Stone graving knife capable of achieving ordered arrangement for diamond brazing, and preparation method

Abstract

The invention discloses a stone graving knife capable of achieving ordered arrangement for diamond brazing, and a preparation method, and belongs to the technical fields of tools. The stone graving knife is divided into a working part, that is, a knife bit, and a clamping part, that is, a knife handle, wherein the working part is composed of a steel matrix of a core part, and nickel-based brazing filler metals and monocrystal diamonds on the surface; the clamping part is composed of a steel matrix and forms an integrated structure with the steel matrix of the core part of the working part; the monocrystal diamonds on the surface of the working part are in a state of ordered arrangement; and the nickel-based brazing filler metals are used for connecting and fixing the monocrystal diamonds and the matrixes. The stone graving knife and the preparation method, which are disclosed by the invention, have the following advantages: during realization for the uniform distribution and ordered arrangement of the diamonds, optimization for the spacing of the diamonds can be realized according to the differences of abrasion cutting objects and abrasion cutting conditions, and at this moment, the diamonds can be effectively utilized, a cutting effect can be exerted, and adequate chip removal and washing cooling can be achieved; and moreover, the connection strength of the diamonds and the matrixes is high, and the optimization purpose of prolonging the life of the tool while increasing the abrasion cutting efficiency can be realized.

Description

technical field [0001] The invention relates to an orderly arranged diamond brazing stone carving knife and a preparation method, belonging to the technical field of cutting tools. Background technique [0002] The conventional diamond brazed stone carving knives on the market are all randomly and disorderly arranged diamond abrasive grains on the tool base. In the process of stone carving, the amount of undercut changes rapidly and three-dimensionally with the engraving pattern. When the knife is cut quickly to a certain depth, it is very easy to have difficulty in chip removal, and it is difficult for the cooling water to cool the end of the cutter head, resulting in difficulty in undercut and frequent knife burning And other issues. [0003] There are existing diamond brazed stone carving knives on the market, which are prone to insufficient cooling and difficult chip removal during use, which seriously affects the sharpness of the knives and causes the problem of burnin...

AI Technical Summary

Problems solved by technology

[0004] For conventional diamond brazing engraving knives, the random and disordered arrangement of diamonds in the metal matrix makes diamonds prone to segregation and aggregation in the tool body

In the diamond-enriched area, the diamond concentration is high, and the grinding force of a single diamond is small, so it is easy to be polished and worn. Under heavy workload, diamonds are easy to break and fall off. Therefore, the disordered arrangement of diamond engraving knives has the problems of low grinding efficiency, short tool life and conflicting grinding efficiency and life.
