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 Clermont-Ferrand
The Clermont-Ferrand area developed around a manufacturing industry historically driven by the automotive and rubber sectors, a legacy that has long shaped local demand for precision machined parts. Today, aerospace has become a dominant industry: several listed workshops, such as Montferrand Mécanique, MGR, Atelier Mécanique des Dômes and Mendès Mécanique Générale, explicitly state that they work for this sector, reflecting rising quality requirements and mastery of advanced processes such as 5-axis milling, high-speed machining (HSM) and deep-hole drilling.
The workshops are spread across several business parks of the Grand Clermont area: the Gerzat industrial zone is home to Mecauv Industrie and MGR, while Lempdes brings together two subcontractors focused on aerospace and rail. Further north, Riom rounds out the offering with UMC Usinage Mécanique du Centre, active in the nuclear energy sector, illustrating the sector diversification typical of this Auvergne industrial basin.
