The invention provides a gas insulation protection jacking electrolytic machining cathode system and machining method. The cathode system is mainly composed of a jacking cathode, a cathode head and a ventilation module. In the jacking electrolytic machining method, an electrolyte laterally flows, and high pressure gas positively flows; and the machined profile of a workpiece gradually stretches into the jacking cathode, the high pressure gas with the pressure being adjustable in real time is blown into the upper end of the ventilation module, forms a uniform gas insulation layer on the surface of the machined profile of the workpiece, blows the stray electrolyte flowing into the cathode towards a gas horizontal channel and is blown out of a ventilation groove of the side of the cathode head. By adoption of the gas insulation protection jacking electrolytic machining cathode system and machining method, the electrolyte in the machined area can be conveniently reduced, the influence of stray corrosion on the workpiece profile is reduced, surface quality of a part is improved, and stability of a flow field in the machining area is improved.
