Surface Finishes Services in China | CNCFIRST
Product Details: CNCFIRST offers a range of surface finishes for CNC machined parts. The standard surface finish is ‘as machined,’ which removes sharp edges and burrs, with a surface roughness of 3.2 μm. Other finishes include anodizing, which enhances performance, appearance, and durability by creating a protective oxide film; black oxide, which adds a matte black finish and protects against corrosion; and polishing, which enhances the natural beauty of the material. Additional finishes include bead blasting, brushing, electroless nickel plating, and powder coating. Bead blasting smooths and rounds out rough edges, while brushing ensures cleanliness and accuracy. Electroless nickel plating adds a
protective layer of metal, and powder coating provides a durable finish resistant to harsh conditions[3].
