2 SAFETY
NOTE!
All persons working in operation, maintenance and servicing of the preci-
sion sine tables on machine tools etc. must be appropriately qualified and
observe the operating instructions in all details.
The operating instructions comprise all information required for safe and
optimum use of the magnetic chucks. This concerns not only the functional
reliability of the precision sine tables, but also your personal safety.
Do not remove any warning symbols and instructions from the magnetic
chuck!
Danger – strong magnetic field!
The exposure zone of the magnetic field poses a risk of injury and death
for persons with pacemakers, electronic medical device implants, active
implants or ferromagnetic foreign bodies.
Minimum distance 2 m!
■
Whether persons with pacemakers, active implants or ferromagnetic
■
foreign bodies can work on machines with magnetic chucks has to be
decided in each individual case and upon consultation with a physician.
Measurements may have to be carried out.
In any case, the hazard zone has to be limited in such a way that the
■
basic limit of 0.5 mT is not reached.
The applicable limits in the exposure zone of the magnetic field as per
■
BGV B11 (Regulation issued by the German Social Accident Insurance
Institutions), Annex 2, are not exceeded.
- Peak values for head or torso: 2.000 T
- Mean value for 8 h full-body exposure: 0.212 T
- Peak value for extremities: 5.000 T
- As the magnetic saturation for steel 1.0037 is 1.6 – 1.9 T and the
magnetic field is concentrated in the area near the pole plate, the
limits stated above are not exceeded in the range > 10 cm.
- As per the Bavarian Environment Agency (LfU) and the German Federal
Occupational Health and Safety Regulation (EMFV) of 15/11/2016,
constant magnetic fields < 2 T have no adverse effect on health.
Risk of crushing!
There is risk of crushing when placing ferromagnetic parts on the active
magnet.
Always position workpieces while the chuck is not magnetised.
■
The use of non-magnetic tools can exclude the risk of crushing or similar
■
injuries.
