M A G N E T IC WORKHOLDING Permanent / Electromagnetic / Electropermanent / Rotary / Controls The magnetic chuck was invented by Oakley S. Walker in 1896. Walker manufactures rectangular and rotary chucks worldwide for the purpose of grinding, milling and hard turning. Magnetic workholding chucks are manufactured in Permanent, Electromagnetic and Electropermanent styles. www.walkermagnet.com

Powerful Permanent Magnetic Chuck for Milling Double Neodymium magnet pack generates a powerful holding force on workpieces with an uneven or rough contact surface Low magnetic field, concentrated over the top plate without stray fields. No chip contamination of workpiece surface and cutting tool Transverse, close pole division of 11 mm of steel and 4 mm of brass allows optimal holding of workpieces only 26 mm long and 6 mm thick. The top plate can be drilled and tapped to accommodate pins, pegs or other clamping aids Vibrations are dampened, contributing to machining accuracy Nominal holding...

Permanent Magnetic Chucks for EDM and Precision Grinding Low profile (height) of only 35 mm (1.37"). The Neospark chuck can be put on a pallet without creating weight and height problems, both in manual and robotic pallet changing systems Excellent holding force with micro-pole pitch allows holding of very small Height of the magnetic field being just 6 mm (.23") and the absence of stray magnetic fields allow EDM operations close to the chuck surface The smooth and flush faces of the chuck lower "contamination sensitivity" to EDM particles allowing easy cleaning and adding to the overall accuracy Usable...

Fine Division Permanent Magnetic Chucks In operation, the workpiece is held down on the Erofine with a very low magnetic field (3 mm). There is no influence on the spark erosion process and no particles adhere to the workpiece. Erofine is also suitable for high precision grinding. Clamping small and thin work- pieces is very difficult; the special construction of the Erofine chuck will reduce these problems. Unit Features Every (6 mm) narrow steel pole in the Walker Erofine magnetic chuck is supported by a set of permanent magnets on both sides. These are the same magnets that Walker uses in their...
