The present invention concerns a method for producing riflings in barrels of guns including a barrel 6 as a workpiece 6 which defines an axis A in its longitudinal direction and which has a bore lying in the longitudinal direction which defines an inner wall of the barrel and a tool 8 comprising a tool head 10, which has an outer contour corresponding to the shape of the riflings to be produced, consisting of an electrically conductive material, wherein an electrolyte solution is pumped through the bore of the barrel 6, while the tool 8 is guided through the bore of the barrel 6, wherein a pulsed electrical voltage is applied to workpiece 6 and tool 8, with which a direct current is generated, the workpiece 6 being the anode and the tool head 10 being the cathode, the barrel 6 being positioned vertically with its longitudinal direction, wherein between the electrically conductive outer contour of the tool head 10 and the inner wall of the barrel 6 there is a gap surrounding the tool head 10, through which the electrolyte solution flows, and the tool 8 being moved relatively to the workpiece 6 through the bore of the barrel 6 during the application of the pulsed voltage and simultaneously rotated about the axis A, thereby producing the riflings on the inner wall of the bore, and means for carrying out the method.
A method for producing riflings in barrels of guns comprising a barrel as a workpiece, which defines an axis in its longitudinal direction and which has a bore extending in the longitudinal direction, which defines an inner wall of the barrel, and a tool, having a tool head which has an outer contour, consisting of an electrically conductive material, which corresponds to the shape of the riflings to be produced, wherein an electrolyte solution is passed through the bore of the barrel, while the tool is guided through the bore of the barrel,
An apparatus for producing riflings in barrels of guns, in which at least one barrel to be machined as a workpiece can be accommodated perpendicularly in the apparatus with its longitudinal direction, the apparatus having at least one upper and at least one lower receptacle, by means of which the at least one barrel can be held, wherein said apparatus comprises means for passing, preferably pumping, an electrolyte solution through said at least one barrel, wherein said apparatus comprises means for guiding a tool through said at least one barrel, wherein said tool can be guided through said barrel at the same time as said electrolyte solution is passed, preferably pumped, through said barrel,
