Abstract

The invention discloses a polycrystalline diamond drilling and reaming integrated cutter and a machining method. Carbon fiber composite materials are widely applied to the aerospace and are almost machined by adopting a hole machining method. The polycrystalline diamond drilling and reaming integrated cutter comprises a cutter substrate (1) which is sequentially provided with a drilling end (2), a reaming end (3) and a clamping end (4) to form a stepped straight flute structure, wherein the drilling end is welded with a group of polycrystalline diamond (PCD) drilling end composite blades (5), and the reaming end is welded with a group of PCD reaming end composite blades (6). The polycrystalline diamond drilling and reaming integrated cutter is used for drilling carbon fiber composite materials.

Description

Technical field:

[0001] The invention relates to a carbon fiber composite material high-precision hole integrated drilling and countersinking, in particular to a polycrystalline diamond drill-sinking integrated tool and a processing method. Background technique:

[0002] Carbon fiber composite materials are widely used in aerospace, and the processing of carbon fiber composite materials is mostly hole processing. There are two main processing methods for drilling and countersinking: 1. Drilling first, and then changing the tool for countersinking. The coaxiality of the processed holes is not high, which affects the working performance of carbon fiber composite materials. 2. Use a combined drilling and spot-sinking tool. This structure requires high manufacturing precision of the tool, and the coaxiality of the hole is severely limited by the installation accuracy. The processing efficiency of the above two methods is relatively low, and in aerospace applications, low precis...
