EFP electro-permanent magnetic clamping plates with a fine pole division combine the advantages of permanent and electro-magnetic chucks. The particle board does not heat up during long chip times, has a very controlled magnetic field and offers the possibility of holding force control and demagnetization. EFP magnetic chucks designed for grinding and eroding the highest precision even on small workpieces. They impress with uniform holding force over the entire gripping range.

Structure :

  • Electromagnetic system, steel body+pole
  • transverse or longitudinal pole pitch 1+3mm
  • Holding power 100 N/cm2
  • Magnetic field height approx 4mm
  • Pole plate wearing limit 7mm
  • Voltage 210V impulse
  • protection class IP 67



High-precision electro-permanent chipboard for grinding small, thin workpieces

The standard package includes 3m connection cable and a long and a short side stop bar.  Matching pole-reversal devices type ST 211 GR are also available with us.






EFP magnetic clamping plates can be used on most built-in Pole Reversal devices in European grinders
