The Hydrokompenser system uses machine coolant, water, or other available fluids to perform balancing. A four-chamber balance container is integrated into the wheel carrier or flange of the rotating grinding wheel to allow for injection of the correction medium. To achieve balance, a compensation counterweight is produced by addition of fluid to the chambered container that offsets the imbalance of the wheel assembly.
Magnitude and location of the imbalance are determined by a special measurement technique, using the systems rpm sensor and vibration sensor as inputs. The control unit processes this information to monitor the balance condition of the machine, and to control the balancing operation. The balance correction fluid is supplied via four injection nozzles to the four respective correction chambers. The delivery of fluid required for proper balancing is controlled by solenoid valves.
