Description

technical field [0001] The invention relates to an ultrasonic elliptical vibration processing device, in particular to a dual-excitation ultrasonic elliptical vibration processing device, which belongs to the technical field of mechanical processing. Background technique [0002] Vibration-assisted machining is a new type of machining technology that appeared in the 1950s. It can effectively improve the machining quality, so it has received widespread attention. Early vibration-assisted machining technologies were mostly low-frequency one-dimensional vibration-assisted machining, that is, vibration in the cutting direction. In the 1990s, Japanese scholars proposed the elliptical vibration technology for the first time, in the form of flexural vibration of the horn through the stretching vibration of two sets of vertically distributed piezoelectric ceramic sheets, and synthesized elliptical vibration trajectories at both ends. Compared with conventional cutting, elliptical v...
