Abstract
The present application provides a processing method of a metal composite structure including a first metal layer and a second metal layer stacked on the first metal layer. The processing method includes the steps of defining a first through hole in the first metal layer, and drilling in the first through hole toward the second metal layer to form a traction hole in the second metal layer. Then, hot melt drilling is performed on a surface of the second metal layer away from the first metal layer toward the first through hole, thereby causing the second metal layer to crack under a traction force of the traction hole to form a second through hole, and a portion of the second metal layer to be melted and squeezed to form a bushing which adheres to at least a portion of a sidewall of the first through hole.
