  • The cast-iron machine frame features superior rigidity and torsional strength, precision guideways and excellent machining quality
  • All guideways are lubricated reliably via a central lubrication system
  • The workspace is protected by an easily accessible enclosure
  • A powerful coolant pump is combined with a vacuum exhaust unit to clear grinding dust and aerosol during machining operations

Grinding spindle

  • Large grinding spindle, dynamically balanced, completely sealed with permanent lubrication
  • Preloaded precision-bearings ensure maximum grinding performance and high reliability over many production hours


  • The high-quality preloaded ball screw and a powerful servo-motor ensure high precision and repeatability of positioning on the Y -axis
  • The machine features an electronic hand-wheel for configuration tasks and manual movement of the grinding spindle
  • If set to Auto mode, the user-defined roughing and finishing parameters, number of spark-out strokes, and return to zero are automatically processed


  • Superior quiet operation and low heat build-up ensure optimum work results in continuous operations
  • Hydraulically operated linear table movement, infinitely variable, high consistency, and soft reversal of direction
  • The external hydraulics unit with oil cooler ensures perfect temperature stability

Magnetic clamping plate

  • Large magnetic chuck allows for torsion-free clamping and is included in standard equipment
  • The control unit is integrated into the electric system to simplify operation, allowing quick clamping and degaussing for maximum production efficiency
