  • The heavy cast-iron machine frame provides excellent rigidity and torsional strength, and is equipped with dual V-guides for cross travel and combined V-guides and boxways for linear motion
  • A large work area and high table load capacity allow machining of larger, heavy workpieces with highest precision
  • Superior quiet operation and low heat build-up ensure optimum work results in continuous operations
  • C models feature manual grinding-wheel feeds

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

  • 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
