Hofmann GmbH & Co. KG – AB 9000 ring balancing system
■
Overview
AB 9000 ring balancing system
The AB 9000 ring balancing system is based on a brilliantly simple
concept. The vibrations generated on rotating systems due to im-
balance are actively and quickly eliminated as the system rotates.
Two balancing rotors are permanently mounted on the tool spindle
via thin ring bearings. A fast, intelligent controller uses sensors to
detect the imbalance in the spindle, calculates and adjusts the
position of the two balancing rotors electromagnetically until they
are ideally positioned to compensate the imbalance.

Benefits
7
Automatic (active) balancing of all kinds of rotors
7
Balancing during operation without machine shutdown
7
Implementation of test imbalance for the purpose of
system identification
7
Generation of unbalance for acceptance tests
■
Function
•
Automatic (active) balancing of rotors (e.g. grinding wheels,
grinding spindles, turning chucks, fans) in one or two planes
with imbalance monitoring
•
Active balancing during operation without machine shutdown
•
Ring-shaped balancing unit for efficient, space-saving
integration into the rotor
•
Very fast balancing even at high rotational speeds by electro-
magnetic actuator and adaptive balancing process
•
Non-contact, wear-free transmission of actuator energy
between stator and balancing ring
•
Pre-balancing software for manual correction of basic
unbalance - AB 9000 then only balances the new operational
unbalances.
•
Balancing unit can be neutralized, e.g. for pre-balancing.
•
Indication of remaining balancing capacity
•
PC operating software
■
Integration
The AB 9000 can be used for the following CNCs:
•
SINUMERIK 828D
with separate PC
•
SINUMERIK 840D sl:
- with SINUMERIK PCU 50.5 Windows 7
- with separate PC
