Neodymium permanent magnet magnetic chuck Neospark

permanent magnetfor grindingfor EDM

The Neospark permanent magnetic chuck is designed for electrical discharge machining (EDM) to clamp small and thin workpieces with high holding force and a very fine pole pitch. It features a very low structural height and convenient top-side control for optimal use of the EDM machine's submersion tank.

Advantages

• Solid steel base with integrated switching mechanism
• High holding force enables efficient EDM of hard materials
• Simple operation and low maintenance
• Waterproof construction suitable for immersion in dielectric liquid
• Very low magnet height preserves the machine working area
• Top-plate magnet switch; double magnetic system with neodymium magnets

Detailed description

• Primarily designed for electrical discharge machining (EDM) and also suitable for precise surface grinding of small workpieces.
• Double magnetic system and fine pole pitch provide stable clamping for small and thin parts.
• Operation from the upper side of the chuck and minimal maintenance requirements simplify setup and handling.
