10GOOD REASONS FOR CHOOSING
THE ELECTRO - PERMANENT SYSTEM
1 - No energy consumption: the chuck absorbs power only for a few seconds during the magnetizing and de-magnetizing
phases.
2 - Always safe: if during the working plase current is cut out, the chuck remains magnetized.
3 - Immediate work loading/unloading piece: only a few seconds for loading/unloading the piece from its working position.
4 - Simple and practical: very simple commands from the pushbutton panel.
5 - Extremely accurate machining: the fixing force is electronically proportioned to the machining at hand by precisely
adjusting the magnetic power.
6 - Perfect clamping: since it is uniformly distributed along the surface, it allows a finishing quality without deformations.
7 - Totaly free working surface: the working face are free and clear of neutral points used for mechanical fixing.
8 - Flexibility: prompt, since the discharged chuck is immediately ready to accept a new piece, even of a different size.
9 - Reduction of others costs: all structures and other dedicated casings are eliminated even as a traditional cost items.
10 - Machine full exploitation: during machining, all available working surface is used.

- Fine grinding within reach
Thanks to its solid construction and the evenly distributed magnetic force, you can grind accurately without deformation.
- Aesthetic, highly accurate design
The construction not only functions as a unity; it has expressly been designed like that. Monoblock body, top plate and steel frame are mechanically and magnetically bonded, and offer an exceptional stability and precision.
- High degree of reliability and efficiency
The entire width of the Neomicro2 can be loaded, whilst maintaining a high holding force. The system power also allows for holding uneven work pieces.
- High magnetic clamping force
The twin Neodymium magnetic system generates a force of 130 N/cm2; a staggering 60% more than the average micro pitch chuck.
- Low remanence
Residual magnetism is negligible, enabling you to easily remove your work piece from the holding surface, once the chuck is deactivated.

Permanent magnet, PL model
Its main feature is lack of connection to the power supply.
Inside, there are permanent magnets whose magnetization is guaranteed for life. They lack maintenance, only regular cleaning must be performed, removing iron captured, because, if they build up, they can "short-circuit" the magnetic force.
They are installed hanging on the conveyor belt, parallel to it, and keeping a distance above it, according to its features.

Chucks are widely used holding tools especially in the metal working industry. The most common types work on the principle of magnetism where the magnetism is, depending on the type, created by permanent magnets, electromagnets or a combination of both. The use of magnetic chucks for holding pieces of work made of ferromagnetic materials has many advantages over more
conventional clamping methods. Rapid work positioning since the chuck is simply switched on and off by means of a single handle. Besides the fixed handle, all of
Bakker Magnetics permanent magnetic chucks can be supplied with a detachable handle using an allen key. The ability to switch the magnetic force on and off allows work to be positioned easily and accurately, the choice of the type of chuck being largely determined by the shape and size of the piece of work.

At clamp (magnetized)
Energize electromagnet coil for 0.5 second.
Pole of Alnico magnet is inverted.
Neodymium magnet and Alnico magnet become homopolar.
Magnet core turns to a powerful magnet to adhere
the workpiece.
At unclamp (Demagnetized)
Energize electromagnet coil for 0.5 second.
Pole of Alnico magnet is inverted.
Magnet line of Neodymium magnet and Alnico
magnet does not go out from the surface of magnet
core. Thus it unclamps the workpiece.

The Alpha Mill Round Milling Chuck is a Permanent-Electro Magnetic System—it requires electricity for just a fraction of a second to polarize the magnets contained within the chuck.
No electricity is required to maintain the magnetism and is therefore "failsafe." The Alpha Mill Round provides significant magnetic clamp force for milling, drilling, tapping and other machining processes, while managing the magnetic flux.
Perfect for :
- Job Shops, Mold Shops or Production Machining
- Squaring Up
- Five Face Machining
- Thru Machining
- Pallet Applications
- Large Plate or block Applications

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 head room under the wheel. Only 3 1/2" in height, this new low profile interloc is 1 1/8" shallower than the conventional Walker Interloc and a full 1 1/2" less than competitive units of the same type. This savings in height permits greater flexibility with added head room 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.
