Flexible abrasive wheel and wheel blank of flexible abrasive wheel

Abstract

The present invention discloses a soft grinding wheel blank and a soft grinding wheel. The soft grinding wheel comprises an installing sleeve and a grinding wheel body. The grinding wheel body consists of bar sand-planted cloth wrapped around the installing sleeve. The adjacent sand-planted cloth is bonded as a whole by bond. The bar sand-planted cloth is molded sand-planted cloth which is made from soft bar cloth material as a substrate, and a single surface is planted with sands. The grinding wheel body of the present invention is made by wrapping the sand-planted cloth, and each layer is bonded with each other, so the soft grinding wheel has good integrity and also has certain flexibility, thereby avoiding the problem of grinding wheel cataclasm, preventing the potential safety hazard caused by the cataclasm, improving the grinding force and the grinding tolerance of the grinding wheel and greatly improving the grinding efficiency of the grinding wheel.

Description

technical field [0001] The invention relates to a flexible grinding wheel and a flexible grinding wheel blank, belonging to the technical field of coated abrasive tools. Background technique [0002] Abrasives are grinding tools widely used in the machining industry, and are mostly used for rust removal, grinding and polishing of metal workpieces. Traditional abrasives are divided into bonded abrasives, super abrasives and coated abrasives. Consolidated abrasives are divided into ceramic abrasives, resin abrasives, rubber abrasives, etc.; super abrasives are divided into diamond abrasives, cubic boron nitride abrasives, etc.; coated abrasives are divided into cotton cloth-based products, blended cloth-based products, polyester fabric products, etc. With the development of the world economy, especially the high-speed development of my country's economy for several consecutive years, social needs are also undergoing tremendous changes. For abrasive tools, it is also develop...

Problems solved by technology

Its disadvantage is that due to the limited structure, it can only be used for profile polishing; in addition, when this type of abrasive tool is operated at high speed, the abrasive cloth sheet is easily separated from the circular base plate due to frictional resistance and centrifugal force, so there is a safety hazard. Hidden danger: The product structure determines that the abrasive cloth can only be assembled in a single piece, which consumes a lot of manpower and time, the production process is relatively cumbersome, and the working environment is not good, which affects the health of workers

[0004] The combination of superhard abrasives and bonded abrasives is limited, and they are prone to fragmentation under excessive external force and high-speed conditions, resulting in personal equipment accidents, and these two abrasives need high-temperature firing during the manufacturing process, which not only It consumes a lot of energy and pollutes the environment
