High-Precision Cylindrical Grinding Machine for Inside and Outside Machining


  • Large machine bed in a heavy design accommodates workpieces with lengths up to 3000 mm and diameters up to 320 mm
  • Wide, precision-ground guideways ensure maximum accuracy across the entire workpiece length and accommodate high workpiece weights
  • The table features large dimensions and swivels in two directions - table movement via hand-wheel or automatically via linear hydraulic feed
  • The robust feed valve allows very precise micro-feed control on the X axis, including a user-adjustable dwell time at the end of the longitudinal table travel
  • Hydraulic ratchet feed simplifies exact X axis positioning, limited by an adjustable zero stop, and repeated feeds by the push of a button
  • The adjustable grinding spindle features superior bearings and provides for maximum precision and surface quality, plus extraordinary tool life and rigidity
  • The grinding spindle motor provides up to 7.5 kW power and is designed for continuous operation
  • The heavy-duty spindle head swivels 30° to the left and to the right; the work spindle head swivels 45°
  • Standard inside grinder for grinding parts with diameters up to 100 mm
  • Integrated rapid feed on Z axis with manual return
