Used Kellenberger Grinding Machines for Sale 23

Kellenberger has been synonymous with precision universal cylindrical grinding since its founding in Switzerland, and its machines remain the benchmark against which other universal grinders are measured in applications where tolerances are measured in single-digit micrometres.

The universal grinding concept — combining external, internal, face, and taper grinding in one machine — reduces the number of setups required for complex components. A part that might require three separate machines can be completed in a single clamping on a Kellenberger universal, eliminating inter-machine transfer errors and the associated re-clamping uncertainties.

The VITA and KEL series represent current and recent production. These machines use hydrostatic guides and direct-drive spindle technology, with CNC control providing automatic cycle execution. Earlier models — the UR series in particular — established the brand's reputation and remain highly sought on the used market for their exceptional rigidity and ease of manual operation by skilled toolmakers.

Thermal management is engineered into the machine structure. Temperature-controlled coolant systems and thermally symmetric casting designs minimise dimensional drift during extended grinding cycles. This matters most during close-tolerance production runs where a few micrometres of thermal growth can push parts out of specification.

Swiss build quality means used Kellenberger machines often retain geometric accuracy far longer than competitors of similar age and operating hours. However, this longevity also means the used market includes machines spanning several decades of production — verify the machine generation, available spare parts supply, and CNC control vintage before committing to purchase.

When browsing used Kellenberger grinders on Exapro, request geometric test certificates covering roundness, cylindricity, and surface finish capability, verify spindle bearing condition through runout measurement and temperature monitoring, and confirm software compatibility with your CAM system if you intend to use offline programming rather than manual cycle setup.
