The clamping system with NdFeB high-energy magnets were optimised as per the latest magnet technology. Owing to the permanent electro-magnetic circuit of the AlNiCo/NdFeB magnet system, extremely high adhesion forces are generated. Short current impulses are used for magnetisation and demagnetisation.

For heavy milling of extremely large and strong workpieces. For large air gaps.

  • Minimum thickness of workpiece: 35 mm
  • Minimum size of workpiece: 150 x 150 sqmm
  • Nominal adhesion force: 170 N/sqcm


  • Optimised high-energy magnet system
  • Maximum possible physical adhesion forces
  • The magnet system with high depth effect also bridges larger air gaps
  • Complete surface is magnetically active, no “dead zones”
  • Solid mono-block design
  • “Real” pole distances N/S
  • Electro-permanent system for absolute safety in case of a power failure
  • Pole gap with wear-protected brass
  • 8 mm wearing capacity of the pole plate:
  • Grid threaded hole pattern for pole strips or movable pole shoes possible (M)
  • Clamping slot on both front faces
  • From lengths greater than 1000 mm with through holes for fixing as per the agreement
  • Robust and water-tight
  • Protection type IP 65
  • Suitable for connection with control device SAV 876.12
