Abstract

The invention relates to the technical field of abrasive grinding of grinding tools, and in particular to a compound metal and ceramic bonding agent diamond grinding wheel. The compound metal and ceramic bonding agent diamond grinding wheel is prepared from, by weight, 50-70 parts of surface titanium-coated diamond abrasive, 4-10 parts of tin powder, 10-20 parts of copper powder, 10-18 parts of aluminum powder, 11-18 parts of silicon dioxide, 5-10 parts of boric oxide, 5-8 parts of zinc oxide, 2-6 parts of calcium oxide, 0.01-1 part of lanthanum powder and 1-4 parts of aluminum oxide. Due to the fact that the surface of diamond is coated with titanium so that oxidization resistance can be achieved; titanium is slowly dissolved in a bonding agent in subsequent reactions and forms a transition layer with the diamond abrasive, and therefore the bonding force of the bonding agent on the abrasive is improved; the lanthanum powder is added so that the mechanical performance of a matrix of the grinding wheel can be effectively improved, and the bonding strength of a matrix material on diamond is improved and strengthened; and the aluminum oxide is added so that the pore forming function can be achieved. The compound metal and ceramic bonding agent diamond grinding wheel maintains the good self-sharpening performance of a ceramic bonding agent grinding wheel and also has the good characteristics of high rigidity and good shape maintenance of a metal bonding agent grinding wheel; and formulas are in cooperation, so that the forming performance of the grinding wheel is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of grinding tools and abrasives, in particular to a composite metal-ceramic bonded diamond grinding wheel. Background technique [0002] Grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding agent. Diamond abrasives are used as raw materials, and metal powder, resin powder, and ceramic powder are used as binders respectively. The circular bonded abrasive with a through hole in the center is called a diamond grinding wheel. Due to the characteristics of high hardness, high compressive strength and good wear resistance of diamond abrasives, diamond abrasives become ideal tools for grinding hard and brittle materials and cemented carbide in grinding processing. With the development of science and technology, the performance requirements of diamond grinding wheels are getting higher and higher: the cutting force of the grinding wheel is required to be good and s...
