SOCIETE MECANIQUE DE LA GOHELLE (SMG)

What SOCIETE MECANIQUE DE LA GOHELLE (SMG) does

Société Mécanique de la Gohelle (SMG) is a French industrial engineering firm founded in 1986 in Noeux-les-Mines, Pas-de-Calais, and operating as a SAS with 12 employees and €240,000 in share capital. The company designs and constructs custom grinding machines (internal/external, horizontal/vertical, high-speed) and superfinishing machines for aerospace, automotive, and high-precision bearing manufacturers, while also offering full retrofit and modernization services across all machine brands including Bryant, Elb, Favretto, Jones & Shipman, Mikrosa, Studer, Tacchella, and Voumard. Its core competencies span mechanical engineering, electrical/automation systems (Siemens 840D, FANUC), hydraulic/pneumatic systems, and high-precision custom bearing manufacturing, including ceramic ball replacement and bearing adaptation. SMG also produces custom sub-assemblies (wheel heads, dressing attachments, automatic loading systems) and is the exclusive French distributor of KITAGAWA Europe clamping products and GMN lubrication/cooling units.

SMG's revenue model combines high-value, project-based custom machine construction and retrofit services (one-time contracts and professional services) with recurring hardware distribution income from KITAGAWA and GMN peripheral products, plus spare parts and on-site service revenue. The company operates a direct enterprise field sales motion from its headquarters, supplemented by event-driven demand generation at major trade shows (SIMODEC, Global Industrie) and co-organized technical days with partners such as CITIZEN. Since 2018, SMG has operated as a competence center within the PRACARTIS Group, which comprises eight specialized industrial entities supporting integrated precision machining solutions. In 2024, SMG secured exclusive KITAGAWA distribution rights, and in September 2025 it signed a strategic partnership with WORMSENSING to develop Dragonfly sensor-based machine monitoring solutions. The company's services are primarily delivered in France, with global footprint claims absent from available sources.
