Predominantly for precise grinding of small to large workpieces on rotary table and round grinding machines. Owing to the ring pole pitch, also suitable for allocation with multiple mass-produced parts that are not stored centrally.

  • Uniform adhesion force distribution at the circumference due to the ring pole pitch. Therefore, suitable for thin and flat parts (saw blades and similar)
  • Multiple allocation for the pitch circle diameter is possible
  • For workpieces up to minimum thickness x:
    2 mm for P = 4.5 mm
    4 mm for P = 9.0 mm
    8 mm for P = 18 mm
  • For flat workpieces, minimum size 45 mm x 45 mm
  • “Gap-free” pole pitch produced
  • Uniformly strong magnetic field
  • Solid pole plate
  • Switch-off via demagnetisation cycle
  • Electro-permanent system for absolute safety in case of a power failure
  • High accuracy due to pole plate screw joint in the narrow grid
  • Pole plate with wear-protected brass
  • Pole plate can be replaced after it is worn out
  • 8 mm wearing capacity of the pole plate
  • Protection type IP 65
  • Suitable for connection with control device type 876.12
  • Can be delivered with a flange on request (see SAV 248.90 to 248.94, section 1)
