Features:

  • Multiple color options
  • Stable surface performance
  • Maintains metallic appearance

High Gloss Finish

Recommended:

  • Polishing
  • Electroplating

Features:

  • High surface brightness
  • Excellent visual appearance

4. How Does Surface Treatment Affect CNC Accuracy?

For precision components, surface treatment affects not only appearance but also dimensional accuracy.

Therefore, manufacturing engineers must consider:

  • Surface treatment thickness
  • Critical dimensions
  • Assembly tolerances

For example:

For precision assembly components, machining dimensions should include proper allowance for surface treatment thickness.
