          During camshaft grinding, the grinding points change position due to the
          altering meshing conditions. The lubricoolant must therefore be supplied in a
          targeted and  effective manner. We thus supply your grinding  process via an                                           For the grinding of a bearing cage, our nozzle experts designed a special solution
          adapted needle nozzle (top nozzle). The nozzle components are equipped with                                            for optimum process cooling. A particular challenge was posed by the very confined
          wear protection, enabling a longer service life.
