Abstract

The invention discloses a metal and ceramic bonding agent and a preparation method of the metal and ceramic bonding agent, a CBN grinding wheel and a manufacturing method of the CBN grinding wheel. The metal and ceramic bonding agent is composed of, by mass fraction, 75%-92% of ceramic and 8%-25% of metal. The ceramic is composed of, by mass fraction, 40%-65% of SiO2, 8%-35% of B2O3, 6%-20% of Al2O3, 5%-18% of Na2O5, 0.5%-5% of CaO, 3%-10% K2O, 0.5%-2% of MgO and 2%-6% of TiO2. The metal is composed of, by mass fraction, 55%-80% of Cu, 15%-30% of Sn and 5%-20% of Ni. The metal and ceramic bonding agent can be used as a CBN grinding wheel bonding agent and overcomes the defects that in the grinding process of the ceramic CBN grinding wheel, the surface roughness of a workpiece is large, chatter marks are generated easily, and impact resistance is poor.

Description

technical field [0001] The invention belongs to the technical field of superhard material products, and in particular relates to a cermet bond and a preparation method thereof, a CBN grinding wheel and a preparation method thereof. Background technique [0002] Compared with ordinary grinding wheels, CBN grinding wheels have the characteristics of high grinding efficiency, good surface finish and high grinding quality. CBN grinding wheel is to use bonding agent to bond CBN abrasive grains and make it into an abrasive tool with a certain strength and shape, which can be used for high-precision and high-efficiency grinding of various metals and alloys. With the needs of rapid industrial development and continuous breakthroughs and innovations in material science, various new materials with high strength, high hardness, corrosion resistance and high temperature resistance have emerged as the times require. These materials are relatively difficult to process, especially in the p...
