KENNAMETAL/BalaDyne TABS Total Automatic Balancing System

Description of System System Operation A balancing ring system is installed on the toolholder along with a controller at the operator’s workstation. The stationary coil system in the tower is mounted on the machine bench.The balancing ring system, which rotates withthe tool holder, contains two counterweight rotors which are designed to correct the vibrations on the tool holder. The rotors are held in place by permanent magnets and move only if programmed to do so. The rotors can withstand extremely high speeds and high levels of vibration without shifting position. The position of the counterweight rotors is determined by the vibration of the tool holder. For example, if the counterweight rotors are positioned opposite one another, no correction is required. If they are positioned adjacent to one another, maximum correction is carried out. Different levels of vibration correction can be achieved by altering the position of the counterweight rotors. The stationary coil system in the tower sends electrical signals to the counterweight rotors, thereby generating a magnetic pulse, which alters the position of the rotors to achieve an optimum operating state. Vibration is corrected within fractions of a second, whilst the tool holder is rotating. The magnetic pulse is transmitted across an air gap, so there is no magnetic connection between the balancing ring system on the tool holder and the stationary coil system.
