Method for making abrasive tool with cooperative arrangement of abrasive particles by brazing

Abstract

The invention discloses a method for manufacturing an abrasive tool with abrasive particle collaborative configuration by virtue of brazing, which comprises the following steps: 1) carrying out pretreatment on abrasive materials and a steel substrate; 2) smearing binder onto the surface of the steel substrate uniformly; 3) configuring two kinds of abrasive materials on the surface of the binder according to a corresponding geometric structure; 4) covering the surroundings of the abrasive materials with brazing filler metal, putting into a vacuum furnace, heating at a high temperature, and cooling so as to obtain the abrasive tool. According to the method, diamond and cubic boron nitride are preferably adopted as abrasive materials for manufacturing the brazing tool with abrasive material collaborative configuration by virtue of high-temperature brazing; the excellent thermal expansion performance of the brazing filler metal (Ag-Cu-Ti brazing filler metal and Cu-Sn-Ti brazing filler metal) is utilized to make up the thermal expansion difference of the steel substrate, the alloy brazing filler metal and the abrasive materials, the brazed connection of the abrasive materials and the steel substrate is successively realized, and the application field of the brazing abrasive tool is broadened.

Description

technical field

[0001] The invention discloses a method for making abrasive tools by high-temperature brazing of brazing filler metal, in particular using Ag-Cu-Ti brazing filler metal and Cu-Sn-Ti brazing filler metal to realize the brazing connection of two kinds of cooperatively arranged abrasive materials on a steel substrate The method belongs to the technical field of high temperature brazing. Background technique

[0002] According to processing theory, the processing performance of abrasive tools is determined by two aspects: one is the ability of the abrasive grains to carry loads, that is, the strength of the abrasive and the ability of the bond to hold the abrasive; the other is the shape of the abrasive grains. It is critical for single-layer bonded abrasive tools.

[0003] In recent years, high-temperature brazing abrasive tools have made great progress. It is a kind of nickel-based, silver-based, and copper-based brazing abrasives using brazing filler metals, ...
