Micro-electrical discharge machining technology and device for surface array group budge of cylindrical rod piece

The invention relates to a micro-electrical discharge machining technology and device for a surface array group budge of a cylindrical rod piece, belonging to the field of a micro-electrical discharge machining technology. The micro-electrical discharge machining technology and device for processing the surface array group bulge of the cylindrical rod piece are characterized in that a spindle is provided with a chuck clamping workpiece; a central apex is fixed on a slider and connected with the workpiece; the spindle is connected with a special chuck to drive the workpiece to rotate at a constant speed; a radial processing electrode is mounted on the spindle of a machine tool; along with the constant-speed rotation of the workpiece, the radial processing electrode feeds along a Z-direction servo and moves along an X direction at the same time to finish the processing; and when an axial processing electrode is mounted on the spindle of the machine tool for processing, the workpiece is fixed, and the axial proc
