Description

technical field [0001] The invention belongs to the field of microhole processing, and relates to a processing device for microholes in a workpiece inner cavity. Background technique [0002] With the development of science and technology and aviation technology, the complexity of the part structure is getting higher and higher, and the structure of the inner cavity is also becoming more and more complicated, especially the machining accuracy of the micro-holes and facets in the inner cavity is getting higher and higher, but the cavity The processing of internal micro-holes is still a difficult problem in processing, especially the processing of inclined holes in the inner cavity is difficult to achieve. [0003] Currently, the most widely used method for processing inner cavity holes is to place the inner cavity structure on a drilling machine, drill through the wall directly from the outside of the structure, and then fill the cavity on the outer box wall by welding. This...
