As Machined Service
As Machined Service
An as-machined surface finish features visible tool marks, with surface roughness influenced by the machine tool, cutting parameters, tool paths, and operator expertise.
This finish is the result of machining without additional post-processing, such as honing or grinding.
As-machined surfaces are an ideal choice for parts requiring tight tolerances and cost-effective manufacturing

Visual Appearance |
|---|---|---|---|
| Ra 3.2μm | Metals, Plastics | No | Cleaning, deburring, and breaking sharp edges after machining result in a surface with no additional refinement |
| Ra 1.6μm | Metals, Plastics | No | With improved machining controls, this process can achieve a smoother finish, typically better than Ra3.2. |
As-Machined Design guide:
Simplify Part Geometry: Minimize complex designs and relax tight tolerances when possible to improve machining efficiency and reduce surface imperfections.
Optimize Tooling and Toolpaths: Use sharp, high-quality tools and well-planned toolpaths to reduce vibrations and improve cutting efficiency, enhancing surface finish.
Select Machinable Materials: Choose materials with good machinability and favorable surface finish properties for optimal results
