Automatic Integrated Balancing Solutions

Active balancing involves measuring vibration and correcting unbalance during rotation of a part. This means that balancing occurs without the need to interrupt operation! With Hofmann’s active balancing systems, the availability of machines and equipment is significantly increased, maintenance intervals are extended, and production failures and downtimes are largely avoided. Typical applications are:

Type: Active Balancer AB 9000

AB 9000 type active balancing systems are fast, precise, versatile and easy to upgrade.

Special features

• Fully automatic balancing of systems (e.g. fans, grinding, milling and turning spindles, centrifuges) in one or two planes during operation; no machine shutdown
• Real-time monitoring of unbalance vibrations
• Simple integration, including upgrades, due to ring design
• Balancing at high rotational speeds in very short time by fast electro-magnetic actuator and adaptive balancing procedures
• Non-contact, wear-free transmission of drive power for the actuator that positions the balancing rotors.
• Pre-balancing software for manual correction of basic unbalance
• Neutralizing of balancing rotors
• Display of remaining balancing capacity
• ProfiBus / ProfNet certified; see certificate
• Windows-based operating software; also available for common machine controls

Application

• Fully automatic balancing during machine operation
• Correction of operation-related unbalances
  
  

Type: HydroBalancer HB 6000

The HydroBalancer HB 6000 from Hofmann compensates for large unbalance amounts by using fluids. Ring containers are used as balancing units which are divided into four chambers.

Special features

• Balancing during rotation on one plane with unbalance monitoring
  
• Balancing with the aid of fluids, e.g. cooling lubricant of a grinding machine
  
• High precision balancing through extremely fine fluid metering
  
• Space-saving integration of the ring container in the machine spindle or rotor
  
• Pre-balancing software for manual correction of basic unbalance
  
• Easy retrofitting of existing machines

Application

• Automatic balancing, e.g. of grinding wheels and grinding spindles during machine operation

Type: MecBalancer MB 4002

The MecBalancer MB 4002 is intended for the automatic balancing of grinding wheels and grinding spindles during operation.

Special features

• Balancing during rotation in one plane with unbalance monitoring
  
• Balancing through electro-mechanical displacement of two balancing weights in the balancing head
  
• Balancing heads with various balancing capacities for flange mounting or spindle integration
  
• Non-contact, wear-free transmission of power for the actuator motors

Application

• Automatic balancing of grinding wheels and grinding spindles
  
• Balancing during operation without machine downtime

Type: AB 9100

The balancing system AB 9100 is designed for permanent installation in a machine (for example machine tool or fan). The rotors can be balanced under operating conditions - at any time and without special preparation.

Special features

• Real-time monitoring of unbalance vibration
  
• Windows-based operating software; also available for common machine control systems

Application

• Manual correction of operational unbalance
  
• Upgrade to AB 9000 (active ring balancing system) easily possible
