Abstract

The invention discloses a drilling tool and a drilling method.The drilling tool for the weakly-rigid component comprises a tool body, a rough machining blade, a finish machining blade and an annular transition groove surrounding the tool body by a circle, and the tool body is provided with an annular groove in the direction from the cutting end of the tool body to the mounting end of the tool body; the diameter of the rough machining blade is smaller than that of the finish machining blade, and the width of the annular transition groove is larger than the thickness of a component. A hole making method for a weak rigidity component comprises the machining steps that a primary hole is drilled in the component; and forming a final hole in the component by adopting a hole forming tool. According to the hole making cutter and the hole making method, the technical problems of large deformation and low hole making precision in the hole making process caused by a traditional machining cutter and a traditional machining method are solved. Deformation in the drilling process is reduced, so that hole position deviation, hole diameter deviation and roundness deviation are improved, and drilling precision is improved.

Description

technical field [0001] The present application relates to the field of boring, and in particular, to a hole-making tool and a hole-making method for weakly rigid components. Background technique [0002] With the development of material preparation technology and equipment technology, laminated materials of weak rigid components are more and more widely used in the aviation field, and at the same time, the processing requirements are getting higher and higher, and the processing difficulty is becoming more and more difficult. For example, the height of the edge strip is 50mm~100mm, the wall thickness is 1.5mm~3mm, the hole position accuracy is Ø0.05mm, and the hole diameter accuracy is 0.03mm-0.05mm. [0003] For high-precision hole processing of laminated materials of weakly rigid components, at present, the traditional processing method is to directly use a drill for final hole drilling. Traditional machining tools and machining methods will cause the hole to become an el...
