HSC spindle with AB 9000 balancing unit

Description

Principles of operation

The active balancing system

AB 9000 automatically compensates

unbalance during the operation of a

machine. Therefore two balancing

rotors are built into the rotating part

of the balancing unit. These rotors

rotate freely on the rotational axis.

If the rotors' balancing weights are

positioned directly opposing each

other, their effect is neutralised. The

full balancing capacity is obtained by

placing the weights at the same

angular position. By moving the

weights to a specific angle, any

unbalance correction with respect to

magnitude and angle can be

obtained within the mentioned limits.
