axis milling, lapping and gear cutting (TVI Brandolini). Coverage is broad, but 5-axis milling and gear cutting are concentrated at a single site.
Cost depends on the process, material, tolerances and quantity. Simple turning in a standard batch is less expensive than a 5-axis milled part in a special alloy with grinding. The data from the listed workshops does not allow us to provide indicative rates: request a quote based on your drawing, specifying material, quantity and tolerances.
Lead times vary depending on the workshop's order book, part complexity and any external treatments required. No standard lead time is published by the listed workshops. State your scheduling constraint as soon as you request a quote: some workshops can prioritize urgent orders, while others run busy schedules tied to recurring aerospace or medical clients.
Minimum quantity thresholds vary by process and workshop. Swiss machining (C.F.U.P) is generally better suited to large runs than to single prototypes, due to setup times. Conventional turning and milling can accommodate single parts or small batches. Ask the workshop directly, specifying your volume.
Prepare: a 2D drawing with all dimensions, geometric and dimensional tolerances, and the required surface finish; a 3D file (STEP preferred); the standardized material designation; the desired quantity. For medical or aerospace sectors, add any regulatory or traceability requirement applicable to your part.
For aerospace and defense, EN 9100 certification is the benchmark; check that it is up to date at TVI Brandolini if you approach them. For medical applications, ISO 13485 is essential; LISI Medical Fasteners operates in this market. If the required certification is not held by the workshop you contact, look for a certified supplier outside Lyon.
CNC turning and milling commonly achieve tolerances on the order of a hundredth of a millimeter. Grinding (available at Ets Auberger and TVI Brandolini) allows for tighter tolerances and finer surface finishes. Lapping, offered by TVI Brandolini, further reduces roughness. Specify your requirements on the drawing: this is the only way to get a firm commitment from the workshop.
If you need a process not covered by this directory (EDM, laser metal processing, metal 3D printing, heat treatment), if no workshop holds the required sector certification, or if your batch requires very high-cadence Swiss machining not available locally, look toward Grenoble, the Ain department (Oyonnax, Bellegarde), or the Arve valley for Swiss machining.
