SBS has taken balancing grinding machines to a new level of accuracy, speed, and convenience.

With the new electroluminescent display, the SB-4475 model balancer puts more control and information at your fingertips. Quicker setups and dynamic graphic displays keep you well informed and in total control. The system is elegantly simple; a computer control, sensor, spindle mounting- adapter, and balance head.

The balancer takes the magic out of wheel balancing. Fully automatic operation means you no longer need to pre-balance grinding wheels, and eliminates the need for awkward equipment, which only does part of the job.

The SBS Dynamic Balance System operates on a principle of mass compensation for wheel imbalance. The balance head contains two movable eccentric weights. Each weight is driven by electric motors through a precision gear train. These weights can be repositioned to offset any imbalance in a grinding wheel.

The sensor picks up imbalance or vibration. The signal is fed to the controller, which filters the signal by RPM. The controller then drives the two balance head weights in the direction that reduces the amplitude of the vibration signal. When the weights are positioned so the lowest vibration level is reached, the balance cycle is complete.
