Based on the principle of vibration drilling, the mathematical model of average friction force during vibration drilling was established, and the influence law of dynamic load on average friction was analyzed. Ordinary drilling and ultrasonic vibration drilling tests were carried out on the 0Cr17Ni4Cu4Nb stainless steel on the ultrasonic vibration drilling test device. The surface roughness of the hole wall, bit wear morphology and cutting shape were compared and analyzed. The test shows that ultrasonic vibration drilling can reduce the average friction force; by observing the surface morphology of the drill bit and the hole after processing, the ultrasonic vibration drilling bit has low wear degree, the surface roughness value of the hole wall is small, and has better chip breaking and row discharge.
