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.

Magnetic chuck plate without grid

Often a power magnetic chuck is inadequate for machining with
little removals.
The magnetic field performs only when the flux is concentrated on
the piece to be held, If the magnetic power, exceeds the thickness
of the workpiece, it will decrease and may become inadequate for
machining.

THE SECRET LIES IN THE POLE PITCH
       

THE MAGNETIC CHUCK
The chuck structure is a whole monoblock solid plate (dug from a
solid) while the magnetic and reeling parts are assembled under
the supervision of an advanced and automated process.
The resin treatment operation is done under vacuum to guarantee
an insulation and a longer magnetic life.

THE POWER UNIT
Includes a push-button panel for magnetizing and demagnetizing the magnetic chuck.
The mounting of the unit is made easy by the magnetic rubber applied on one side of
the external box.
It includes a 5 m supply cable without a plug to the supply and a 5 m earth cable
with a metallic cladding towards the magnetic chuck. The unit is preset for connecting
a safety signal (machine enabling device) which prevents the machine from running
when the chuck is not magnetized.

Magnetic chuck / BIMU2008

The right choice of one magnetic chuck rather than another is
represented by the ideal pole pitch for the machining at hand.
The pole pitch determines the ideal chuck for executing a range of
required machining operations. (See above Art. 88/89)
