What Ernst Grob does
Ernst Grob AG is a Swiss family-owned manufacturer of specialized cold forming machine tools, founded in 1962 by Dr. Ernst Grob in Männedorf, Switzerland, and currently controlled by Daniel Dériaz Holding AG. The company builds dedicated machines and systems for chip-free cold forming of precision metal splines and gear-like geometries, organized around its proprietary Grob cold forming process — described by the company as a method found nowhere else in the world. The product portfolio spans nine standard machine lines (A9/A9T universal, C6 compact, C9/C9T, C9T-Helix, i9 internal forming, T12 large-format, R3 spinning, S8 slotting) plus customized special-purpose machines and interlinked production lines, complemented by an in-house tool library of 7,500+ profiles.
The underlying technology covers external cold forming, internal cold forming, intermittent forming, slotting and coining, and spinning, with proprietary kinematics that enable material strengths up to 1,500 N/mm² on solid parts and surface roughness of Ra 0.4 (N5). Revenue is generated through three streams: machine and system sales (hardware), contract manufacturing using in-house Grob processes, and integrated lifecycle services including development/co-engineering, toolmaking, factory overhauls, customer service, and used machine sales. Pricing is not publicly disclosed; all sales are consultation-based B2B engagements.
The go-to-market relies on a global network of exclusive country-level agencies and representatives covering more than 25 countries across Europe, the Americas, Asia, Africa, and Oceania, supplemented by a wholly-owned subsidiary in Beijing, Ernst Grob (Beijing) Machine Tool Co., Ltd. Primary customer segments are automotive OEMs and tier-1 suppliers (transmissions, drivetrains, EV/hybrid powertrains), mechanical engineering and industrial manufacturers, extruder manufacturers for plastics/pharma/food/battery production, and agricultural and construction machinery makers. The company holds ISO 9001:2015 certification (valid 2024-2027) and reports no public funding, no stock exchange listing, and 60+ years of continuous operation.
