Published typical values for 6061-T6. Other grades in the family differ — the certificate supplied with your order carries the actual heat-lot figures.
Thin walls relax after roughing. We rough, let the part stabilise, then finish — otherwise a 1.5 mm wall bows by more than the tolerance it was cut to.
Machining 5086 Aluminum with CNC Polishing
When finishing 5086 Aluminum, machinability is excellent; high cutting speeds and superb finishes achievable. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for 5086 Aluminum mean predictable cycle times and stable, repeatable results.
Achievable Tolerances for CNC Polishing 5086 Aluminum
| Feature | Standard | Precision |
|---|---|---|
| Surface roughness | Ra 0.8 µm | Ra 0.05 µm |
| Edge break | 0.1–0.3 mm | 0.05 ±0.02 mm |
| Material removed | 0.02 mm | 0.005 mm |
| Bore roundness after honing | 0.005 mm | 0.002 mm |
| Cross-hatch angle | 45° ±10° | 45° ±5° |
| Cosmetic grade | uniform satin | mirror, no visible lines |
| Masking of datum faces | on request | standard |
Standard is what a normal quotation assumes. Precision is available on nominated features and is priced separately, because it needs extra setups, in-process gauging and CMM verification. Call out only the features that need it — blanket-tightening a drawing is the single most common reason a quote comes back expensive.
Secondary Operations & Finishing
Most 5086 Aluminum parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
Why 5086 Aluminum?
Customers select 5086 Aluminum for CNC Polishing because it is lightweight with excellent machinability. We handle grade verification and any required heat treatment or finishing.
CNC Polishing Tolerances & Surface Finish
Finishing brings 5086 Aluminum to a defined roughness target — from a uniform satin to Ra values as low as 0.05 µm — with controlled, repeatable edge breaks.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Design Tips for CNC Polishing 5086 Aluminum
Small design adjustments often cut cost and lead time. Telling us the target Ra, the cosmetic faces and any masking needs lets us finish 5086 Aluminum efficiently without over-processing. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Polishing Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
Applications of CNC Polishing 5086 Aluminum
5086 Aluminum parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Polishing 5086 Aluminum
Starting your project takes one email. Send your CAD or 2D drawing, the 5086 Aluminum grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.
Finishing Options for 5086 Aluminum
| Finish | Thickness / effect | Why it gets specified |
|---|---|---|
| Clear anodise (Type II) | 5–25 µm | Corrosion protection, keeps the natural colour |
| Colour anodise | 10–25 µm | Black, red, blue, gold; add 0.02 mm to close tolerances |
| Hard anodise (Type III) | 25–50 µm | 60–70 HRC surface, grows 50% into the part |
| Chromate / Alodine 1200 | < 1 µm | Conductive, meets MIL-DTL-5541 |
| Powder coat | 60–120 µm | RAL colours, needs 0.3 mm clearance on mating features |
| Deburr / edge break | 0.05–0.3 mm | All parts unless the drawing says otherwise |
| Bead blast | Ra 1.6–3.2 µm | Uniform matt finish, hides tool marks |
| Laser marking | — | Part number, lot code, data matrix |

What We Need to Quote CNC Polishing 5086 Aluminum
- GeometrySTEP or IGES for the 3D model, plus a PDF drawing if you have tolerance callouts. A dimensioned sketch is enough to start.
- MaterialThe exact 5086 Aluminum grade and condition — temper, heat-treat state or hardness. If you are not sure, tell us the function and we will suggest one.
- QuantityPrototype count and the expected annual volume. Both change how the part is made and therefore what it costs.
- TolerancesWhich features are critical. Everything else runs to our standard tolerance, which is what keeps the price sensible.
- FinishSurface treatment, cosmetic requirements, and any faces that must be masked.
- DocumentsWhether you need a material certificate, dimensional report, FAIR or PPAP with the shipment.
Missing something from the list is not a problem — send what you have. We will come back with the specific questions rather than a generic form.
