Permanent chucks

Permanent magnetic chucks for grinding harness the power of permanent magnets to create sufficient clamping force necessary for grinding, polishing, assembly work and so on. They are currently produced almost exclusively with Neodymium (NdFeB) magnet system which ensures excellent clamping force. Switching on and off the chuck is done mechanically using a hex key. In the off state the magnetic field is enclosed within the body of the fixture while it is switched on is suitably directed through the pole plates to clamp workpieces.
