Primary Material EditingThe information of the polishing wheel is slightly different from that of the polishing wheel. It is made of various cotton fabrics, fine felt, silk, deer skin, sisal, horse hair, etc. with better elasticity. In addition, cloth wheels made of special paper to save cotton and wool fabrics are also widely used.The hardness of the polishing wheel is determined by the spacing between the stitching lines, and the smaller the spacing between the stitching lines, the higher the hardness of the polishing wheel. In order to make the polishing wheel softer, the manufacturing of the polishing wheel should pay attention to maintaining sufficient spacing between the stitching and the wheel edge (there may also be non stitching). Polishing large workpieces also uses polishing wheels with special air cooling devices.

There are several manufacturing methods for polishing wheels:(1) Non stitched fabric wheel. Made with delicate and soft cotton cloth, it is suitable for polishing workpieces with irregular shapes or for fine polishing of small workpieces.(2) Stitching. It is often made of coarse cloth, non-woven fabric, and fine plain cloth. The stitching can be done using concentric spiral and direct radiation methods. It is suitable for polishing various coatings and simple shaped work.(3) Air cooled cloth wheel. Using a 45 degree angle wire cutting method, it is in a circular wrinkled shape with a metal disc in the middle, which has the characteristic of ventilation and heat dissipation. It is suitable for polishing large workpieces.(4) Felt wheel. Made of pure wool, it has a long shrinking time, tight arrangement, and small pores, unlike fabrics that are constrained by warp and weft, and has good wear resistance.There are several types of materials classified according to their primary use:(1) Sandcloth wheel. Made of sandcloth with different particle sizes and abrasives (such as corundum and silicon carbide). Its high cutting rate is suitable for grinding, polishing, deburring, and precision machining of various types of materials.(2) Cotton polishing wheel. Made of different types of cotton cloth. Using different impregnation methods and abrasives, it can be used for semi polishing, polishing, and mirror polishing.(3) Mixing and polishing wheels of hemp and cotton. Choosing hemp cloth or lining with cotton cloth generally requires immersion treatment, and with the help of various abrasives, initial polishing and polishing can be carried out.(4) Composition information - non-woven polishing wheel. The composition materials often use nylon wire, adhesives, and abrasives to make non-woven fabrics, which are used as raw materials to make various shapes of polishing wheels. Due to their inherent abrasive content, there is generally no need for grinding agents, and they are mostly used for polishing.(5) Special material polishing wheel.
