The electropermanent magnetic system
presents the best ratio performance / security / power consumption.
Indeed this kind of chuck needs power only to energise and
de energise the system (a few milliseconds).
Once energised, the chuck clamps the workpiece sufficiently
to machine in total security, without being affected by a
power failure. |
|
| |
|
| |
Particular attention has been devoted
to the perfect demagnetisation of the workpiece. This magnetic
system called " with total demagnetisation ", eliminates all
risk of residual magnetism. |

The permanent magnet (C) is not active.
The magnetic chuck is not active either. |

|
| The electric current passage during
a few milliseconds into the coil (D) turns on the clamping
system. |
| |
| An inverse electric current passage
turns off the system. |
