The active face (pole face) of a magnetic chuck is composed of a succession of steel poles with high magnetic permeability (A). They are enclosed with non-magnetic material (B).
Machining of small work pieces TURBOMILL 18
Machining of medium and large work pieces TURBOMILL 25 & 40
The permanent magnet (C) is not active.
The magnetic chuck is not active either.
The permanent magnets (E) and (G) are always active. The magnetic circuit is shunted and the pole face is not active.
The electric curent passage during a few milliseconds into the coil (D) turns on the clamping system.
An inverse electric current passage turns off the system.
The electric current passage during a few milliseconds into the coil (F) permits to reverse the polarity of magnets (G).
The magnetic field generated by magnets (G) and (E) are oriented to the polar face of the chuck, which becomes active and clamps the work piece to the machine.
A new electric current passage turns
off the system.
the "plus" of
walker braillon magnetics
The Walker Braillon Magnetic systems differ from other electropermanent concepts in that it favors maximal flux concentration.
