What SEGM does

SEGM is a French precision machining workshop founded in 1972 in Tr\u00e9voux, operating from the F\u00e9tan industrial zone with facilities progressively expanded in 2009, 2013, 2014, 2017, and 2021. The company is family-owned, with second-generation G\u00e9rant David Gautheron (Arts et M\u00e9tiers engineer, promotion 1997) having taken over management in 2008 from founder No\u00ebl Gautheron. SEGM serves industrial B2B clients across nuclear, chemical, pharmaceutical, mining, food processing, plastics, and automotive sectors, including EDF (nuclear), producing unit pieces, small series, medium series, sub-assemblies, and emergency repairs of mechanical parts.

The technical foundation is a diversified CNC machine park including a GROB G350 horizontal 5-axis machining center, eight CNC turning lathes (with the DOOSAN PUMA 5100LYA 4-axis added in 2025 for a \u20ac300k investment), two Excetek V650G wire EDM machines, plus laser marking, a climate-controlled metrology room with a ZEISS CONTURA coordinate measuring machine and COFRAC-certified standards, and full finishing capabilities (welding, heat treatment, grinding, anodizing, electropolishing). SEGM holds ISO 9001:2015 certification since 2023 and joined the Nuclear Valley cluster in June 2025 to formalize its nuclear-sector activity that has been ongoing since 2011.

The business model is project-based B2B machining services with quote-based pricing (no public rates), delivering finished parts including accessories (gaskets, fasteners, circlips, keys) and identification labels ready for client installation. Revenue is generated through one-time project contracts and recurring series-production runs, distributed directly via two account managers (S\u00e9bastien Peronnier and David) plus a quality manager/business developer (Xavier Berthold, joined October 2025). Geographic focus is metropolitan France; client acquisition relies on professional network memberships (M\u00e9cabourg, UIMM Lyon, La French Fab, Nuclear Valley, Arts et M\u00e9tiers) and a content-marketing website rather than paid advertising. The 2015 strategic plan targeted \u20ac2M turnover by 2020; current revenue is undisclosed but ongoing investment cadence suggests growth beyond that target.

Core offering

SEGM is a precision mechanical machining workshop (job shop) that produces custom mechanical parts and sub-assemblies from customer drawings, models, or functional specifications. The offering covers unit pieces, small and medium series, mechanical sub-assembly with accessories, in-house finishing (welding, heat treatment, grinding, anodizing, electropolishing, laser marking), repair and maintenance of mechanical parts, and metallurgical consulting for industrial B2B buyers across nuclear, chemical, pharmaceutical, mining, food processing, plastics, and automotive sectors.

Product overview

SEGM operates as a precision mechanics workshop offering CNC machining services since 1972. The core product is precision machining covering unit pieces, small and medium series production, supported by a suite of specialized capabilities including 5-axis machining (GROB G350), multi-axis CNC turning (8 lathes including DOOSAN PUMA 5100LYA 4-axis, DMG MORI CTX series), wire EDM on two Excetek V650G machines, laser marking, and full finishing services (welding, heat treatment, grinding, anodizing). A climate-controlled metrology room with ZEISS CMM and metallurgical consulting round out the service portfolio. Finished parts are delivered with accessories and identification labeling.

Products and services

• Custom Precision Machining Services Contract CNC machining of unit pieces, small series, and medium series per customer drawings, models, or functional specifications, spanning turning, milling, and 5-axis operations. Intended for industrial buyers in nuclear, chemical, pharmaceutical, mining, food processing, plastics, and automotive sectors who need precision-tolerance mechanical parts without in-house capacity.
• Mechanical Sub-Assembly Manufacturing and Assembly Manufacturing and assembly of mechanical sub-assemblies for industrial clients, supplied finished with all accessories needed for installation (joints, fasteners, circlips, keys) and an item identification label so the assembly is ready to be placed on the client's storage shelf and integrated into its process. For industrial buyers seeking single-source delivery of complete, ready-to-install assemblies.
• Mechanical Part Repair and Maintenance Repair and maintenance of mechanical parts (shafts, sleeves, sub-assemblies) using specialised processes including shrink fitting, welding, and re-machining. Delivered as a service for clients' planned maintenance and emergency breakdown needs.
• Metallurgical and Technical Advisory Advisory service accompanying precision machining jobs: expertise in metallurgical choices, material selection, mechanical property improvement, and wear/abrasion resistance to optimise part performance for the service conditions. Aimed at industrial clients who need engineering input alongside machining, not just a finished blank.
