Abstract

The invention discloses a high-precision deep hole machining tool with an inner wing type structure and a machining method, and belongs to the technical field of high-precision deep hole machining. According to a machined deep hole structure, a hole with the diameter of 24 mm is formed in a position with the depth of more than 300 meters, and a slot hole with the diameter of 45 mm is formed in a deep range with the depth of more than 300 meters. A suitable cutting parameter tool is selected in the tool and the machining method. The machining method comprises the steps that tool feeding and discharging modes are arc modes during finish machining, and helical milling layered machining is carried out. High-precision deep holes of the type structure can be machined, and the machining success rate of the high-precision deep holes can be improved.

Description

technical field [0001] The invention belongs to the technical field of high-precision deep hole processing, and relates to the selection and processing method of high-precision deep hole processing tools, in particular to a high-precision deep hole processing method in complex structures of inner wings. Background technique [0002] In a vertical inner wing structure of a certain model, there is a group of holes that require high feature accuracy, and the depth of the hole location is large. The diameter of the deepest hole is ф24H8, and the depth reaches 314+0.10mm. The coaxiality of the group of holes is ±0.015, which is an important feature of the part. The precision required in relation to the assembly of the vertical tail. [0003] The traditional method of machining deep holes is drilling and boring. This type of machining firstly depends on the rigidity of the boring bar and tool. Affected by gravity, the boring bar cannot be level with the spindle of the horizontal m...
