Product Description

This series of surface grinders processes large and heavy workpieces with tolerances as required for precision surface grinding or for the preparatory processing step of lapping or polishing. The machine frame is designed in a cross-bed design with a movable column. This construction enables a long table guidance and thus the optimal introduction of weight force over the entire work area. The ability to switch between automatic or manual operation extends the scope for sample production, repair and training.

  • Moving column design for maximum stability
  • Enclosed working space
  • Siemens smart line PLC control with grinding cycles
  • NC controlled Y-/Z-axes driven by servo motors
  • User friendly HMI with touchscreen
  • Electronic hand wheel for Y-/Z-axe

    Product Details

    Surface Grinding Machine

    • 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
    • The workspace is protected by an easily accessible enclosure
    • 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

    • Extremely quiet operation and minimal heat build-up for optimum work results under continuous operating conditions
    • The hydraulic linear table feed is infinitely variable, maintains a constant speed with smooth travel direction reversals
    • External hydraulic unit with oil cooler unit 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
