Our As Machined Services
We focus on As Machined with General surface treatment with an Ra 3.2μm (126μin) roughness specification, ensuring edge radiusing and complete burr removal.
As Machined Services Overview
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.

Cleaning, deburring, and breaking sharp edges only after machining presents a surface without further refinement.
As Machined Advantages
- Faster production time because it does not require extra finishing steps.
- It preserves the workpiece’s integrity and retains its natural look.
- Extensive machining material supports.
- Suitability for parts with strict dimensional tolerances.
- Cost-effectiveness because the surface finish does not require additional processing.
Notes
- A finishing cutting pass can be applied to reduce the roughness of a surface down to 0.8 or 0.4 μm.
As Machined Applications
- Simplify the Part Geometry: Avoid complex part design and reduce tight tolerance when feasible to facilitate a smoother machining operation and reduce surface imperfections.
- Optimize Tooling and Toolpaths: Use sharp and high-quality tools and carefully planned tool paths to minimize vibrations and enhance cutting efficiency, which can affect the surface finish.
- Select Machinable Materials: Use CNC machining materials with excellent machinability and favorable surface finish properties.
