The electrolyte system is respectively communicated with the drainage conducting device and the liquid outlet guide head. An anode of the power supply is connected with the workpiece to be machined and a cathode of the power supply is connected with the drainage conducting device. The device for electrochemically machining inner-step small deep holes has the advantages of being capable of achieving efficient machining of inner-step small deep holes and meeting dimensional accuracy requirements of products, high in machining efficiency, and low in machining cost. The device for electrochemically machining inner-step small deep holes can replace machine work, improve production efficiency by 7 times and lower energy consumption to be one fifth of machine work. Compared with machine work, the cutter consumption is reduced by 80% and production cost is reduced by four fifths.

Description

technical field [0001] The invention relates to an electrolytic machining device and method, in particular to a device for electrolytic machining of deep and small holes with inner steps. Background technique [0002] In the weapon system, especially in the weapon system of high-speed continuous-firing anti-aircraft guns, the processing of inner steps and small holes is very important. The size of the inner hole of the inner stepped deep hole is extremely small, the depth is extremely deep, and the aspect ratio is large, which brings great difficulty to the processing and manufacturing. Conventional processing methods are inefficient, difficult to ensure size, and high processing costs. Such as ordinary lathe processing, the tool bar is longer during turning, which is prone to vibration, low efficiency, high cost, and the size does not meet the requirements. The electrolytic machining process is adopted, with high production efficiency, low cost, and easy control of machin...
