For universal chucking of workpieces with high precision.

  • For main workpiece axis perpendicular to the pole pitch
  • For workpieces up to min. thickness x:
    4.5 mm with P = 13 mm
    6.0 mm with P = 18 mm
    8.5 mm with P = 25 mm
  • For flat workpieces min. a:
    25 mm x 25 mm with P = 13 mm
    32 mm x 32 mm with P = 18 mm
    45 mm x 45 mm with P = 25 mm

The magnetic force is generated by the permanent magnets which are magnetised and demagnetised with short current pulses. The block magnet features a sturdy design and a long service life. The pole pitch forms “true” N and S poles.

  • Solid pole plate with 13 mm, 18 mm or 25 mm transverse pole pitch
  • “True” N/S pole spacing
  • Switch-off using demagnetising cycle
  • Electro permanent magnetic system for absolute safety in case of power failure.
  • On request available with compressed air holes for P = 18/25 mm for easier removal of larger parts (adhesion)
  • High accuracy thanks to pole plates bolted in a narrow grid
  • Reinforced systems for high wear possible on request
  • 8 mm wear layer on the pole plate
  • Pole plate can be replaced when worn
  • Chucking slots on both face sides
  • Length over 1000 mm with through holes for fastening upon agreement or machine table
  • Robust and water-tight
  • Protection rating IP 65
