KEL-VERA

Kellenberger KEL-VERA an innovative, compact, precision cylindrical grinding machine developed with a lower table for ease of loading any kind of component up to 400 mm in length. New, very rigid, hydrostatic guideways provide the basis for higher performance and dynamics in the X and Z axes, enabling significantly enhanced productivity and precision of unround components.. Three construction variants, Universal, Universal for Flanged components and Production are available each with various wheelhead options depending upon the model chosen. Ideal for auto loading applications the Kel-VERA has Loading cell, Palette loading, Portal loader or Robot loading cell options. Distance between centers up to 400 mm, height of centers 175 to 250 mm, weight of workpieces up to 250 kg.
