Geminis Lathes

What Geminis Lathes does

Geminis Lathes (GEMINIS LATHES S.A.) is a Spanish manufacturer of heavy-duty, large-format CNC lathes and multi-process machining centers, headquartered in Elgoibar, Basque Country, with over 60 years of operating history despite a current mercantile inscription dating to 1994. Its product portfolio is organized into three families: the GTi horizontal lathe series (GT5i through GT11i, G2/G4 variants), capable of handling workpieces up to 150 tons; the GMi multiprocess/millturn series (GM5i, GM7i, GM9i), which enable complete turning, milling, boring, and grinding of complex parts up to 80 tons in a single setup; and the GRi railway maintenance line (GR3i-W vertical boring machine plus GR5i-A, GR5i-S, GR7i-S axle/wheel lathes). Underlying technology includes twin-drive headstocks with ±0.0005° C-axis positioning, roller-guide multiprocess columns, automation modules supporting up to 200-tool magazines and automatic head/tool change, and a proprietary Industry 4.0 stack (Smart Factory, Smart APSS, Smart HMI) that integrates sensor data, OEE, predictive maintenance, and CAD/CAM/ERP connectivity. Co-developments with TEKNIKER have produced the LASTORN laser cladding capability.

The business model is build-to-order, quote-based capital equipment sales complemented by a service revenue stream. Geminis does not publish list prices; each machine is engineered to customer specifications under multi-year contracts, with revenue recognized on hardware plus high-margin professional services (installation, CNC process support, operator training, after-sales maintenance, and retrofitting of legacy equipment). Go-to-market is a hybrid of direct sales from Spain for the Basque Country, Rioja, and Navarra, and an exclusive global distributor network across 30+ countries, supported by trade-fair presence at BIEMH, EMO, IMTS, Global Industrie, and InnoTrans. The customer base is enterprise and highly diversified across 10 verticals: railways, metallurgical/steel, power generation, oil and gas, marine, aerospace, pulp and paper, defense, general machining, and subcontract machining. Named reference customers include TALGO (railway maintenance) and MEKALERUN (precision machining subcontracting). The company holds ISO 9001, ISO 14001, ISO 14006 (eco-design), OHSAS 18001, and CE marking certifications.
