Mechanical Polishing Operation
Mechanical polishing is a process that is used to obtain the highest surface quality possible on a variety of substrates and materials. This process uses abrasive media, a rotatin Mg wheel, and a polishing compound to remove small imperfections, scratches, and dirt from a surface. Mechanical polishing can not only improve the aesthetics of a surface, but can also improve its functionality.
Mechanical polishing begins with the cleaning of the surface. Debris and any unwanted particles need to be removed before polishing begins. There are a variety of ways this can be accomplished and will depend on the type of substrate being polished. If the substrate is metal, it may require a chemical or physical cleaning process.
Once the surface has been cleaned, the next step is to begin the polishing process. This process typically begins with rougher grit media that is used to remove larger imperfections from the surface. As the grit size decreases, the abrasive media becomes finer and will start to remove smaller imperfections. It is important to remember to use the same rotation on the grinding wheel for each application of media.
When using a grinding wheel and abrasive media, it is important to use the correct type. Different types of materials require different types of media to obtain the best results. For example, aluminum needs to be polished with a softer media, while harder materials such as steel may need a harder media.
Once the necessary grit of the abrasive media have been used, it is necessary to apply a polishing compound. This compound is used to create a smooth, glossy finish. After polishing, the surface is then rinsed with water to remove any remaining debris.
It is important to remember that mechanical polishing can be time consuming and expensive. Although the results are typically worth the effort and money spent, it is important to ensure that the proper steps are taken to achieve the desired result. For example, using incorrect grits or polishing compound can damage the surface or reduce the life of the material. It is also important to determine which substrates will react positively or negatively to the process and make the necessary adjustments in order to obtain the best results.
Mechanical polishing is used in a variety of industries including automotive, aerospace, defense, and medical. It is a specialized process that requires the correct steps and materials in order to obtain the desired finish. When performed properly, it can create a beautiful and durable surface that will last for many years.
