Magnetic clamping technology \ Round permanent magnetic chuck
Permanent magnet round chuck FERROMAX
With parallel pole pitch

Application: ƒ Centre drilling is possible at the centre, see table
suitable for clamping large and small workpieces. for use on lathes and grinding
machines, dividing and tracer divider devices. Advantage:
ƒ Compact design and hence low weight
Execution: ƒ nominal adhesive force 150 N/cm , from Ø 200 mm, nominal adhesive force
2
ƒ High-performance neodymium magnetic system with low magnetic field height 100 N/cm 2
of 8 mm for workpieces from 10 mm upwards
ƒ Integrated concentric grooves simplify workpiece centring Notes:
Available on request with flange and up to 500 mm diameter
ƒ Die clamping surfaces can be machined down to a depth of 6 mm (wear of pole
surface)
