Kellenberger — Swiss manufacturer of high-precision cylindrical grinding machines
Kellenberger & Co. AG is a Swiss manufacturer recognized for its universal cylindrical grinding machines and high-precision grinding machines, a member of the United Grinding group — the same group as Studer. Its grinding spindles and motorized spindles, integrated on the Kel-Varia, Kel-Vista and R600 ranges, are designed for high-precision grinding in sectors such as automotive, aerospace and demanding subcontracting.
Maintaining these assemblies requires in-depth knowledge of their architecture as well as appropriate inspection equipment. This is precisely what Brochexpress has been providing for more than 30 years, from our sites in Beaurepaire (France) and Lussery-Villars (Switzerland).
