This applies to some small flywheel, fan, fan, feed pump impellers, blades, etc. There is now more widely used one of balancing machines. High precision, high efficiency, easy operation, intuitive display, good stability, man-machine dialogue is their major characteristics. The aircraft just before the start, after a simple calibration procedure operation, you can start running after the first, accurately and quickly shows the workpiece unbalance magnitude and phase, especially for balanced detection bulk of the workpiece.
