Manufacturing method of heavy-duty grinding resin wheel

Abstract

The invention provides a manufacturing method of a heavy-duty grinding resin wheel. The method comprises the steps that 70 to 90 percent of abrasive, 5 to 20 percent of binder and 5 to 10 percent of filler by mass percent are mixed and uniformly stirred, so as to form mixed material; the mixed material is added into a grinding wheel die which is preheated to 120 to 185 DEG C in batches, and a wire mesh is laid between each two batches of the mixed materials, so as to form a grinding wheel initial blank; the grinding wheel initial blank is subjected to hot press molding; a grinding wheel subjected to hot press molding is put into a grinder, and the end surface of the grinding wheel is ground till the abrasive on the surface of the grinding wheel can be seen; and the grinding wheel subjected to grinding treatment is calcined and then naturally cooled to room temperature, so that the heavy-duty grinding resin wheel is obtained. The heavy-duty grinding resin wheel is unlikely to rupture, edges are unlikely to drop off, and the heavy-duty grinding resin wheel is unlikely to crack.

Description

technical field [0001] The invention relates to the technical field of cutting and grinding grinding wheels for machining, in particular to a method for manufacturing heavy-duty grinding resin grinding wheels. Background technique [0002] Heavy-duty grinding resin grinding wheel refers to the resin grinding wheel with a diameter between Φ500mm~Φ1100mm, a thickness of 35mm~120mm, and a working line speed of 80m / s~120m / s. The grinding wheel is installed on a heavy-duty grinding wheel grinder and is mainly used for cutting and grinding steel ingots, billets, steel plates and other materials produced by large iron and steel enterprises. Objectively, the grinding wheel should have the characteristics of high strength, good heat resistance, sharp grinding, good heat conduction and heat dissipation, and high durability. [0003] The manufacturing method of the heavy-duty grinding resin grinding wheel in the prior art is to mix abrasives, adhesives and fillers in a certain proport...

AI Technical Summary

Problems solved by technology

In this method, the strength of the glass fiber mesh placed between the materials is still not large enough, and the mixing ratio between the abrasive, the adhesive and the filler has not always reached a suitable ratio, etc., resulting in

[0004] The strength of the manufactured grinding wheel is still not high enough, and the heat resistance is not good enough. As a result, during the grinding process, the phenomenon of grinding wheel bursting, edge falling, and cracking often occurs, which affects the grinding effect and efficiency, and cannot guarantee safe production.
