Walker permanent chucks are manually operated. Made with powerful permanent ceramic and 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, Neodymium EDM Power Magnets

Fine Division Permanent Magnetic Chuck The Ceramax is the most widely used permanent magnetic chuck in the machine tool industry. Its patented design offers maximum holding power, ease of installation and operation. It is also extremely versatile. In addition to general toolroom grinding, the Ceramax is suitable for light milling and EDM applications. STANDARD FEATURES ° Solid construction top plate protects permanent magnetic pack from penetration of coolant * Provides stronger more rigid work surface « Maximum workholding surface ° Fine pole divisions for more uniform magnetic holding...

Super Accurate, Micro-pitch Permanent Magnetic Chucks for Precision Grinding Maximum grinding accuracy ■ Unique actuating mechanism elminates switching deformation • Uniform magnet force distribution over the entire working area Maximum grinding efficiency ■ Neodymium magnetic system generating 30% higher force compared to other micropitch chucks • Maximum workholding surface 100% active with no weak areas • Very low magnetic field allowing easy disposal of grinding swarf • Low height allowing maximum wheelhead clearance and ability The Neomicro2 chuck is ideal for reliable clamping of very...

Powerful Permanent Magnetic Chuck for Milling Double Neodymium magnet pack generates a powerful holding force onworkpieces 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...

Rotary Permanent Magnetic Chucks These chucks provide dependable magnetic holding for rotary surface grinding 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. Total Rear Rear Face Face Tapped Hole Hole Tap Height Pilot Dia.

Walker rectangular electromagnetic chucks for surface grinding and light milling LBP operate on DC voltage with the use of a Walker electromagnetic chuck controller. Interloc Holding power, with full, variable, and residual cycles for easy operation, is achieved with the use of Walker chuck controls.

Fine-Division LBP Electromagnetic Chucks Maximum workholding surface Fine pole division (.13") for more uniform magnetic holding of small parts Lowest height of any electric chuck for more wheel head clearance Solid brazed construction top plate protects coil from penetration of coolant; provides stronger, more stable work surface The LBP is an extremely 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...

Low Profile Interloc Chucks This 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. Size...

Walker electropermanent chucks are used in surface grinding, TurboMill 40B light-to-heavy milling and hard turning. Muitj Po|e Electropermanent chucks maintain holding power in the Rotary Chucks event of a power failure.

For Heavy Milling Operations Electropermanent magnetic chuck, (ALNiCo and Neodymium) 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 BUR-FR/BFR control unit / TM control Through drilling possible with use of riser blocks Minimum size of the usable workpiece: ■ Hold down clamps • Cable for current supply of the chuck: 3 m / USA provides Brad Harrison Connector with chuck and DC cable with purchase Controls available for worldwide operation.

MULTI POLE Rotary 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 work- pieces 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. Other sizes available upon TYPICAL HORIZONTAL (OR VERTICAL) INSTALLATION TO ffiS cSZoK"
