Our quality-focused As Machined services produce parts with surface finish having a surface roughness of Ra 3.2μm and Ra 1.6μm without additional finishing.
Parts with as-machined surface finish are characterized by visible tool markings with a surface roughness depending on the machine tool, cutting parameters, tool paths, and the operator’s expertise.
This surface finish is what you get after freshly machining a part without subjecting it to additional processing like honing, grinding, and other surface finishing treatments.
As machined services deliver a machined surface finish, the most convenient option for parts needing tight tolerance and reduced manufacturing cost.
