Cutting tools are mostly used to cut metal materials, but there are also some tools used to process composite materials. An existing cutting tool is used to realize the hole processing of glass fiber-aluminum honeycomb composite materials. The existing cutting tools The cutting tool is generally a round rod structure, and one end of the round rod structure is provided with a tooth-shaped cutting edge, and the cutting edge of the tooth-shaped structure at the end is generally arranged radially along the circumference of the round rod-shaped structure. Using a cutting tool to process the holes of glass fiber-aluminum honeycomb composite materials has the following disadvantages: first, the surface of the processed material is not smooth enough, and prone to flanging and burrs; second, the fibers inside the material are easily damaged

Embodiment
[0024] Such as Figure 1 to Figure 5 Shown, a kind of end-tooth cutting tool with cutting edge on the circular arc of the present invention comprises a round rod-shaped cemented carbide body 1; One end of this round rod-shaped cemented carbide body 1 is provided with cutting edge 2, The other end of this round rod-shaped cemented carbide body is set as handle 3; The cutting edge 2 is formed by an end-toothed cutting edge located at a section of arc on the circumference of one end of the round rod-shaped cemented carbide body. 21; the projection of the cutting edge from one end of the round rod-shaped cemented carbide body to the direction of the handle forms a crescent shape 22.
[0025] In this embodiment, there are multiple end-toothed cutting edges 21 at the section of the arc, of course, there may also be one end-toothed cutting edge at the section of the arc.
[0026] In this embodiment, the lines connecting the top ends of the plurality of tooth-shaped cutting edges 21 ...

Abstract
The invention discloses an end tooth cutting tool with a cutting edge on the circumference arc. The end tooth cutting tool comprises a round-bar-shaped hard alloy body. The cutting edge is arranged at one end of the round-bar-shaped hard alloy body, and a tool handle is arranged at the other end of the round-bar-shaped hard alloy body. The cutting edge is composed of an end-tooth-shaped cutting edge at a section of arc on the circumference at the end of one end of the round-bar-shaped hard alloy body. The projection of the cutting edge from the end of one end of the round-bar-shaped hard alloy body to the handle direction is in a crescent shape. By means of the structure improvement, when machining of a glass fiber-aluminum honeycomb composite hole, the surface of a machined material is flat, the phenomena of flanging and burrs are avoided, fiber in the material is not damaged, and the end tooth cutting tool has the characteristics of being high in hole wall quality and hole precision.
Description
technical field [0001] The invention relates to a cutting tool, in particular to an end-tooth cutting tool with cutting edges on the circular arc of the circumference. Background technique [0002] Cutting tools are tools used for cutting in mechanical manufacturing. The structure of various tools is usually composed of a clamping part and a working part. The working part of the tool is the part that generates and processes chips, including cutting edges, breaking or rolling chips Structural elements such as the structure of the tool, the space for chip removal or chip storage, the channel of the cutting fluid, etc. For the overall structure tool, the clamping part and the working part are all made on the tool body. Cutting tools are mostly used to cut metal materials, but there are also some tools used to process composite materials. An existing cutting tool is used to realize the hole processing of glass fiber-aluminum honeycomb composite materials. The existing cutting to...
