Mirror polishing is usually done with a polishing machine, polishing paste, polishing ball, etc.
The process by applying a polishing compound to the part and achieve to a high gloss.
Mirror polishing is much smoother and more durable than conventional polishing processes.
Available Materials For Mirror Polishing
Aluminum
High machinability and ductility, good strength-to-weight ratio. Aluminum alloys have good strength-to-weight ratio, high thermal and electrical conductivity, low density and natural corrosion resistance.
Iron
Iron is an indispensable metal in the industrial sector. Iron is alloyed with a small amount of carbon – steel, which is not easily demagnetized after magnetization and is an excellent hard magnetic material, as well as an important industrial material, and is also used as the main raw material for artificial magnetism.
Steel
Steel is a strong, versatile, and durable alloy of iron and carbon. Its applications range from construction materials and structural components to automotive and aerospace components.
Steel is strong and durable High tensile strength Corrosion resistance Heat and fire resistance Easily molded and formed.
Stainless steel
Stainless steel alloys have high strength, ductility, wear and corrosion resistance. They can be easily welded, machined and polished. The hardness and the cost of stainless steel is higher than that of aluminum alloy.
Bronze
Highly resistant to seawater corrosion. The material’s mechanical properties are inferior to many other machinable metals, making it best for low-stress components produced by CNC machining.
Brass
Brass is mechanically stronger and lower-friction metal properties make CNC machining brass ideal for mechanical applications that also require corrosion resistance such as those encountered in the marine industry.
Copper
Few metals have the electric conductivity that copper has when it comes to CNC milling materials. The material’s high corrosion resistance aids in preventing rust, and its thermal conductivity features facilitate CNC machining shaping.
Design Considerations
- Substrate preparation: Proper substrate preparation is essential to ensure the desired surface finish is achieved.
- Tooling selection: Mirror polishing requires the use of specific tools and compounds.
- Material properties: Different materials have different properties and require different polishing techniques.
- Surface finish: When selecting polishing tools, such as polishing compounds, etc., the desired surface effect should be considered.
