AmaCupid Elastic Polyurethane Buffing wheel 3 Inch 2000 Grit. for Mini Small Bench Grinding Polishing Machine. Home DYI, Jewelry, Stainless Steel and Other Metals. 3/8 Arbor

Applications: Precision polishing of surfaces made from non-ferrous metals and various non-metallic materials. Examples include mirror-finish polishing for automotive parts, golf club heads, mobile phone casings, glass, gemstones, and marble, as well as the removal of oxide layers prior to coating. High-grit polyurethane polishing wheels provide a finishing touch after initial polishing with cloth or fiber wheels, imparting a premium look and feel to the product Product Features: Polyurethane polishing wheels offer exceptional wear resistance and good self-sharpening properties. They contain silicon carbide abrasive, ensuring sharpness and durability. They feature a uniform microporous structure, excellent toughness, and superior elasticity. During polishing, abrasive particles detach directly without generating dust. They offer a long service life and deliver outstanding polishing results, performing equally well in both dry and wet applications Product Specifications: Polyurethane polishing wheel with a diameter of 3 inches (75 mm), a 3/8-inch (10 mm) bore, a thickness of 1/2 inch (20 mm), a hardness of 70A (Shore), and a grit of 2000. Please select the appropriate polyurethane polishing wheel based on your machine's spindle diameter and rotational speed; these wheels are often used in conjunction with lubricants. They offer greater durability and finer polishing results compared to cloth, fiber, or wool wheels, and can partially replace sandpaper and abrasive nylon wheels Safety and Precautions: The rotational speed for polyurethane polishing wheels is typically 1,500–3,000 rpm. Select the appropriate speed and pressure for the polishing operation. Begin polishing at a low speed and with light pressure; use a low speed specifically for thin-walled parts, as excessive speed can easily burn the workpiece. During the process, move the polishing point quickly to prevent burning the workpiece and to ensure uniform polishing After-sales Service: Every product undergoes inspection and packaging, though unforeseen issues can occasionally occur.
