发明名称 METHOD FOR DETERMINATION OF TENSION DIFFERENCE VALUE OF CUTOFF DISC AT A NATURAL-VIBRATION FREQUENCY
摘要 The method for determination of tension difference of cutoff disc at a natural-vibration frequency includes determination of tension difference of cutoff disc in three directions of the natural-vibration frequency. The first measuring of the above mentioned frequency is implemented in free position of cutoff disc relatively to measuring device. Then, the cutoff disc is turned at 45 DEGREE around its own axis and measuring is repeated, obtaining the above mentioned frequency. Then, the cutting disc is turned around its own axes in the second time at the same direction and the tension difference value is determined.
