Resin grinding wheel and preparation method thereof

Abstract

The invention discloses a resin grinding wheel and a preparation method for the resin grinding wheel. The resin grinding wheel is made of the following raw materials of brown aluminium oxide, inorganic heat conducting fillers, iron sesquioxide, boric acid, polyvinyl alcohol, phenol, a formaldehyde solution with the concentration being 35-40%, a phenolic resin solution and kryocide. The resin grinding wheel has high hardness and impact resistant toughness and good self-sharpening and performs heat dissipation quickly.

Description

technical field [0001] The invention belongs to the technical field of grinding tool processing, and in particular relates to a resin grinding wheel and a preparation method thereof. Background technique [0002] Resin grinding wheel is a grinding wheel whose binder is resin. It has the advantages of small grinding force, low grinding temperature, good self-sharpening, and high grinding efficiency. It is widely used in the grinding of hard and brittle materials such as cemented carbide, ceramics, and glass. In processing, it is the preferred grinding wheel for cutting stainless steel plates. The grinding wheel will inevitably generate cutting heat during use. If the cutting heat cannot be transmitted out in time, it will cause heat accumulation, which will not only damage the workpiece, but also cause the resin bond of the grinding wheel to be carbonized, resulting in brittle cracking of the grinding wheel.
