Surface Treatment for CNC Milled Parts

Surface treatment for CNC machined parts enhances durability, performance, and aesthetics by modifying the material’s surface. Standard techniques include anodizing, plating, coating, polishing, and shot peening. These treatments improve corrosion resistance, wear resistance, and surface hardness. For example, anodizing aluminum increases its resistance to corrosion, while shot peening improves fatigue resistance. Surface treatments are crucial for industries like aerospace, automotive, and medical devices, where component longevity and reliability are critical under harsh operational conditions.
