Sisal buffing wheels are typically used in the intermediate stage of the polishing process to remove scratches left by rough grinding and to achieve a preliminary polishing effect.
It is generally believed that the biggest factor affecting the hardness and cutting power of a sisal buffing wheel is the density of the sisal weave; the denser the weave, the harder the wheel and the stronger its cutting power. However, there is another important factor that affects the cutting power of the sisal buffing wheel: the stitching density. Stitching density refers to the distance between two rows of stitching on the sisal buffing wheel, also known as the pitch. The denser the stitching, the harder the wheel, and the greater the compressive and bending resistance of each sisal fiber during the polishing process, resulting in stronger cutting power.
When the cutting force of the sisal buffing wheel is enhanced, the polishing time required for the same product, using the same polishing techniques and equipment, is correspondingly shortened, greatly improving polishing efficiency. Furthermore, because a higher tooth density results in better cutting force, it not only saves polishing time but also reduces polishing costs. For example, when polishing the same product, we previously needed 1-3 stages of abrasive to rough polish, followed by a regular sisal wheel to remove the sanding marks to achieve a preliminary polished finish; however, now we only need one or two stages of abrasive for rough polishing, and then use a sisal wheel with a higher tooth density to remove coarser sanding marks and achieve the same preliminary polished finish, significantly reducing polishing costs.
This type of sisal buffing wheel with higher tooth density, greater hardness, and stronger cutting force is particularly suitable for polishing hard metal products such as stainless steel.
