  • The massive, heavily ribbed cross-bed machine frame with traversing column and horizontal spindle is extremely rigid even under heaviest workpiece loads
  • The large work area allows machining of single workpieces with large surface areas or machining of several workpieces in one setup
  • A high-performance cooling system is included in the standard equipment of this series

Control

  • Grinding cycles for automatic face and groove grinding are accessible and editable via touchscreen
  • Preloaded ball screws and powerful servo-motors on Y and X ensure high precision and repeatability during grinding wheel feeds
  • An electronic hand-wheel for Y- and Z-axis simplifies setup and manual positioning 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

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

Hydraulics

  • Superior quiet operation and low heat build-up ensure optimum work results in continuous operations
  • The hydraulic linear table feed is infinitely variable, maintains a constant speed with smooth travel direction reversals
  • The external hydraulics unit with oil cooler ensures perfect temperature stability

Magnetic clamping plate

  • Large magnetic chucks for torsion-free clamping across the entire work surface are included in the standard equipment
  • The modern control also ensures reliable operation with firm holding forces and high-grade degaussing

  • 2-axis position indicator
  • electronic hand-wheel Y/Z axis
