Neospark permanent magnetic chuck for electrical discharge machining

Magnetic chuck Neospark

When to choose a Neospark permanent magnetic chuck:

The Neospark permanent magnetic chuck is suitable for workpiece clamping during electrical discharge machining. The high holding force and fine pole pitch make it possible to clamp small and thin workpieces. Due to its very low structure, you do not lose any working area. Moreover, this chuck offers comfortable control from the top of the magnet, so it is possible to use the entire area of the submersion working tank of your EDM machine better.


  • Solid steel base with integrated control system
  • Efficient electrical discharge machining of hard materials due to the high holding force
  • Simple operation and maintenance
  • Waterproof design
  • Very low magnet height
  • Magnet switch on the upper plate for easy operation Double magnetic system with neodymium magnets
