Composite synchronous supersonic vibration fine electrolytic machining apparatus

The utility model discloses a compound synchronous ultrasonic frequency vibration fine-electrolysis processing device, the micro-pressure contact between a work piece and a micro-fine cathode is kept through a micro-pressure adjusting device, and the dynamic quick measuring to the ultrasonic vibrating position of the micro-fine cathode is carried out by a laser micro-displacement sensor, which is converted into electrical signals which comprise the ultrasonic vibrating frequency, the phase position and the amplitude value and then is transmitted to a chopped wave circuit for processing and converting, chopped wave signals which generates the make and break electrolysis power supplies realizes the accurate common-frequency and synchronization between the electrolysis power-on and the cathode ultrasonic frequency vibration, the electrolysis current is converted into voltage signals by a current sensor, which are displayed, measured and memorized by a numeral memory oscillograph, and are transmitted to a control
