Clamping technology specialist since 1909
RÖHM GmbH, headquartered in Sontheim an der Brenz, is a manufacturer of clamping and gripping devices founded in 1909, with production sites in Sontheim, Dillingen an der Donau and St. Georgen. The company develops, designs and manufactures drill chucks, lathe chucks, face plates, power chucks, vises, centers, face drivers, steady rests, mandrels, collet chucks, cylinders, grippers, swivel units and tool clamping systems to SK and HSK standards. More than half of the products are custom special clamping devices; as a system supplier for turning and milling, the standard range comprises more than 7,000 items. Production is predominantly from steel and cast steel; at the Dillingen site, on portal turning and milling machines, workpieces up to 4 m in diameter and 25 t in weight are machined. The products are used, among others, in the automotive industry, aerospace, rail technology, energy technology, medical technology and in the machining of the smallest micro-components. RÖHM employs around 900 staff and delivers worldwide to more than 50 countries.
