 Such as figure 2 As shown, multiple tool cathodes 6 are distributed on the same horizontal plane P0, and multiple tool cathodes 6 are spaced at an angle Among them, N and M are natural numbers greater than 1, and M is the number of blades of the overall impeller; the ends of a plurality of tool cathodes 6 close to the center of the impeller blank 7 are distributed on the same circle C, and the diameter of the circle C is D=D 0 -2L+2δ, where D 0 is the diameter of the integral impeller 7, L is the length of the integral impeller blade, and δ is the electrolytic machining gap at the end of the cathode; the impeller blank 7 is placed horizontally on the horizontal plane P 0 Below, the impeller blank 7 axis L 0 The extension of the line passes through the center of the circle C.
 Such as image 3 As shown, when ready for processing, the tool cathode 6 is located above the overall impeller blank (position 9 in the figure). n Rotate (parallel to the central axi...
