Embodiment 1

[0035] Such as figure 1 , figure 2 As shown, a high-speed self-sharpening CBN grinding wheel for processing unquenched alloy steel workpieces includes a steel substrate 1, an abrasive block 2 bonded to the steel substrate and an auxiliary grinding self-sharpening block 3, wherein the abrasive block and the auxiliary The grinding self-sharpening blocks are distributed at intervals. Abrasive agglomerate length is 38.7mm, forming density is 2.32, auxiliary grinding self-sharpening agglomerate length is 16.7mm, forming density is 2.48; if abrasive agglomerate and auxiliary grinding self-sharpening agglomerate have the same length, the performance will be worse, processing After 1300 pieces, sticky chips appeared.

[0036] The raw material composition and weight percentage of the abrasive block are: 80 / 100 grain size CBN abrasive 57%, vitrified bond 36%, phenolic resin liquid 7%; the auxiliary grinding self-sharpening block raw material composition and weight percentage are: 80 / ...

Abstract

The invention discloses a high-linear-speed self-sharpening CBN grinding wheel for processing unquenched alloy steel parts and a preparation method thereof. The high-linear-speed self-sharpening CBN grinding wheel comprises a steel base body, abrasive blocks and auxiliary grinding self-sharpening blocks, wherein the abrasive blocks and the auxiliary grinding self-sharpening blocks are bonded to the steel base plate and alternately distributed. According to the high-linear-speed self-sharpening CBN grinding wheel, the auxiliary grinding self-sharpening blocks are added creatively so that the superhard CBN grinding wheel can replace a common abrasive grinding wheel for being used for processing the unquenched steel parts. The linear speed of the grinding wheel can reach 120 m / s during application. Scraps are not likely to adhere to the grinding wheel, and the unquenched parts are not likely to be burned. The high-linear-speed self-sharpening CBN grinding wheel has the advantages of beinglong in trimming interval and service life, high in efficiency and good in stability and is suitable for an automatic production line.

Description

technical field [0001] The invention belongs to the technical field of grinding wheels for mechanical processing, in particular to a high-speed self-sharpening CBN grinding wheel for processing unquenched alloy steel workpieces and a preparation method thereof. Background technique [0002] With the development of the mechanical processing industry, the requirements for high efficiency, high precision, and high quality are getting higher and higher. Superabrasive abrasives are more and more used in various grinding processing fields because of their high hardness and long life. CBN grinding wheels have gradually replaced traditional corundum grinding wheels, but the high hardness of CBN abrasives can only have greater advantages at high line speeds. Unquenched alloy steel is not suitable for high-speed processing of high-hardness CBN grinding wheels due to its high toughness and easy to burn chips during processing, so ordinary abrasive grinding wheels are still used in the ...
