TMUA - Expert en systèmes d'abrasion

What TMUA - Expert en systèmes d'abrasion does

TMUA is a French specialist manufacturer of industrial abrasive system machines, headquartered in Langeac, Auvergne-Rhône-Alpes, and operating since 1984 as a wholly-owned subsidiary of SIBIM Group. The company designs and builds both standard catalog machines (belt tensioners, centerless polishers, combination grinders, working units) and fully custom-engineered special machines for polishing, deburring, grinding, sanding, and superfinishing applications. Through the 2020 acquisition of AM2S and the 2021 acquisition of SPMS Supramatic's intangible assets, TMUA gained abrasive consumables distribution and patented CMA superfinishing technology respectively, positioning it as the leading French supplier of superfinishing and deburring solutions for automotive powertrain components (crankshafts, camshafts, gears, steering racks) used by OEMs such as Renault, Peugeot Citroën, Ford, Ferrari, Volkswagen, Daimler, and Safran.

The company's technical differentiation rests on in-house integrated manufacturing: mechanical design (Top Solid), automation/robotics engineering (IGE XAO See Electrical Expert), CNC machining, boilermaking, and electrical/mechanical assembly are all performed at the Langeac facility, enabling quote-based custom machine delivery with short lead times. SPMS technology delivers measurable performance gains (circularity improvement of 50%, cylindricity tolerance below 3 microns, production rates of 60–120 parts/hour), and the 500+ SPMS machines installed globally create a captive spare parts and after-sales service revenue stream. Revenue is generated through hardware sales (new machines, used/refurbished machines via the e-commerce boutique), professional services (aftermarket support), and consumables through AM2S. Reported revenue was €3.8M in 2024 with 32 employees, up from €2.7M in 2021.

TMUA sells primarily through direct B2B engagement (phone, email, website), complemented by inherited SPMS international sales partners for global reach. Verticals served include automotive (primary), aerospace, agriculture/heavy equipment, luxury leather goods, cooperage, medical devices, and jewellery. The company operates as part of SIBIM Group alongside AVITECH (agri-food machinery), DELRIEU (precision mechanics), and POLYNOV (custom engineering), benefiting from shared design offices and group-level investments.
