Explore essential CNC machining surface roughness standards, from the 3.2 µm Ra commercial finish to finer grades for precision parts. Learn to select the right Ra value.

Chromate conversion is a kind of chemical conversion coating. When we put metal parts into the acidic chemical solution(contains chromate), the metal surface will form a thin coating. This coating does not react with most things, thereby it can improving corrosion resistance of substrate and enhancing coating adhesion.

Why Surface Roughness Matters

Surface roughness quantifies microscopic peaks and valleys on machined parts. It directly impacts:

• Functional Performance: Friction, wear, sealing, lubrication retention

• Aesthetics: Visual appearance and light reflection

• Manufacturing Cost: Finer finishes require additional operations (grinding, polishing)
