Polishing is an indispensable processing technique for the production of sofa legs, though it generates a considerable amount of dust during the process.

 

Polishing refers to the mechanical, chemical, or electrochemical actions that reduce the surface roughness of a workpiece to achieve a smooth, lustrous finish (and sometimes to eliminate glossiness).

 

This method is extensively applied across various industries, including consumer electronics like mobile phones, furniture hardware accessories, automobiles, and more.

 

In the context of metal surface treatment for sofa legs, polishing is a significant fabrication technology. It involves manual and mechanical methods to remove the microscopic irregularities from the metal surface, enhancing its smoothness and corrosion resistance.

 

 

The mechanical polishing process in metal surface treatment includes the following steps:

Preparation: Clean the metal surface, removing oil and rust.

 

Coarse Grinding: Utilize coarse grinding wheels or sandpaper to initially abrade the metal surface, removing surface defects and rough areas.

 

The objective is to eliminate casting surface and edge burrs, as well as any bruises from the previous process, achieving preliminary corner rounding, and ensuring that the surface is essentially free of major scratches and dents.

 

Fine Grinding: Employ fine grinding wheels or sandpaper for detailed abrasion to further smooth the metal surface. Correct any seams from the previous processes and further refine the marks left by coarse grinding.

 

Repeatedly polish the marks left by previous processes until the casting surface is scratch-free and essentially bright.

 

Precision Grinding: Correct and polish fine lines that appeared in the previous step, using the same polishing methods. The goal of this process is to make the seams with the unpolished parts of the casting essentially disappear, further brightening the casting surface.

 

The casting should nearly achieve a mirror-like effect after this polishing process. During polishing, pay attention to the inclination angle of the sanding machine and control the pressure applied to the workpiece. Generally, maintaining a straight line with the polished surface is moderate!

 

 

Polishing: Use a polishing wheel or polishing compounds to polish the metal surface, enhancing its gloss and aesthetic appeal.

 

Cleaning and Rust Prevention: After polishing is complete, clean the metal surface and take appropriate rust prevention measures to maintain its appearance and prevent corrosion.

 

To achieve high-quality polishing effects, strict quality control over the mechanical polishing process is necessary. Here are some key quality control measures:

 

Process Parameter Control: Strictly control the rotation speed, pressure, and other parameters of the polishing wheel to ensure the stability and consistency of the polishing process.

 

Operator Skill Training: Regularly train and assess operators to ensure they are familiar with the polishing process, master the operation skills, and are quality-conscious.

 

Quality Inspection and Evaluation: Regularly inspect and evaluate the quality of the polished metal surfaces, such as surface flatness, gloss, roughness, and other indicators.

 

 

Equipment Maintenance and Inspection: Regularly inspect and maintain polishing equipment to ensure its normal operation and stability. For example, check the wear of grinding and polishing wheels and replace them in time to ensure processing results.

 

With the continuous emergence and application of new materials, traditional mechanical polishing techniques may not meet the needs of some materials.

 

Therefore, it is necessary to develop new mechanical polishing technologies to adapt to the characteristics of new materials. For instance, nanometer-level ultra-precision machining technology, laser polishing technology, and others will gain wider application.
