Magnetic chuck for milling Mastermill 70


When to choose a Mastermill 70 SQ electropermanent magnetic chuck:

If you are looking for a versatile magnetic chuck for heavy duty milling and drilling of medium-sized and large workpieces, draw you attention to Mastermill 70SQ chuck. Compared to the basic Mastermill SQ series, the larger 70x70 mm magnetic poles offer higher performance in combination with pole extensions for effective claming of uneven workpieces or 5-side machining in a single setup. For optimum holding force, the required workpiece thickness is at least 17 mm. Thanks to the combination of steel/stainless steel materials on the top plate, this series of magnetic clamping chucks is suitable for dry or MQL machining processes.

Advantages:

  • „Sandwich“ construction of the magnet with upper top plate guarantees the absolute waterproofness and long service life
  • Possibility to machine the workpiece from 5 sides, drill through or machine uneven workpieces
  • The stop blocks can be moved freely to any side
  • Slot round the entire perimeter – for easy attachment to the machine table
  • Possibility to perform through going holes for additional fixing to table
  • 6 m-long armoured power supply cable
  • Possibility to connect a set of several magnets to a single control unit
  • Available also in custom-made dimensions
