Abstract

The invention relates to a processing method for titanium alloy inclined plane step holes. The processing method is characterized in that a special composite processing cutter is used, the composite processing cutter is of a coaxial, sectional, unified and integral structure, and the three sections of structures, namely a drill head part (1), a cornish bit part (2) and a screw cap (3) are arranged in series according to the distance with a cutter handle (4) from far and near sequence; and the specific requirement of the processing method for the titanium alloy inclined plane step holes is as follows: (1) the screw cap of a composite expanding drill is adjusted, (2) a test piece is tested, and (3) the test piece is measured to qualify so as to carry out part processing. The processing method provided by the invention breaks through the technic bottle neck of inclined plane step holes process, guarantees the smooth implementation of development production of a compressor wheel disc, and provides precious referential experience for the later similar part process.

Description

technical field [0001] The invention relates to a processing tool and processing of a titanium alloy inclined-plane stepped hole, and in particular provides a processing method for a titanium alloy inclined-plane stepped hole. Background technique [0002] In mechanical engineering technology, especially in the processing and manufacturing of titanium alloy fan shaft parts, closed deep cavity thread processing is a major technical difficulty. This kind of technology has never been used before, and it is the first contact. There is no similar processing for reference. craft. The titanium alloy fan shaft is the key part. The structure of this part is complex. The thread processing space of the closed deep cavity is narrow. big. The material is titanium alloy, which is a difficult-to-machine material, and the thread processing of the inner closed deep cavity cannot be realized according to the traditional process. Closed deep cavity thread processing technology must ensure t...
