The processing damages such as delamination and tearing were easily produced during the drilling of the sleeve holes of GFRP, which were directly related to the axial drilling force. In order to improve the quality of GFRP hole-making, a new diamond thin-wall trepanning tool was adopted; and combined with the low-frequency axial vibration machining technology, the kinematic model and the dynamic model of single abrasive particle were established. The variation law of axial force in GFRP hole-making was experimentally studied. The burning probability and the automatic blanking rate of trepanning tool were analyzed. The results show that the instantaneous feed rate and the axial force of low-frequency vibration drilling are larger than that of conventional drilling. Besides, the axial force increases with the increase of amplitude, and the axial forces of the low-frequency vibration drilling and the conventional drilling increase with the increase of feed speed and decrease with the increase of spindle speed. At the same time, the abrasive particles participate in drilling intermittently, which greatly reduces the burning probability of the trepanning drill and improves its automatic blanking rate. The automatic blanking rate during low-frequency vibration drilling is up to 88.24%, which can realize the continuous batch hole-making of GFRP.
