Problems solved by technology

[0004] However, due to the limitation of abrasive flow velocity and other factors, the energy carried by abrasive flow processing is limited, resulting in relatively low processing efficiency, and it is difficult to achieve fast and efficient processing. In order to improve the processing efficiency of abrasive flow, scholars at home and abroad have gradually begun to Ultrasonic assisted abrasive flow processing, due to the high vibration frequency of ultrasonic waves, can instantly give high energy to abrasive flow and improve the processing efficiency of abrasive flow. Now more and more ultrasonic assisted abrasive flow However, the current ultrasonic-assisted abrasive flow processing is only to install ultrasonic transducers in the forward or reverse direction of the abrasive flow. Although this method improves the processing efficiency, the direction of the ultrasonic energy cannot be effectively controlled. , only by controlling the vibration energy of the ultrasonic wave, it is easy to cause the processing surface quality to be affected in the case of improving the processing efficiency, and in the case of high processing surface quality, the processing efficiency is low. Therefore, how to use force and reaction force The principle of decomposition, to provide a method that can change the direction of the ultrasonic transducer to the abrasive particle flow, to change the polishing efficiency by adjusting the impact direction of the abrasive particle flow on the workpiece under high vibration frequency, and to improve the quality of the polished surface, is what people hope to solve technical problem
