Rohm Spanntechnik AG

What Rohm Spanntechnik AG does

RÖHM Spanntechnik AG (operating as RÖHM GmbH Sontheim in Germany) is a privately held German manufacturer of precision clamping and gripping technology (Spanntechnik und Greiftechnik) for CNC machine tools, founded in 1900 and headquartered in Sontheim/Brenz, Germany. The company offers more than 7,000 standard products organized into three solution categories: Standard products (drill chucks, lathe and power chucks, machine vises, live centers, face drivers, grippers, cylinders, steady rests, mandrels, collet chucks, and HSK/SK tool clamping systems), Individual customized solutions developed for special customer requirements, and System solutions combining multiple RÖHM products into complete machining cells. The technology flagship is iJaw, the world's first sensor-integrated clamping jaw, which measures clamping force at the workpiece in real time and transmits data via IO-Link Wireless to an edge-compute control cabinet and a mobile application for process monitoring, anomaly detection, and predictive maintenance.

RÖHM generates revenue primarily through direct hardware sales of standard and custom workholding products, supported by after-sales service, repair, and spare parts. The company also sells the integrated iJaw automation package, which combines the sensor jaw, the iJaw Connect control cabinet, the iJaw Mobile app, and integration services for cobot-based automated loading/unloading. Pricing is quote-based and not publicly disclosed. Go-to-market is enterprise field sales with dedicated sales and service staff available globally via phone, video, and email, complemented by wholly-owned subsidiaries in France (RÖHM S.A.R.L.), Italy (RÖHM Italia SRL), and Spain/Iberia (RÖHM Ibérica S.A.), an e-procurement platform (Onventis), an 8-language website, active social media (Facebook, LinkedIn, YouTube/RoehmTV), a newsletter, and participation in industry trade shows such as EMO Hannover.

The company serves the automotive, aerospace, rail vehicle, defense, general engineering, microtechnology (including watchmaking and medical), energy, and industrial/trade verticals, with named customers including IWC Schaffhausen (using RÖHM power clamping indexing chucks on KERN Micro machining centers for watch platine production) and Hellmerich Precision Components. RÖHM maintains technology partnerships with leading machine tool builders — GROB, HERMLE, INDEX, and WFL — for live iJaw demonstrations, and a co-development partnership with WESA GmbH for a coolant-pressure-actuated revolver steady rest. The company has received the Best of Industry Award 2022 and the Industrie 4.0 Award 2023 for the iJaw platform.
