What Is CNC Milling Service & How CNC Milling Works

CNC milling is a subtractive manufacturing process that rapidly removes material from metal or plastic blocks to produce precision parts with tight tolerances.

CNC Milling is best suited as a secondary or finishing process for an already machined workpiece, providing definition to or producing the part's features, such as holes, slots, and threads. However, the process is also used to shape a stock piece of material from start to finish. In both cases, the milling process gradually removes material to form the desired shape and form of the part. First, the tool cuts small pieces—i.e., chips—off the workpiece to form the approximate shape and form. Then, the workpiece undergoes the milling process at much higher accuracy and with greater precision to finish the part with its exact features and specifications. Typically, a completed part requires several machining passes to achieve the desired precision and tolerances. For more geometrically complex parts, multiple machine setups may be required to complete the fabrication process.

Ouzhan CNC Milling Surface Finishes
Here is a wide selection of metal surface finishing services at your choice for the machined CNC milling parts to improve the parts appearance, surface smoothness, corrosion resistance, and other characteristics:

CNC Milling Surface Finishes
CNC Milling Surface Finishes1

① As machined(standard): ~125 RA µin (3.2 RA µm). Minor tool marks will be visible on the part.
② Smoothed: Parts are machined at a lower feed rate in order to achieve a surface roughness of ~62.5 RA µin (1.6 RA µm). Surface roughness can be decreased up to ~32 RA µin (0.8RAµm) upon request.
③ Bead Blasted: Bead blasting adds a uniform matte or satin surface finish on a machined part, removing all tool marks. Mainly used for aesthetic purposes.
④ Anodized Clear or Color: Anodizing adds a thin, hard, non-conductive ceramic coating on the surface of aluminum parts, increasing their corrosion and wear resistance. Available in a variety of colors.
⑤ Anodized Hardcoat: Hardcoat anodizing produces a thicker ceramic coating providing excellent corrosion and wear resistance. for functional applications.
⑥ Powder Coated: Powder coating adds a thin layer of strong, wear and corrosion resistant protective polymer paint on the surface of a part. Available in a large range of colors.
⑦ Electropolished: Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface surface roughness.
⑧ Black oxide: Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.
⑨ Chromate conversion coating (Alodine/Chemfilm): Chromate conversion coating is used to increase the corrosion resistance of metal alloys while maintaining their conductive properties.
⑩ Brushing: Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish.
