GROB WERKE

What GROB WERKE does

GROB-WERKE GmbH & Co. KG is a family-managed German manufacturer of CNC machining centers and production/automation systems, founded in 1926 and headquartered in Mindelheim, Germany. The company operates six production plants across Germany, Brazil, the USA, China, Italy, and India, supplemented by 13 sales-and-service subsidiaries, giving it a global footprint spanning ~9,600 employees and over 430,000 m² of production area. Its core product architecture is built around horizontal-spindle machining centers organized in modular G-module platforms (G300–G720), with specialized F-series machines for automotive frame structures and chassis parts, universal 5-axis and mill-turn centers, and dedicated electromobility production systems for e-motors, battery housings, and fuel cells.

The technology stack centers on proprietary in-house-designed motorized spindles, supported by diagnostic modules (GROB Spindle Diagnostics / GSD and Chip-in-Spindle Detection / SiS) and the Cosera Manufacturing Execution System. Revenue is generated primarily through capital-equipment sales (machining centers, spindles, automation cells) with secondary recurring streams from field service, training, spindle repair, and a refurbished-machines/buy-back program. GROB's primary customers are automotive OEMs and Tier-1 suppliers, with secondary exposure to aerospace & defence, mechanical engineering, die/mold, medical technology, energy, and semiconductors. Reported annual output is approximately €2.0 billion. Distribution is executed through direct enterprise field sales, the global subsidiary network, authorized commercial agencies (e.g., Produktionstechnik NRW), and regional sales agents.
