Problems solved by technology

Among them, although the laser can be used to process small diameter holes, if laser processing is used, the processed hole will be a small hole like a trumpet mouth. Therefore, it is mainly used for processing trumpet holes with low precision requirements. small holes, but cannot be used to process straight holes with high precision requirements; for straight holes with high precision requirements, EDM is a good choice, and it can process small holes with a minimum diameter of 0.08mm, but EDM During the processing, due to the action of electricity and heat, the recast layer will be left on the hole wall of the small hole, which will deteriorate the surface quality of the hole wall of the small hole, thus affecting the service life of the small hole

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a processing technology for dense small holes. Background technique [0002] For the processing of intensive small holes, laser and electric spark processing methods are mainly used at present. Among them, although the laser can be used to process small diameter holes, if laser processing is used, the processed hole will be a small hole like a trumpet mouth. Therefore, it is mainly used for processing trumpet holes with low precision requirements. small holes, but cannot be used to process straight holes with high precision requirements; for straight holes with high precision requirements, EDM is a good choice, and it can process small holes with a minimum diameter of 0.08mm, but EDM Due to the action of electricity and heat during processing, the recast layer will be left on the hole wall of the small hole, which will deteriorate the surface quality of the hole...
