Surface finish is not just cosmetic—it directly impacts performance, durability, corrosion resistance, and compliance. In CNC machining, surface roughness (Ra) can determine whether a part succeeds or fails in real-world applications.
At FIESCO, surface finish is controlled through machining precision and finishing services.

What Is Surface Finish (Ra)?
Surface roughness (Ra) measures the average height variation of a machined surface. Lower Ra values mean smoother surfaces.
- Ra 3.2–6.3 µm → Rough industrial parts
- Ra 1.6–3.2 µm → General machining
- Ra <1.6 µm → Precision and hygienic applications
Why Surface Finish Is Critical
Mechanical & Automotive
Reduces friction, wear, and fatigue.
Food Industry
Smooth surfaces prevent bacterial growth and ensure hygiene.
Medical Industry
Essential for biocompatibility and sterilization.
Construction Equipment
Improves durability and corrosion resistance.
