An Electroplated Diamond Tool for Drilling Fiber Reinforced Composite Materials

Abstract

The invention discloses a diamond-electroplated tool for drilling of a fiber reinforced composite material. The diamond-electroplated tool comprises a cylindrical tool rod. A tool bit with the surface electroplated with diamond particles is arranged at the front end of the tool rod. The tool bit comprises a plurality of cutting parts and a plurality of chip discharge grooves. The cutting parts and the chip discharge grooves are evenly distributed in the radial direction and arranged in a staggered manner in the circumferential direction. The outer surfaces of all the cutting parts are part of the same cylindrical face. The cutting parts are located at the front end of the tool bit, and the length of the chip discharge grooves is equal to that of the tool bit. Each cutting part comprises a rear tool face and a front tool face. The rear tool faces coincide with the end face where all the cutting parts are located. The front tool faces and one side faces of the chip discharge grooves are coplanar. The normal direction of the front tool faces is consistent with the rotating linear speed direction of the tool bit. Arc main cutting edges are arranged at the cross positions of the front tool faces and the rear tool faces. A plurality of chip pre-storage grooves communicated with the chip discharge grooves are formed in the center of the end of the tool bit. According to the tool, the phenomenon that in the prior art, during drilling machining of a fiber reinforced composite material, layering, tearing, burrs and the like are likely to occur can be eliminated.

Description

technical field

[0001] The invention relates to a drilling tool, in particular to an electroplated diamond tool used for drilling fiber-reinforced composite materials. 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 ...
