Grinding Chucks

LBP Series

The Walker LBP fine division electromagnetic chuck is extremely versatile and suitable for both grinding and EDM operations. Its variable holding power allows you to hold the workpiece accurately so that there is just enough force to hold the workpiece in place. The magnetic surface pattern allows for simple and inexpensive tooling designs to hold intricately shaped workpieces. It simplifies complicated setups with accurate repeatability. Sizes range from 4″x8″ to 16″x32″. Contact the factory for detailed specs and pricing.

• Powerful holding over the entire chuck surface
• Fine pole divisions – for more uniform magnetic holding of small parts
• Lowest height of any electric chuck – for added clearance on larger workpieces
• Supplied with (2) hold-down clamps
• Magnetic field does not affect EDM operation
• Recommended Controls. For best results, Walker SMART Automatic Release
• Controls are recommended with all LBP design chucks.

NEOMAX™ C-2 Series

Fine division permanent chuck suitable for both grinding and EDM operations. The Walker Neomax™ C-2 is the most widely accepted permanent magnetic chuck in the machine tool industry. In addition to its ease of installation and operation, this Walker design offers the highest holding power available on the market. It simplifies complicated setups with accurate repeatability.

• Manufactured with high-power neodymium magnets
• Full magnetic surface to all edges – powerful holding over entire chuck surface
• Fine pole divisions – for more uniform magnetic holding of small parts
• Solid construction top plate – protects the permanent magnetic pack from penetration of EDM fluids. Provides a stronger and more rigid work surface
• Lowest height of any permanent chuck – for added clearance on larger workpieces
• Supplied with (2) hold-down clamps
• Magnetic field does not affect EDM operation
• Milling finish on sides and ends
• Angled backrest and end-stop

INTERLOC™ Series

This universal workholding chuck offers maximum effective holding on the widest range of workpiece shapes and sizes. Its effectiveness is considerably enhanced by the new low-profile feature, which adds more headroom under the wheel. Only 3 1/2″ in height, this low-profile Interloc is a full 1 1/2″ less than competitive units of the same type. This savings in height permits greater flexibility with added headroom under the wheel to position the work or handle bulkier pieces. This results in savings in set-up time and added productivity. It also reduces the chuck weight by 30% or more. The low profile is achieved with no loss of strength, precision, or holding power. With the unique Walker Interloc design, more than 75% of the chuck’s surface is major north or south poles, making it easier to locate workpieces without concern for locating poles. There is no wear loss due to the shallower polarity pattern in the replaceable top plate.

• Only 3.5” in height, this low profile design allows for more headroom under the grinding wheel
• Replaceable top plate
• 75% of chuck surface is major north or south poles
• Lower profile height does not affect wear life after regrinding

NEOMICRO-2™ Series

Permanent magnetic micro pitch design chucks that are ideal for reliable clamping of very thin and small components for precision grinding. It holds large workpieces as well.

The Neomicro², is new and improved, replacing the Neomicro. This type of chuck is designed to reliably hold a large range of workpiece sizes, from very small and thin up to large, for precision grinding jobs.

• Unique actuating mechanism eliminates switching deformation
• Uniform magnet force distribution over the entire working area
• Neodymium magnetic system generating 30 % higher force compared to other micro pitch chucks
• Maximum workholding surface 100% active with no weak areas
• Very low magnetic field allowing easy disposal of grinding debris
• Low height allowing maximum wheel head clearance and ability to use the Neomicro on top of another chuck

TBP Electromagnetic Series

These transverse bar pole chucks are specially designed for smaller, thinner workpieces and tool steel. The magnetic poles and coils run across the chuck, creating more pole area. This chuck, being special in design, offers superb holding power, but because they are custom-made, we would only recommend them when careful investigation has shown that one of our standard chucks will not fit the application. Selection of this design should only be made with the assistance of our Engineering Department. Model Smart Controls are recommended for all Walker Electromagnetic Chucks.
