Tubular electrode for electrolytic machining of deep and narrow groove structure and electrolytic milling method

The invention provides a tube electrode for electrolytic machining of a deep and narrow groove structure and an electrolytic milling method, and belongs to the technical field of electrolytic milling of tube electrodes. Comprising a horizontal end face and an inclined end face, the horizontal end face is a semicircular face, and the inclined end face inclines from the end face of the semicircular face to the side wall of the tube electrode body. A pulsating electric field is formed through arrangement of the insulating layer, a pulsating flow field is formed through arrangement of the inclined end face, the pulsating flow field can strengthen the flushing effect in the machining gap, the pulsating electric field can disperse the material dissolving process and product distribution, the discharging efficiency of electrolytic products in the machining gap can be greatly improved through coupling of the pulsating flow field and the pulsating flow field, and the influence on the machining process is reduced.
