Main technical schemes of the present invention: tool construction is, on a conducting metal body close with length of tube, have and the corresponding helicla flute of barrel rifling, in helicla flute, stud with and the corresponding screw type insulator of groove panel, and be adhesively fixed with epoxide-resin glue, this body and function of conducting metal copper product is produced, screw type insulator panel is produced with pmma material, wherein be used for the technological process of Electrolyzed Processing barrel rifling: A, assembling, on the electrolysis lathe, barrel rifling instrument E is installed in its corresponding barrel F in the mode of excessive cooperation, then tightens up and be connected with sealed support 13; B, electrolysis rifling, opening power is regulated DC voltage 10～15V, DC current 1000～3000A, opens the electrolyte that pressure is 2Mpa, and electrolysis 1～2 minute gets final product the spiral rifling that electrolysis goes out barrel; C, check are to the barrel diameter tolerance
+0.03mm, roughness Ra0.1mm tests.
The present invention proves by part gun and the processing of deep hole part spiral fluted: compare with the processing of swap cathode method, as long as the working (machining) efficiency that can improve rifling is processed one 1-2 minute more than 4 times; Reach diameter tolerance fully
+0.03mm, the specification requirement of roughness Ra0.1mm; Can process the gun barrel that bore is 7.62-40mm, many spiral riflings of transmitting tube.This instrument can be used for the processing of the civilian part of deep hole helicla flute of similar barrel equally.
