Abstract: The invention relates to the technical field of electrochemical machining and provides a pulse dynamic electrochemical machining apparatus and method for rapidly leveling a surface of a revolving part. During rotating pulse dynamic electrochemical machining, a cathode tool rotates around a center point of the cathode tool at a constant angular velocity, and an anode workpiece rotates around a center point of the anode workpiece at the constant angular velocity; meanwhile, the cathode tool performs a feed movement at a set feed velocity along a center line of the cathode tool and the anode workpiece. A control system determines a machining voltage value output by a power source when each contour point of the anode workpiece rotates to a machining area to automatically change an applied voltage between the cathode tool and the anode workpiece.
