Available on all Cincinnati Series Centerless Grinding Machines, but can be applied to any dual or "twin grip" machine.

The SBS Dynamic Balance System can accurately monitor and routinely balance the grinding wheel/spindle assembly below 0.000008" (0.2 micron peak to peak displacement), vibration amplitude during machine operation.

• Designed and built of the highest quality materials to survive in the grinding environment.
  
• Wheel balance is maintained even after shutdown. Compensation is sufficient that no pre-balancing is necessary with new wheels.

• Use of calibrated vibration sensor eliminates the need for any calibration or setup. The sensor used is common in the industry, and will correlate to readings taken from plant vibration analysis equipment.
  
• Effective in balancing both single speed and constant surface footage (variable speed) applications.
  
• Mounted atop the operator station, the controller display shows spindle RPM and vibration amplitude. Vibration amplitude can be viewed either in inch or metric, and in displacement or velocity.

• Balancer weight assembly mounted in convenient location. Since the weight assembly can be moved from spindle to spindle in seconds, the expense and redundancy of duplicate units is avoided on Twin Grip machines.
  
• All Twin Grip machines use an electrical connection in the front of the machine. A quick ¼ turn military type connector is used for convenience, with special polyurethane sheathed cable for durability.

When the balancer control measures a vibration amplitude that exceeds the programmed high tolerance, a red indicator light on the control panel is lit, and a signal is sent to the CNC interface. If this occurs during a dwell prior to a dress cycle, the automatic balance cycle can be initiated either manually or automatically via the machine control, and runs until the wheel is balanced to the programmed limit.

High and low vibration amplitude limits and the balance cycle time limit are programmed into the SBS controller. The high tolerance setting determines when balancing is required. The low limit is the target value which represents an acceptable balancing result. Initial values are determined, and set at the factory. These values can be easily changed in the field to suit the job requirements.
