It is difficult to process high-temperature alloy and obtain high surface quality in ordinary drilling Ultrasonic vibration drilling can improve the machining quality of hole surface quality. Firstly, the principle of ultrasonic vibration drilling will be introduced , the device is designed and the 3D horn modeling is built. The horn by ultrasonic vibration drilling analysis, generating modal formation frequency and obtain the optimal frequency. Finally, the high-temperature alloy material by ultrasonic vibration drilling is carried out with the optimum frequency. The results show that the surface roughness of the hole can be reduced by ultrasonic vibration drilling and the surface quality can be better compared with ordinary drilling.
