Description
In-situ balancing of grinding wheels,
machine tool spindles or fans
normally is performed using portable
Hofmann field balancing
instrumentation. Therefore first the
vibration and speed sensors have to
be attached to the balancing object.
Then they will be hooked up to the
balancing instrument. Prior to
balancing one should check whether
unbalance really is the source of
vibrations. If yes, a calibration is
being performed until the instrument
presents to unbalance to be
corrected. After completion of
balancing the measuring equipment
will be dismounted again.
In case a balancing system AB 9100
is being used, that effort reduces to
just the unbalance correction.
Because that system will be
integrated into the machine.

It continuously monitors the
vibrations. And it indicates to the
machine control an event as soon as
the vibration exceeds a preset limit.
A necessary unbalance correction
may then be done very quickly,
because the calibration is available
already since the commissioning of
the system. As a result the
unbalance correction is now directly
shown.
A PC software is being used to setup
and operate the AB 9100 and to
guide the operator through the
balancing process. It may be
installed on an external PC or laptop.
It also may be installed on the PC of
a machine's PLC.
