Preparation process of diamond grinding wheel

Abstract

The invention relates to a preparation process of a diamond grinding wheel. The preparation process comprises the following steps: preparing titanium dioxide gel, and cleaning diamond granules; putting cleaned diamond granules on a screen net inside a device chamber; pumping the titanium dioxide gel into the device chamber, sucking out the titanium dioxide gel inside the device chamber, collecting diamond granules through the screen net, drying, cooling, performing thermal treatment so as to obtain a diamond grinding material, conveying the diamond grinding material to a ball mill through a rotating shaft, performing mixing ball milling with nickel-chromium alloy powder, silicon carbide powder and sodium bicarbonate powder, screening so as to obtain a mixed material, further performing mold pressing molding on the mixed material in a mold, and sintering, thereby obtaining the diamond grinding wheel. According to the preparation process, the diamond granules are placed on the screen net, then the titanium dioxide gel can be pumped into the device chamber, the screen net is submerged by the gel, the diamond granules are soaked in the gel, the gel inside the device chamber is pumped out, diamond granules with the gel can be conveniently collected through the screen net, and then the production efficiency is improved.

Description

technical field [0001] The invention relates to a preparation process of a diamond grinding wheel sheet. Background technique [0002] Diamond grinding tools represented by diamond have developed rapidly, and their applications have penetrated into mechanical processing, automobile manufacturing, aerospace, biology, medical equipment, electronic information, construction, transportation, geological mining and other fields. At present, most of the artificially synthesized diamonds are in the form of powder or fine particles. In order to use diamonds for high-precision and high-efficiency grinding, bonding agents are usually used to bond diamond abrasive grains and make them with a certain strength and The shape of the mold is easy to install on various grinding machines for grinding. Compared with other abrasives such as corundum and silicon carbide, when grinding with a diamond die, it has the advantages of high grinding efficiency, long service life, small grinding force, ...
