Electric-Permanent Magnetic Chuck
Combines strong holding with reduced continuous power use. Safety interlock and workpiece contact area must be checked.
Magnetic workholding for flat parts, grinding, milling and quick workpiece release.
Magnetic Chucks
KORRETTO magnetic chucks are used to hold ferromagnetic workpieces on grinding machines, milling machines and magnetic workholding stations. The range includes permanent magnetic chucks, electromagnetic chucks, electro-permanent magnetic chucks, fine-pole magnetic chucks, sine magnetic chucks, circular magnetic chucks, vacuum chucks and related magnetic workholding accessories.
Permanent Magnetic Chuck
Provides magnetic holding without continuous electrical power.
Rectangular Electromagnetic Chuck
Uses electrical power to generate holding force. Power supply and safety control should be reviewed.
Fine Pole Permanent Magnetic Chuck
Fine pole spacing helps hold smaller or thinner ferromagnetic workpieces.
Sine Permanent Magnetic Chuck
Used when the workpiece must be held magnetically at a controlled angle.
Circular / Sector-Shaped Electromagnetic Chuck
Suitable for circular or special magnetic workholding layouts.
Vacuum Chuck
Used when magnetic clamping is not possible due to material type.
Permanent Magnet Lifter
A related magnetic accessory used for handling rather than machining clamping.

FAQ
What is a magnetic chuck used for?
A magnetic chuck is used to hold ferromagnetic workpieces by magnetic force, commonly for grinding, milling, inspection and flat workholding applications.
What is the difference between permanent and electromagnetic chucks?
A permanent magnetic chuck uses permanent magnets and does not require continuous power. An electromagnetic chuck uses electricity to generate magnetic holding force.
What is an electro-permanent magnetic chuck?
An electro-permanent magnetic chuck uses electrical power to switch the magnetic state, but does not require continuous power during holding.
Are magnetic chucks suitable for aluminum or non-magnetic materials?
No, standard magnetic chucks require ferromagnetic workpieces. For aluminum or non-magnetic materials, vacuum chucks, vises or other fixtures should be reviewed.
What information is needed for selection?
Provide workpiece material, size, contact area, thickness, machining process, required holding force and machine type.
