Abstract：In the drilling process of the deep hole, continuous strip-shaped chips are frequently produced to cause broken drill accidents, while if the chips are periodically broken during the drilling process, the problem of the chip removing in the deep hole machining process will be solved. A mechanical drilling device with low frequency axial vibration was designed. The working principle, the adjustment method of amplitude and frequency, and the whole structure layout of vibration drilling device were studied. The main technical parameters of vibration drilling device were analyzed and calculated. The dynamics simulation of rigid body was carried out by ANSYS Workbench, and the vibration characteristic tests of vibration drilling device were carried out. The results showed that the designed device had simple structure, the adjustment of amplitude and frequency was convenient, and the problems of chip breaking and chip removal could be solved to improve the processing quality of deep hole machining.
