85 | Published by Lichuang at Jul 07, 2025

Polyurethane polishing wheels are specialized polishing tools made from polyurethane material through a unique foaming process. Featuring a uniformly distributed microcellular structure, these wheels combine elasticity with wear resistance, making them suitable for a wide range of industrial applications. With consistent particle size and high stability, they significantly enhance polishing efficiency while reducing overall costs.
In terms of functionality, polyurethane polishing wheels are ideal for surface treatment of various metal materials, including stainless steel, iron, copper, and more. They effectively perform tasks such as grinding, polishing, deburring, cleaning, and rust removal. Available in multiple specifications, these wheels can be customized with features like velcro backing, adhesive backing, multi-hole designs, or grooved to accommodate different equipment requirements. The typical hardness range is between 30° and 95°, with grit sizes spanning from 60 to 5000 and diameters ranging from 75mm to 150mm. Users can select the appropriate hardness and grit size based on the specific material being polished, enabling precise and versatile polishing results.
Polyurethane polishing wheel are compatible with various flat polishing equipment and 5-axis polishing machines. During use, a water-cooling system is recommended to prevent material deformation or reduced polishing effectiveness caused by high temperatures. This cooling method also helps extend the wheel’s service life and ensures consistent processing stability.

From an industry perspective, polyurethane foam polishing wheels deliver outstanding performance across multiple sectors. In 3C electronics manufacturing, they are used for fine polishing of components such as smartphone frames and casings. In the automotive industry, they are applied to engine parts, transmission components, and other precision metal accessories to effectively remove machining marks like mill lines and fish-scale patterns. In aerospace, these wheels meet the demands of high-strength, high-precision surface treatment. Additionally, they are widely used in shipbuilding, precision instruments, hardware tools, and other industries.
