Aluminium Mechanical Polishing

The Process

Mechanical polishing is a precision finishing technique designed to smooth and refine the surface of aluminium components using specialised mechanical tools and abrasives. The process involves multiple stages, each utilising progressively finer abrasives to achieve the desired level of smoothness and surface quality.

The process typically begins with linishing, where the component is brought into contact with a rotating linishing belt to remove imperfections, scratches, and surface irregularities. The belt is available in various grit grades, ranging from coarse to fine, depending on the amount of material that needs to be removed.

Following linishing, the surface can be further enhanced through mopping or buffing, which imparts a brighter, more polished appearance. This is achieved by applying the component to a rotating mop or buffing wheel, which is attached to a spindle driven by a lathe. The combined action of linishing and buffing ensures a uniformly smooth and aesthetically appealing finish.

The precision polishing process not only removes surface material but also induces a degree of surface deformation, resulting in a refined modification of both the macroscopic and microscopic texture of the aluminium. This ensures optimal surface characteristics for a wide range of applications.

Benefits of Mechanical Polishing

Mechanical polishing provides several key advantages, making it an essential process for industries requiring high-quality aluminium finishing:

✔ Enhanced Surface Finish – Achieves a smoother and more uniform surface, reducing roughness and imperfections.

✔ Reduced Product Adhesion – Minimises surface irregularities, preventing unwanted material buildup and improving performance in critical applications.

✔ Improved Surface Cleanability – Creates a refined surface that is easier to clean and maintain, making it ideal for industries requiring hygienic or contamination-resistant components.

✔ Superior Aesthetic Appeal – Produces a visually polished and professional finish, enhancing the overall appearance of aluminium parts for decorative or high-end applications.
