Abstract: Aiming at solving the problem which was caused by the highspeed mechanical spindle vibration that could damage elements manufacturing precision and surface quality under the working condition, the development from offline dynamic balancing techniques to online dynamic balancing techniques and their balancing devices in recent years were reviewed and summarized. The dynamic balancing devices principles and their advantages and disadvantages were analyzed and classified. The highspeed spindle online dynamic balancing techniques and their devices development were discussed and prospected. The results indicate that the hybrid online dynamic balancing techniques and the current three most representative balancing devices which are respectively motor driving type, spray type and electromagnetic drive type will be widely accepted and spotted in the future. Dynamic balancing development on promoting balance efficiency, rapid response, precision, adaptability and durability should be emphasized. The application of dynamic balancing techniques and their highly performance balancing devices have a promising future.

Key words: offline dynamic balancing techniques; online dynamic balancing techniques; highspeed mechanical spindle; mechanical vibration; dynamic balancing devices
