Abstract:Rotating ultrasonic drillinggenerate low noise in building but is also low in efficiency. In light of this phenomenon, the mechanism of vibration drilling is improved and verified by experiments. First, a prototype guaranteed normal operation is installed for ultrasonic and low-frequency rotatingvibrationdrilling . Then the drilling efficiency is tested on clay bricks and the vibration is analysed. The results show that low frequency vibration doubles the drilling speed andmaintains the pressing force between the drill bit and processed surface while the interaction time decreased by about 80%.Besides, the noise iscapped below 60dB (A) during the process. To speed up drilling, ultrasonic vibration crushes brittle brick into particles, and low frequency vibration hastens the particles out of the cutting area. In short, the comprehensive drilling techniquetakes advantages of ultrasonic and low frequency vibration to increase the efficiency, and is promising in equipment development.
