The invention relates to a micro-texture
radial vibration auxiliary electrolytic
machining method for the inner wall of a rotary body of a thin-wall part. The method is characterized in that a tool
cathode with a micro-boss texture on the surface and capable of doing
radial vibration is connected with a negative
electrode of the power supply, the tool
cathode is connected with an ultrasonic
current generator, a thin-wall rotary body workpiece is connected with a positive
electrode of the power supply, and the columnar
electrode on the tool
cathode is arranged in a
linear array mode; an
electrolyte enters a reaction area between the tool cathode and the workpiece through a liquid supply
pipe; a
machine tool spindle drives the tool cathode to horizontally move in the
peripheral direction according to a preset trajectory, a certain
machining gap is reserved between the workpiece and the columnar electrodes on the tool cathode, the
machine tool spindle drives the tool cathode to do autorotation motion, and the tool cathode connected with the ultrasonic
current generator is used for constructing an ultrasonic energy field; the
electrolyte flowing out at a high speed is sprayed onto theworkpiece to obtain the required
machining morphology. The invention further provides an micro-texture
radial vibration auxiliary electrolytic machining device for the inner wall of the rotary body ofthe thin-wall part. According to the method and the device, the centering property, the stability, the precision and the efficiency for machining the micro-texture of the inner wall of the rotary body are improved.
