Abstract
A method is designed to adjust automatically the dynamic balance of the main shaft of a processing machine. The method involves the use of a micro-electromechanical technique for a precision measurement of the imbalance quantity of the dynamic balance of the main shaft. The data are transmitted by the radio transmission technique to an automatic adjustment mechanism for adjusting the dynamic balance in conjunction with the phase difference of the rotary rings and a step-by-step motor.
