    Available Surface Finishes After CNC Turning Services
    Surface finishes are applied after turning and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts. Below are the mainstream surface finish types from WELDO:
    As Machined

    This is the standard choice, economical and rapid, the parts’ surface will leave visible machining marks. The surface finish is equivalent to 3.2RA μm (125 RA μin).


    Polishing is to make the surface smooth by physical friction processing, it is often used to prevent corrosion and remove oxidation. After polishing, the parts have a smoother and brighter finish.

    Bead Blasted

    Bead blasting is the process of spraying abrasive on the surface of parts under high pressure, after sandblasting, the metal parts have a satin texture or frosted surface, eliminating the processing marks.


    After anodizing, a hard non-conductive ceramic coating will be added on the surface of aluminum parts to improve the wear resistance and retain the metal texture and luster.


    Electropolishing is the reverse process of electroplating, which simplifies the metal surface at the micro-level through chemical solution. After electropolishing, metal parts can be more bright and reduce surface roughness.

    Black Oxide

    The black oxide is a chemical conversion coating, it is produced by a chemical reaction between iron and oxide salt in black oxide solution. The corrosion resistance of parts can be improved after black oxidation.

    Powder Coated

    Powder coating can add a layer of solid and colorful polymer coating on the surface of parts, so as to improve the wear resistance and corrosion resistance.

    Spray Painting

    Spray painting is to spray paint on the surface of parts in the air. After painting, the parts have various colors, improve the aesthetic appearance, and make the parts unique, enhance brand awareness.
