Device for preparing flexible cathode for electrolytic machining

The utility model discloses a device for preparing a flexible cathode for electrolytic machining. The device comprises a box body, a spray gun, a laser, a laser conduction device and a microwave source, a workbench used for bearing a machined workpiece is arranged in the box body. A through hole for a laser beam to pass through is formed in the upper side surface of the box body above the workbench; the microwave source is communicated with the box body so as to provide microwave energy for the box body; a nozzle of the spray gun can be aligned with the workbench; the laser conduction device comprises an X-axis galvanometer, a Y-axis galvanometer and a plane lens. Laser beams emitted by the laser device can be focused on the workbench after sequentially passing through the X-axis galvanometer, the Y-axis galvanometer and the plane lens, movement of the laser beams in the X-axis direction and the Y-axis direction is controlled by controlling deflection of the X-axis galvanometer and theY-axis galvanometer, and
