The invention discloses a right-angle side golden finger milling machining method and a machining method adopting a multi-edge milling cutter, and belongs to the technical field of golden finger machining, and the method comprises the following steps that the edge of a golden finger is repaired through a controlled deep machining method, and the cutter path of the controlled deep machining method passes through the connecting part of the golden finger and a lead along the edge of the golden finger; the removal amount of the cutter is controlled to be 5-50 [mu] m/r, and the machining depth is set to be H1-H1 + 10 [mu] m, so that the lead is cut off or removed to obtain a golden finger structure with a smooth cutting surface; and replacing the end mill, and milling the base material layer in the processing area to obtain the golden finger plate with the cutting surface perpendicular to the plate surface. According to the milling machining method for the right-angle edge golden finger, the probability that burrs
