Usage:

A strong magnetic field is the special feature of our circular magnets. The magnetic force is generated by the permanent magnets which are magnetised and demagnetised with short current pulses.

Primarily for precise grinding of small to large workpieces on rotary table and cylindrical grinding machines. Also suitable for turning applications.

  • Same pole pitch on the circumference, therefore suitable for ring-shaped workpieces
  • For workpieces up to min. width equivalent to 35 % pole pitch on the pitch circle diameter
  • Also for thin rings
Model:
  • Solid pole plate
  • Switch-off using demagnetising cycle
  • Electro permanent magnetic system for absolute safety in case of power failure
  • High accuracy thanks to pole plates bolted in a narrow grid
  • Pole plate with brass, wear-protected
  • Pole plate can be replaced when worn
  • The radial pole positioning is particularly suitable for using pole raisers. This prerequisite is absolutely required for the runout of the tool or the grinding wheel in case of
  • 3-sides machining. Version with T-slots (T) as per DIN 650-10H10 are available for this
  • 8 mm wear layer on the pole plate
  • Protection rating IP 65
  • Available with flange on request (see SAV 248.90 to 248.94, chapter 1.2.1)
