Problems solved by technology

This is because aramid fiber has good flexibility, and its composite material is not easy to be cut when drilling and milling. The traditional method of directly drilling the processing surface will cause uncut fibers and resin to accumulate at the fracture, resulting in rough processing surface. , fuzzing, even delamination, burnt

Embodiment Construction

[0030] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0031] In the present invention, in the case of no contrary description, the orientation words "inner and outer" used are defined based on the inside and outside of the cutter body contour, and the "axial, radial, radial, "Circumferential" is relative to the rotation axis of the tool body. Specifically, the tool body rotates around the axis, and the extension direction along the axis is "axial", and the direction perpendicular to the axis is "radial". The direction of the axis is "circumferential".

[0032] First of all, it should be noted that, in the preferred embodiment of the present invention, although the overall structure of the tool body 2 of the compou...

Abstract

The invention discloses a drilling-milling compound tool and a drilling and milling method of fibrous composite. The drilling-milling compound tool comprises a tool body having a bit end surface, a plurality of chip grooves and a cutting portion divided by the chip grooves are arranged on the tool body, the cutting portion comprises a first cutting edge and a second cutting edge formed on the bit end surface, the bit end surface forms a concave structure and is provided with a drill point protruding outwardly along the axial direction in the center of rotation, and the drill point is parallel with an edge cutter point of the second cutting edge or protrudes slightly the edge cutter point of the second cutting edge. When drilling-milling operation is started, the drill point can locate and cut rapidly materials to be processed, such as fiber, via the edge cutter point of the second cutting edge, and drilling operation on cut fiber materials can be completed; further, milling operation of milled grooves and milled holes can be completed via the first cutting edge, so that one tool can be used to finish drilling and milling compound process of board typed parts such as aramid fiber composite.

Description

technical field [0001] The present invention relates to the field of drilling and milling tools, in particular, to a drilling and milling composite tool and a method for drilling and milling fiber composite materials using the drilling and milling composite tool, and more specifically, to a method for applying the drilling and milling composite tool to aramid Drilling and milling field of fiber composite materials. Background technique [0002] Fiber composite materials are widely used. For example, aramid fiber reinforced composite materials have low compressive strength, high toughness and good impact resistance. Aramid fiber is a high-tech synthetic fiber with high strength, medium modulus, light weight, It has the characteristics of high temperature resistance, insulation, anti-aging and long life cycle. However, in prior art fiber composites, the fibers are poorly bonded to the resin matrix, so they are prone to delamination during processing using traditional machines...
