Polycrystalline diamond tool for machining excircles and inner holes of copper materials of all types

Abstract

The invention provides a polycrystalline diamond tool for machining excircles and inner holes of copper materials of all types, and belongs to the technical field of superhard tools. The polycrystalline diamond tool for machining excircles and inner holes of copper materials of all types solves the problem that polishing on copper materials cannot be omitted with an existing polycrystalline diamond tool. The polycrystalline diamond tool for machining excircles and inner holes of copper materials of all types comprises a tool body and a blade, wherein the cutting edge of the blade is a large fillet, and the radius of the large fillet ranges from 1.0 mm to 1.4 mm; the blade has a dual compound top rake, so that the top rake between the active face and the horizontal plane ranges from 2 degrees to 10 degrees, and the left dip angle b between the active face and the horizontal plane ranges from 5 degrees to 15 degrees; a sideway chip removal guide is arranged on the side face of the blade and comprises a planar chip guiding plane and a cambered chip outlet cambered surface connected with the chip guiding plane, and a wiper is arranged on the edge of the active face of the blade. With the polycrystalline diamond tool for machining excircles and inner holes of copper materials of all types, copper workpieces can be machined without polishing or cooling liquid.

Description

technical field [0001] The invention belongs to the technical field of superhard tools, and relates to a polycrystalline diamond tool, in particular to a polycrystalline diamond tool used for machining outer circles and inner holes of various copper materials. Background technique [0002] In the 1970s, people used high-pressure synthesis technology to synthesize polycrystalline diamond, which solved the problem of scarcity and high price of natural diamond, and expanded the application range of diamond tools to aviation, aerospace, automobile, electronics, stone, etc. field. In addition to mechanical clamping and bonding methods, the combination of polycrystalline diamond composite sheet and cutter body is mostly to press the polycrystalline diamond composite sheet on the cemented carbide cutter body by brazing. Polycrystalline diamond tools are often used in workpieces. of finishing. [0003] Yuhuan County, Taizhou City, Zhejiang Province is the processing base of plumbi...

AI Technical Summary

Problems solved by technology

At present, in order to make the surface of the valve body and connecting pipe fittings made of copper materials bright and convenient for plating, the copper materials will be polished. However, manual polishing is very harmful to the human body. Many people know that copper powder is harmful to the body, but for many reasons The reason is that there are still many people involved in this work, and their wages can be 4-5 times higher than that of machining operators, but they use their bodies to gamble. The current polycrystalline diamond tools cannot realize the free polishing of copper materials processing
