Overview of Metal Aftertreatment Process - Polishing Process

The polishing process is mainly divided into three categories:                                                             

• mechanical polishing,                                                                                                                                                                                                     
• chemical polishing,
• electrolytic polishing.

The characteristics of these three types of polishing methods are as follows:

1. Mechanical polishing: Using mechanical friction and the difference in particle size of abrasives, gradually removing the rough layer on the metal surface until a smooth and shiny effect is achieved. Easy to operate, relatively low cost, but may cause minor scratches on the surface, suitable for various metal materials.
2. Chemical polishing: By reacting chemical reagents with metal surfaces, the raised parts of the surface are dissolved, making the surface smooth. It can handle complex shaped parts and achieve high glossiness, but the cost is high and may have a certain impact on the environment.
3. Electrolytic polishing: Using the principle of electrochemical reaction, the protruding parts of the metal surface are dissolved through electrolytic action in the electrolyte, achieving a smooth and bright effect. High efficiency, suitable for large-scale production, and capable of handling high hardness metal materials.
