When you order CNC machined parts online, selecting the correct geometric dimensions and tolerances is only half the battle. The final surface finish is a critical, often underestimated, factor that directly impacts your part's functionality, durability, and aesthetics. For businesses seeking reliable, onestop CNC machining solutions, understanding finish options is key to ensuring project success and driving growth through superior quality.

While costeffective and quick, it may show visible tool marks and have a higher surface roughness (typically around 125 µin Ra). This is suitable for noncritical internal components or functional prototypes. For parts requiring smoother operation, better sealing, or improved fatigue resistance, secondary finishing processes are essential.
A highly popular choice is Bead Blasting, which creates a uniform, matte, satinlike surface. It excellently conceals minor tool marks, provides a clean, professional appearance, and is ideal for handling surfaces or parts visible in the final assembly.
For applications demanding smooth motion, reduced friction, or enhanced corrosion resistance, Anodizing (Type II or Type III) is the industry standard. This electrochemical process hardens the surface and creates a porous layer that can be dyed in various colors for part identification or branding. It is particularly vital for aluminum components in aerospace, automotive, and consumer electronics.
When superior corrosion resistance, nonconductivity, or chemical inertness is required for plastics or metals, Powder Coating offers a thick, durable, and attractive colored layer. For metal parts needing ultimate hardness and wear resistance, Hard Chrome Plating or Nickel Plating are preferred solutions.
