About Ke-Ma-Tec

Ke-Ma-Tec GmbH (Ketterer-Maschinen-Technologie) in Bad Dürrheim continues the decades-long trade partnerships and engineering of the former Seibold + Ketterer GmbH and Ketterer Maschinenbau GmbH. The company manufactures and sells modular measuring and testing devices for runout, axial runout, angle, length and diameter inspections as well as T-slot plates and accessories for lathes and sliding-headstock automatic lathes (including Tornos-Bechler). In addition, the company offers CNC and conventional machining: 5-axis milling, turning, surface and cylindrical grinding of prototypes and small series in steel, aluminium, stainless steel, non-ferrous metals and plastics. The portfolio is complemented by engineering with FEA analyses, software development, prototype construction, assembly of assemblies up to 3000 x 3000 mm on a granite plate, as well as repair service for measuring devices and spindle assemblies. As an authorized specialist distributor of Mitutoyo, the company also sells measuring devices and offers technical seminars and rental equipment. Customers come predominantly from machine tool manufacturing, mechanical engineering and testing and metrology.
