6 OPERATION
6.1
Chucking
■
Remove any burrs and uneven areas on the workpiece contact surface to ensure that the workpiece rests against
the plate as evenly as possible.
■
Wipe the pole plate of the magnet and the contact surface of the workpiece clean.
■
If the magnet is equipped with a connector, remove it from the parking station and plug it in.
Always ensure that there is no dirt or water.
■
Position the workpiece.
■
Press the button for switching on the magnet. A light will flash to indicate the magnetising pulse.
■
If necessary, align with reduced holding force (holding force coding switch at level 1 to 5).
■
Switch on the full holding force, set the holding force coding switch to the highest level.
■
Check for sufficient holding force, e.g. carefully try to release the workpiece from the magnet by hand.
■
Connect/close the shielding.
■
Machine the workpiece.
NOTE!
Please note that, for physics reasons, reproducible holding forces can only
be achieved on electro permanent magnets from the lowest towards the
highest holding force level. To carry out a defined force reduction, the de-
magnetising cycle has to be initiated with the corresponding button between
the individual steps.
6.2
Releasing
■
When using the magnet vertically, secure the workpiece against falling.
■
If the magnet is equipped with a connector, remove it from the parking station and plug it in.
Always ensure that there is no dirt or water.
■
Use the corresponding button to initiate the demagnetising cycle. A light will flash to indicate the demagnetising
pulses. Wait until the demagnetising has been completed (red signal light permanently on).
■
Remove the workpiece.
■
If the workpiece still adheres due to residual remanence (for tool steel), use light taps to release it from
the magnet.
■
If the magnet is equipped with a connector, remove it from the parking station and plug it in.
Always ensure that there is no dirt or water.
■
If the magnet has a connector, only unplug this once the demagnetising cycles has been completed and
the red signal light is permanently on. Risk from electric arc.
DANGER!
Risk of electric shock!
The magnetic holding force is switched on and off with current pulses.
Electromagnetic and electro permanent magnetic chucks use high magnet-
ising and demagnetising voltages. An electric shock can result in death or
serious injuries.
■
If the magnet has a connector, only unplug this once the demagnetising
cycles has been completed and the red signal light is permanently on.
Risk from electric arc.
