The hardness of the polishing wheel is determined by the spacing of the sutures. The smaller the spacing of the sutures, 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 using polishing wheels with special air-cooled equipment.There are several manufacturing methods for polishing wheels:(1) Non stitched fabric wheel. It is often made of soft cotton cloth and 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 in the form of concentric spiral or direct radiation. It is suitable for polishing various coatings and operations with simpler shapes.(3) Air cooled cloth wheel. Using a 45 degree angle cutting method, it is in a circular and wrinkled shape, with a metal disc installed in the center, which has the characteristics of ventilation and heat dissipation. It is suitable for polishing large workpieces.(4) Felt wheel. Made from pure wool, it has a long shrinking time, tight organization, and small pores, unlike fabrics that are limited by warp and weft, and has good wear resistance.

According to the main material categories, there are the following:(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 from different varieties 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 impregnation treatment, and various abrasives can be used for initial polishing and polishing.(4) Composition information - non-woven polishing wheel. The composition materials often use nylon thread, adhesives, and abrasives to make non-woven fabrics, which are used as raw materials to make various shapes of polishing wheels. Due to the presence of abrasives, they generally do not require abrasives and are mostly used for polishing.(5) Special material polishing wheel.
