Embodiment 2

[0025] Embodiment 2: The overall structure is the same as that of Embodiment 1, and the main parameters are basically the same, the only difference is that the plane where the flank face 3 of the arc-shaped cutting part is located is coplanar with the plane where the front end of the frustum-shaped center drill 7 is located, The diameter of the front end of the truncated conical central drill 7 is 1 mm, and the conical angle of the truncated conical central drill 7 is 22°.

Embodiment 3

[0026] Embodiment 3: The overall structure is the same as that of Embodiment 1, and the main parameters are also basically the same. The only difference is that the plane where the front end of the conical center drill 7 is located is 0.5 mm protruding from the plane where the flank face 3 of the arc-shaped cutting part is located. , The diameter of the front end of the frustum-shaped center drill 7 is 1 mm, and the cone angle of the frustum-shaped center drill 7 is 27°.

[0027] The base material of the cutting tool of the present invention is selected as metal material, as No. 45 steel can be selected for use, after quenching and tempering and surface quenching treatment, diamond particles 9 are plated on the surface. The cutting tool of the present invention has high hardness, high strength, good heat resistance and drill Good cutting performance and other advantages.

Abstract

The invention discloses a fiber reinforced composite material perforation cutter based on electroplated diamond. The cutter comprises a cutter bit arranged at the front end of a cutter bar and electroplated with diamond particles on the surface; the cutter bit includes multiple arc cutting parts and multiple chip removing grooves uniformly distributed in the radial direction; the arc cutting parts and the chip removing parts are staggered in the peripheral direction; the outer surfaces of all the arc cutting parts are one part of the same cylindrical surface; a center drill is arranged in a cylindrical space formed by the inner sides of the multiple arc cutting parts; each arc cutting part includes a back cutter surface and a front cutter surface; the back cutter surfaces are overlapped with the end faces, where the back cutter surfaces are positioned, of the corresponding arc cutting parts; the front cutter surfaces and one side surfaces of the chip removing grooves share one surfaces; the normal direction of the front cutter surfaces is consistent with the rotating linear speed of the cutter bit; arc main cutting edges are arranged in the cross places of the front cutter surface and the back cutter surface; and chip pre-storing grooves communicated with the multiple chip removing grooves are formed between the arc cutting parts and the center drill. The cutter can eliminate such phenomenon as easy generation of layering, tearing and burrs during drilling of fiber reinforced composite materials.

Description

technical field [0001] The invention relates to a drilling tool, in particular to a drilling tool based on electroplated diamond fiber reinforced composite material. Background technique [0002] Composite material refers to a material composed of two or more different substances combined in different ways. It has many advantages such as light weight, high specific strength, high specific stiffness, good vibration reduction and fatigue resistance, and corrosion resistance. Used in aerospace, transportation, biomedical and sporting goods and other fields. With the rapid development and wide application of composite materials, the forming and processing of composite parts is becoming more and more important. Drilling is one of the most important processing procedures in the manufacturing process of composite materials. Due to the characteristics of high hardness, high strength, poor thermal conductivity, anisotropy, and low interlayer strength of composite materials, it is ea...
