Sanding machines are tools used to smooth surfaces by abrasion. They typically use sandpaper or other abrasive materials to remove imperfections from wood, metal, or plastic. These machines come in various types, including belt sanders, orbital sanders, and disc sanders, each designed for specific tasks and materials. These machines are commonly used in woodworking and construction industries, as well as in furniture making. By providing a consistent finish, sanding machines help prepare surfaces for painting, staining, or sealing. Proper use of sanding machines can enhance the quality and appearance of finished products, making them essential in many workshops.
