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.
Colmar, the county town (préfecture) of the Haut-Rhin département, benefits from an Alsatian industrial fabric historically geared towards precision mechanics and metal processing. The central Alsace plain, well served by the A35 motorway and its proximity to the Rhine border, has encouraged the establishment of SMEs and specialised workshops meeting the needs of regional industry, particularly in mechanical equipment, food processing and intermediate goods.
The business parks of Colmar and neighbouring towns such as Ingersheim host companies with complementary profiles: versatile workshops mastering both milling and turning (SAMG, JMP Assemblage, Atelier Mécanique Rgeiger SA), Swiss machining specialists (CSA, Schoettlé 68), and units with extended capabilities such as grinding and deep-hole drilling (PROMECA, EURAMECA). This diversity of processes available within a short distance is a real asset for Haut-Rhin manufacturers seeking responsiveness.
