The purpose of this paper is to investigate the precise screw tightening by means of harmonic vibration. In this report, the findings of the investigation on the vibration tightening in which the torsional vibration is superposed upon the motorwrench tightening with a D, C, servo-motor are given. The main results are as follows : (1) The torque coefficient is decreased by means of the reduced equivalent coefficient of kinetic friction by vibration during vibration tightening. (2) The reduction of scattering of the torque coefficient as the results of the vibration tightening under lubrication in addition to the lubricant effect of various oils is clear and the amount of scattering becomes stable. (3) The torque coefficient is reduced remarkably under resonance condition in vibration tightening. By this study, it is proved that this vibration screw tightening has the possibility of effective tightening.
