Embodiment Construction

[0022] The present invention will be described in detail below, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0023] The preparation technology of diamond grinding wheel sheet, it comprises the following steps:

[0024] First, prepare titanium dioxide sol, and clean the diamond particles; when cleaning, the diamond particles are first soaked with hydrochloric acid solution, then rinsed with deionized water until the pH value of the rinse solution is 7, and dried, then ultrasonically cleaned with acetone, and then washed with Rinse with deionized water and then dry, which can avoid the introduction of impurities when coating the film and reduce the performance of diamond.

[0025] Then put the cleaned diamond particles on the screen in the device chamber, and then pump the above-mentioned titanium dioxide sol into the device chamber, so that the sol is immersed in the ...

Abstract

The invention relates to a preparation process of a diamond grinding wheel sheet, which comprises preparing titanium dioxide sol, cleaning diamond particles; placing the cleaned diamond particles on a screen in a device chamber, then pumping the above titanium dioxide sol into the device chamber, and extracting the titanium dioxide sol in the device chamber , collect diamond particles through a sieve, dry them, and heat them after cooling to obtain diamond abrasives. The above-mentioned diamond abrasives are transported to a ball mill through a rotating shaft and mixed with nickel-chromium alloy powder, silicon carbide powder and sodium bicarbonate powder for ball milling and screening. , to obtain a mixture, and then put the mixture in a mold for compression molding and sintering to obtain a diamond grinding wheel sheet. In the present invention, after the diamond particles are placed on the screen, the titanium dioxide sol can be pumped into the device chamber, so that the sol is submerged in the screen to ensure that the diamond particles are immersed in the sol, and then the sol in the pump chamber can be conveniently collected through the screen. Sol diamond particles, improve production efficiency.

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, ...
