Problems solved by technology
[0004] The common method of ultrasonic EDM composite machining is to add a certain frequency of ultrasonic vibration to the tool electrode, and use the suction effect of the tool electrode to improve the EDM processing conditions. However, because the electrode is very small, its rigidity is small, and it will Lateral vibration, it is difficult to guarantee the radial machining accuracy of micro holes
In addition, when a transducer that generates ultrasonic vibrations is added to the tool electrode, it is necessary to make major changes to the electrode structure and its control system, thus making the structure more complex

Description
technical field [0001] The invention relates to the technical field of ultrasonic electric discharge composite machining, in particular to an ultrasonic electric discharge composite machining vibrator based on a longitudinal-torsion composite mode. Background technique [0002] In EDM micro-hole machining, due to the small size of the micro-hole and the narrow discharge gap on the end surface, the electro-corrosion products tend to accumulate at the bottom of the hole, making it difficult to remove chips and soon fill the entire gap. The stable discharge gap range is small and easily affected. Influenced by other process parameters, it is easy to cause frequent short circuits and abnormal discharges; in order to achieve micron-level machining dimensional accuracy and surface accuracy, the discharge energy of each pulse must be reduced, and the erosion amount of the processing is very small, which affects the processing speed; EDM micro-hole machining can not flush the proces...
