Vibrating rough grinding and polishing machines are machines that are mainly used for surface treatment of workpieces. These machines use a vibrating platform to move the workpiece while applying an abrasive or polishing agent to the surface. Vibrating rough grinding involves placing the workpiece on the vibrating platform and applying a coarse abrasive to smooth the surface and remove imperfections. This type of grinding is often used in the production of moldings and castings. Polishing machines with a vibrating platform are used to create a smooth and shiny surface on workpieces. The workpiece is placed on the vibrating platform and polished with a polishing agent to produce a high-gloss surface. This type of polishing is often used in the manufacture of jewelry, watches and other high-end products where a perfect surface finish is required. Vibrating rough grinding and polishing machines are usually automated machines that can process a large number of workpieces in a short time. They are available in many different sizes and configurations and can be used to process a variety of materials including metal, plastic, wood and glass. Overall, vibratory rough grinding and polishing machines are useful tools in the manufacturing industry because they can process workpieces quickly and effectively while achieving high surface quality.
