Polishing wheels are tools used to enhance the surface finish of various materials, including metals, plastics, and wood. They are typically made from materials like felt, cotton, or synthetic fibers and are attached to a rotating machine, such as a bench grinder or a polishing lathe. The wheels work by applying a polishing compound that helps to remove scratches and imperfections, resulting in a smooth and shiny surface. These wheels come in different sizes and grades, allowing users to choose the right one for their specific project. Common applications include automotive detailing, jewelry making, and woodworking. Proper use of polishing wheels can significantly improve the appearance and longevity of the finished product.
