As Machined Surface Finish Supplier In China
At Celerity Precision, surface finishing is an integral part of our in-house manufacturing process. We offer a comprehensive suite of finishing capabilities, managed under one roof to ensure strict quality control, full process traceability, and optimal results for your components’ performance and longevity.
Your As Machined Surface Finish Manufacturer
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.
| Surface Roughness | Applicable Materials | Cosmetic Availability | Visual Appearance |
|---|---|---|---|
| Ra 3.2μm | Metals, Plastics | No | Cleaning, deburring, and breaking sharp edges only after machining presents a surface without further refinement. |
| Ra 1.6μm | Metals, Plastics | No | Cleaning, deburring, and breaking sharp edges only after machining smoother than Ra3.2 through better machining controls. |
Advantages of As Machined Surface Finish
- 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
As Machined Design Considerations
- 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.
FAQ
What constitutes a typical surface finish in machining?
The constitution of typical surface finish in machining are roughness, waviness, and lay. Roughness is the irregularities of a part’s surface measured by parameters like roughness average and affected by the machining tool, material, cutting speed, and feed rate.
Waviness is more prolonged irregularities on a part’s surface caused by machine or workpiece deflections, vibrations, or other external factors during machining. Lastly, Lay is the direction of the surface pattern, and it depends on the machining process.
