Abstract

The invention discloses an ultrasonic-frequency vibrating combined micro-electrical discharge and electrolysis machining device and belongs to the technical field of combined precise and micro special machining. According to the ultrasonic-frequency vibrating combined micro-electrical discharge and electrolysis machining device, ultrasonic-frequency vibration at a certain frequency is applied to a tool electrode and a workpiece, so that the workpiece machining efficiency is effectively improved; an ultrasonic vibration device is structurally symmetrical, and thus the workpiece machining stability is improved; the workpiece is assisted with ultrasonic vibration through the ultrasonic vibration device, and thus transverse electrical machining and longitudinal electrical machining are facilitated. According to a feeding mechanism of the machining device, a servo motor is preferably used for driving a workbench mechanism to finely move on a ball screw guide rail for feeding, fine feeding can be achieved through the feeding mechanism, and thus machining of a complicated curve surface of the workpiece can be achieved. The ultrasonic-frequency vibrating combined micro-electrical discharge and electrolysis machining device is novel in structure, and the electrical machining efficiency and precision are effectively improved; the defects that during ultrasonic combined electric machining of a workpiece with a large depth-diameter ratio, the efficiency is low, and it is quite difficult to machine a complicated special-shaped surface are overcome.
