ELECTRO-PERMANENT MILLING SYSTEM
Electro-permanent milling system allows milling, boring and drilling operations on pieces of various shapes and sizes, reducing clamping times and obtaining high precision.
The magnetic chuck for milling operations, thanks to the electro-permanent technology, does not overheat, does not deform, does not suffer from interruptions in the power supply.
It can be activated in a fraction of a second and with a single input of energy, generating a homogeneous, stable and permanent force field. The work-piece remains safely clamped even after the control unit has been disconnected.

ELECTRO-PERMANENT CHUCK FOR REMOVAL THROUGH MILLING ON MEDIUM-LOW THICKNESS PIECES
It is the most versatile magnetic chuck in the range. Generating force on few millimetres, it enables small and medium-sized workpieces with reduced thicknesses to be processed. The dense pole pitch allows effective adaptation to a wide range of designs.
It can be used with fixed and mobile extensions, for processing on 5-axis machines, with both unfinished and finished work-pieces.

MFP-A1-L30
ELECTRO-PERMANENT CHUCK FOR REMOVAL THROUGH MILLING ON MEDIUM-LOW THICKNESS WORK-PIECES WITH IRREGULAR OUTLINE
This is the classic parallel pole chuck for milling applications, optimised for maximum versatility, specific strength and a wide choice of pole extensions (fixed, flexible, upper plates). It gives its best with medium-low thickness work-pieces, of complex and irregular outline, thanks to the ease in obtaining the correct balance of North and South polarity.
MFP-A1-L08
ELECTRO-PERMANENT CHUCK FOR REMOVAL THROUGH MILLING OF SMALL AND THIN-WALLED WORK-PIECES.
It is the only real solution on the market for milling small and thin parts, where other electro-permanent solutions show their limitations. The very fine pitch allows optimal flux control on low thicknesses, thus ensuring the best possible clamping force and the elimination of problems related to chip evacuation. The all-metal clamping surface provides stability, precision and durability; the top/upper plate is also replaceable, allowing easy repairs in case of accidental damage or special needs.
ACCESSORIES
Fixed extensions
Fixed pole extensions, available in various sizes and equipped with screws, ensure a precise support of the work-piece on the surface of the magnetic module. This makes it perfect for machining smooth or machined work-pieces. They significantly improve the operating space for the machine, for example in the case of contouring and through-hole drilling operations. The extension is designed to ensure that the flux transmission from the chuck plate to the clamping surface, takes place with minimum loss, ensuring the safe clamping even of more complex work-pieces.

Flexible extensions
The flexible pole extensions, consisting of a lower part fixed to the poles and a sliding upper part, allow the height adjustment of the working surface of the chuck compensating for any deformation of the work-piece (automatic thickness adjustment). When, for example, a raw and deformed (bent) plate has to be levelled, the magnetic clamping force would tend to straighten it and consequently, once the work has been completed and the slab plate demagnetised, there would be an elastic return effect, that would not allow the elimination of the deformation. By means of flexible extensions it is possible to adapt to the deformation of the plate, to clamp it during the first levelling phase and, once rotated for the second machining, to obtain an excellent flat surface. It is important for the plate to always rest on at least three suitably established fixed points, which will act as a constant reference point for the work surface.

Pole bars
The pole bars are fixed multi-pole extensions allowing the rapid creation of support and reference mounts, side stops and the use of centring pins. They are widely profilable and quickly replaceable, available in modular formats to be assembled according to the clamping requirements.

Pole plates
When the clamping surface requires contouring, or when the chuck needs a chip wear protection or a pole pitch change (parallel pole magnets), the square or parallel pole plates are able to provide an additional support. These plates are accessories available in different sizes and formats for a better adaptability to standard magnetic chucks, but can also be produced in special sizes.
