Toolholder Balancer Brochure

Vertical Balancing MachineProfi Tool Balancer PTB 31.2Advantages ? Simple, reliable and intuitive operation ? Permanent calibration - independent from rotor weight and balancing speed ? Direct conversion of unbalance into all practical correction units ? Precise transfer of correction position onto workpiece by line laser ? High measuring accuracy and precise clamping devices for achieving smallest residual unbalances ? Sidewards opening safety shroud for long operation without fatigue ? Practical storage place for adapters and accessories Applications Description ???Balancing of ? toolholders ? tools ? other rotors without own journals (for example blower or grinding wheels) Checking unbalance of work-pieces in goods receiving department Balancing in tool maintenance ???The workpieces are being clamped manually or automatically with highest precision using the suitable adapters. The unbalance is evaluated using piezo force sensors and digital signal processing. For the unbalance correction, the workpiece is being automatically indexed into the corresponding angular position. Alternatively, this is performed by the operator by means of the electronic pro-tractor. ? The polar unbalance is being converted by the unbalance measuring system into practical correction units (components, compensation rings, drilling, milling).
