alker permanent chucks are manually operated. Made with powerful permanent rare earth (NEO) magnet materials, these chucks can hold a wide range of workpieces without transfering heat into the material. The Walker Permanent chuck allows for holding workpieces during both surface and ID/OD grinding, as well as light milling. EDM and turning applications. • Neomicro • Neomill • Ferromax • Neostar • Neogrip • Neodymium EDM Power Magnets

T he C2 magnetic chuck is a high powered permanent magnetic chuck using Neodymium (rare earth) magnet material. This magnet is an extremely versatile magnetic chuck that can be used for grinding, sinker EDM and light milling applications. Standard Features • Solid steel and stainless steel fine pole top plate • Steel body milled on all sides • Powerful Neodymium magnet material • Attached handle with 1800 activation • Uniform holding power

T he Neomicro chuck is ideal for reliable clamping of very thin and small components for precision grinding. It holds large workpieces as well. Super Accurate, Micropitch Permanent Magnetic Chucks for Precision Grinding Maximum Grinding Accuracy • Unique actuating mechanism elminates switching deformation • Uniform magnet force distribution over entire working area Maximum Grinding Efficiency • Neodymium magnetic system generating 30% higher force compared to other micropitch chucks • Maximum workholding • Very low magnetic field allowing easy disposal of grinding swarf • Low height...

Permanent Radial Pole Chuck Neostar chucks with Neodynium (rare earth) magnet material are designed for holding rings and bearing races, as well as solid rounds. This chuck comes standard without center hole. An optional through hole can be provided upon request.

Rotary Permanent Magnetic Chucks T hese chucks provide dependable magnetic holding for rotary surface grinding and light turning applications The top plate is magnetic with each pole individually magnetized by powerful ceramic permanent magnets, so electrical controls and collector rings are not required. Frequent magnet polarity changes result in low magnet field to prevent magnetization of tool bits.

alker rectangular electromagnetic chucks for surface grinding and EDM operate on DC voltage with the use of a Walker electromagnetic chuck controller. Full, variable, and residual cycles for easy operations, is achieved with the use of Walker chuck controls.

LBPFine-Division LBP Electromagnetic Chucks Maximum workholding surface Fine pole Division for more uniform magnetic holding of small parts Lowest height for maximum clearance Solid brazed construction top plate protects coil from penetration of coolant; provides stronger, more stable work surface. The LBP is an extemely versatile chuck. Its variable holding power permits easy flat grinding (without shimming) of workpieces that do not have one true surface. The magnetic surface pattern allows for simple and inexpensive tooling designs to hold intricate shaped workpieces. Suitable for EDM...

gjpflINTERLOC rhis universal workholding chuck offers maximum effective holding on the widest range of workpiece shapes and sizes. With the unique interloc design, more than 75% of the chuck’s surface is major north and south poles, making it easier to locate workpieces without concern for locating poles. This design has made these chucks useful in both grinding and light milling applications. At 3.5” in height, it is a full 1.5” lower than the conventional grid style chuck, allowing for more head room. The lower profile height does not affect wear life after regrinding. Transverse Bar Pole...

ELECTROPERMANENT Walker electropermanent chucks are used in surface grinding, light-to-heavy milling and hard turning. Electropermanent chucks maintain holding in the event of a power failure. • TurboMill 40B • Multi Pole • Rotary Chu

For Heavy Milling Operations • Electropermanent magnetic chuck, (ALNiCo and Neodynium) • Reduce set-up time and increase available machine time • Helps to dampen vibrations, resulting in longer tool life • Allows single set-up machining with 5-sided accessibility • Operation through a Walker TM Control • Through drilling possible with use of riser blocks Minimum size of the usable workpiece • Thickness: 200 mm • Length: 170 mm Accessories • Backrest and endstop • Hold down clamps • DC cable supplied with controller *Controls available for worldwide operation, See controls page.

MULTI POLERotary Electromagnetic and Electropermanent Chucks Rotary electromagnetic and electropermanent chucks are made in radial pole multi-coil design for use in hard turning and free state grinding. The radial pole design is recommended for holding circular workpieces such as rings and discs. Most radial pole chucks come with t-slots, but tapped holes are also available for mounting tooling. The smaller chucks have four or six poles, while the larger chucks use a ten or twelve pole design.
