Problems solved by technology

[0004] The purpose of the complex surface finishing equipment and process of the present invention is to disclose a direct excitation of the ultrasonic horn in order to solve the difficult problems and existing serious deficiencies in the above-mentioned existing complex parts inner surface finishing process. The high-intensity ultrasonic vibration generated by the workpiece interacts with the liquid-solid two-phase fluid that is forced to flow on the surface of the complex workpiece, resulting in the impact between the workpiece surface and the abrasive particles and the cavitation of the liquid, resulting in the impact of the abrasive particles on the surface of the workpiece. Finishing, especially the concave surface of the complex channel also has high-intensity ultrasonic vibration and the pervasive characteristics of liquid-solid two-phase fluid, which ensures that the concave surface and inner dead angle also have a good finishing effect.
