【Abstract】 Deep and small holes drilling in Titanium alloy is one of the difficulty problem in metal cutting. A good result has been obtained for solving tiaese problems by applying low frequency axial vibrating drilling with gundrill. In this paper, the gundrill design, chip breaking and cuttin,g quality are studied. The results of experiment show that with reasonably parameters, this new technique will improve the cutting precission by 1-2 grade and surface finish by 2-3 grade. Besides, the productivity will also be considerably increased and chip be reliably broken.更多还原
