Finishes and Coatings for CNC Machined Parts

Compare practical surface finishes and advanced coatings that can improve wear, appearance, and corrosion resistance.

Standard Finishes

Compare three standard options for the appearance and edge condition of CNC machined components.

Deburred

A practical baseline that removes common machining burrs while retaining the natural material appearance.
