A Guide To Polishing: What Polishing Wheel To Use For Which Material
What Are Polishing Wheels?
Polishing Wheels, also known as buffing wheels, provide a smooth and clean finish to metals, plastics, jewellery, glass, ceramic, wood, etc. They are mounted on polishing and grinding machines and rotated at high speeds to acquire the desired finish. Different types of polishing and grinding wheels are used for other purposes and have different results.
To get the desired finish, you must use the correct polishing wheel. However, that isn’t the only substance required for the final product. The process is two-fold. The first step is choosing the correct polishing/grinding wheel, and the second is associating it with the proper polishing compound. The polishing compound must be spread evenly on the wheel, and then the wheel, now coated with the compound, together to help you reach your end product.

·        Glass and Stone: Polishing glass, marble, and other stone surfaces. ·        Metal Polishing: Suitable for polishing metals to a high shine, including steel, stainless steel, and aluminium. ·        Abrasive Compounds: Often used with abrasive compounds for more aggressive polishing. |
| Satin/Matte |  |
·        Satin Finishes: These are used to create satin or matte finishes on metals and other materials.
·        Deburring: Effective for deburring edges and surfaces of metal parts. ·        Surface Preparation: Prepares surfaces for further finishing processes such as painting or plating. ·        Aesthetics: Provides an aesthetic finish for architectural and decorative purposes. |
| Aluminium Oxide |  |
·        Aggressive Cutting: Suitable for aggressive cutting and material removal.
·        Hard Metals: Used for polishing and finishing hard metals such as stainless and high-carbon steel. ·        Surface Cleaning: Effective for cleaning oxidised or corroded surfaces. ·        Tool Sharpening: Commonly used in tool sharpening and blade honing applications. |
| Silicon Carbide |  |
·        Hard Material Polishing: Ideal for polishing and grinding hard materials like ceramics, stone, and glass.
·        Aggressive Material Removal: Effective for rapid material removal and shaping. ·        Non-Ferrous Metals: Suitable for non-ferrous metals such as aluminium, brass, and bronze. ·        Surface Preparation: Used for surface preparation tasks before finishing. |
| Nylon and Wire Wheels |  |
·        Surface Cleaning: Used for cleaning and removing rust, paint, and other surface contaminants.
·        Deburring: Effective for deburring and edge blending on metal parts. ·        Texturing: Can be used to create a textured surface finish on metals and other materials. ·        Woodworking: Nylon wheels can be used for surface finishing and texturing in woodworking. ·        Welding Preparation: Wire wheels are commonly used to prepare surfaces for welding by removing oxides and other contaminants. |
