Mastermill variable electro-permanent magnetic chucks


When to choose a Mastermill electropermanent magnetic chuck:

If you are looking for a versatile magnetic chuck for milling and drilling of small and large workpieces, then a Mastermill chuck is the right choice. Using pole extensions, the material can be machined from 5 sides, drilled through, and uneven material can be machined as well. For optimum holding force, the required workpiece thickness is at least 12 mm. Standard version with top plate in steel/stainless steel combination is also suitable for dry or MQL machining.

Advantages:

  • Possibility to machine the workpiece from 5 sides, drill through or machine uneven workpieces
  • The stop blocks can be moved freely to any side
  • Slot round the entire perimeter – for easy attachment to the machine table
  • Possibility to perform through going holes for additional fixing to table
  • Low compact design
  • 6 m-long armoured power supply cable
  • Possibility to connect a set of several magnets to a single control unit
  • Top plate in steel/stainless steel combination guarantees high mechanical durability and thermal resistence.
