The ElectroPermanent Mastermill Milling Chuck is a chuck with 50×50 mm square poles, a compact low design (only 51 mm high) and a nominal holding force of 170 N/cm2. The ElectroPermanent magnet has a practical offset (slot) around its entire perimeter for clamps and there is also enough space on the magnet to perform through clamping holes. Using pole extensions, the material can be machined from five (5) sides, drilled through, and uneven material can be machined as well.

When to choose the MPI ElectroPermanent Mastermill Milling Chuck:

The MPI ElectroPermanent Mastermill Milling Chuck is a versatile magnetic chuck for milling and drilling of both small and large workpieces. Using pole extensions, the material can be machined from five (5) sides, drilled through, and uneven material can be machined as well. For optimum holding force, the required workpiece thickness is at least 0.47 in.

Important parameters:

  • Application: Milling
  • Technology: Electropermanent
  • Chuck dimensions: from 12x20in
  • Holding force: 170 N/cm² / 246 lbs/cm²
  • Min. workpiece size: 50mm x 110mm x 20mm/2”x4.3”x0.787”
  • Recommended workpiece thickness: minimum 12mm/ 0.47”
  • Regrinding limit: 6mm / .236”
  • Pole size: 2 x 2 in
  • Poles: Square

Use:

  • machining of uneven parts up to five (5) sides
  • clamping of a wide range of workpiece sizes during milling
  • clamping of large forms, castings, blocks, structures, etc. during drilling operations
  • rough grinding of large parts
