They can be used for balancing grinding wheels, fan blades, rotating cutting tools, pulleys, sheaves, and many other parts. Frames are cast iron and accurately machined to hold steel discs which are hardened and ground. The discs revolve freely on steel balls running in hardened and ground races. Chilled iron discs are used in larger units designed to carry heavy loads. STATIC BALANCING Imbalance is the uneven distribution of weight. Static Balancing is a weighting process to detect the imbalance of a circular or cylindrical part which is free to turn on an axis. A part to be balanced is placed on the four discs of the Balancing Tool. An unbalanced part will rotate until the heavyside is downward. Balance is accomplished by adding a counter-weight to the lighter side, or by removing weight from the heavy side. When the part remains motionless when placed in any position in 360°, it is then in static balance. ADJ. BLOCK MADE IN USA
