Summary:The invention discloses a processing technology of an intensive type tinier hole. The processing technology comprises the following steps of: (1), positioning: positioning to-be-processed working parts on which the intensive type tinier holes need to be processed on an operation platform by adopting a tool clamping apparatus; (2) pre-drilling: carrying out pre-drilling on the to-be-processed working parts by adopting a first solid borer to form the intensive type tinier roughcast holes; (3) molding drilling: repairing a position degree and pore size on the intensive type tinier roughcast holes by adopting a second solid borer so as to achieving the design size; and (4) finishing a fixture: removing a borehole trace on the tool fixture. Through the manner, the processing technology provided by the invention has the advantages that the position degree and precision of the hole are improved, meanwhile, the surface quality of the hole wall is improved, and the service life is prolonged.
