Stainless Steel Casting With Mirror Polishing
Posted by Admin
Stainless steel casting parts can be polished to give them a mirror finish. While there are many different polishing methods that can be used, the process is relatively simple. The main goal is to get the metal to shine naturally. This process can be done on vehicles, sculptures, garden ornaments, and more.
A mirror polished stainless steel casting part has a high shine and a polished finish. Stainless steel castings can be polished in three different steps: sanding, fine grinding, and buffing. The sanding and fine grinding stage is important to prepare the surface for polishing. This process removes deep scratches and irregular shapes. It is also necessary to remove the oxide film that can inhibit uniform polishing of products. Stainless steel castings may also be chemically stripped to remove the oils and grease that may accumulate on their surface.
After the rough polishing stage, the metal should be buffed with a buffing wheel or compound. Depending on the type of metal that is being polished, different types of buffing wheels and compounds will be needed. While buffing, the last few strokes should be downward. This will help to remove any light haze that may have accumulated on the surface. If necessary, a microfiber towel can be used to wipe the surface down.
Polishing aluminum casting parts requires different types of buffing wheels and compounds. When buffing, it is important to start with the coarsest abrasive. This is usually a 40-grit sanding disc mounted on a power drill. Smaller aluminum pieces can be sanded by hand. To increase the speed of the sanding process, you may want to invest in an orbital sander with PSA discs. If you are looking to get a high finish, you can use an air-powered die grinder with a conical sanding attachment.
If you want to polish aluminum casting parts to give them a mirror finish, start by using a brown tripoli aluminum abrasive compound. This compound removes abrasion marks and deep scratches, making the surface shine like a mirror. However, this compound will not remove all imperfections. If you notice small black spots on your surface, you will need to add more compound to the buffing wheel.
To finish the process, you may want to use a green rouge compound bar or another buffing compound. These compounds should be used with a clean microfiber towel to wipe the surface down. Once the buffing process is complete, you should clean the abrasive residue off with InoxiClean Chalk. It is also a good idea to rake out the wheel to remove the compound you used for the color buffing process.
Mirror polished cast stainless steel parts are popular with customers. Customers love the shine and corrosion-resistant quality of these parts. They are also useful in architectural and marine applications. While there are different ways to achieve the mirror finish, the most popular method is mechanical mirror polishing. Mechanical mirror polishing involves grinding, polishing, and buffing the metal to produce a shiny, smooth finish.
