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

Embodiment Construction
[0025] The structure of the flexible grinding wheel blank of the present invention is as Figure 1~3 As shown, the flexible wide-width cloth-like material 1 is wound around the central hole 4 to form a winding structure, and a layer of abrasive grains 2 is wrapped between adjacent flexible wide-width cloth-like materials 1, and the roots of the abrasive grains 2 are glued to each other. The mixture is evenly bonded on the side of the flexible wide cloth-like material 1 facing the outside, and the top of the abrasive grit 2 is bonded together by point contact with the side of the flexible wide cloth-like material 1 facing the inside through the adhesive, Made into a flexible grinding wheel blank. A mounting sleeve 3 is bonded and fixed in the central hole 4 . The finished flexible grinding wheel blank can be cut into flexible grinding wheels of different specifications according to needs.

The present invention discloses a soft grinding wheel and a soft grinding wheel blank. The soft grinding wheel comprises an installing sleeve and a grinding wheel body. The grinding wheel body consists of soft bar cloth shaped material wrapped around the installing sleeve. A layer of abrasive grit is wrapped between the adjacent soft bar cloth shaped materials. The root of the abrasive grit is bonded at the outer surface of the soft bar cloth shaped material near an inner layer by bond. The top of the abrasive grit is bonded with the inner surface of the soft bar cloth shaped material near an outer layer. The grinding wheel body of the present invention is formed and wrapped by the soft bar cloth shaped material, and the adjacent soft bar cloth shaped materials are all wrapped with a layer of abrasive grit, 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...
