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 3004 Aluminum with CNC Laser Cutting
The machinability of 3004 Aluminum is excellent; high cutting speeds and superb finishes achievable. For CNC Laser Cutting we select tooling, feeds, speeds and coolant to match, keeping the 3004 Aluminum workpiece stable and the result accurate.
Because we machine 3004 Aluminum regularly, proven settings shorten setup and keep quality repeatable across reorders.
Achievable Tolerances for CNC Laser Cutting 3004 Aluminum
| Feature | Standard | Precision |
|---|---|---|
| Contour dimension | ±0.10 mm | ±0.05 mm |
| Hole diameter | ±0.10 mm | ±0.05 mm |
| Kerf width | 0.20 mm | 0.10 mm |
| Squareness of cut edge | 0.5° | 0.2° |
| Heat-affected zone | 0.15 mm | 0.05 mm (N₂ assist) |
| Minimum hole diameter | 1.2 × thickness | 1.0 × thickness |
| Edge condition | light dross | burr-free, N₂ cut |
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.
Design Tips for CNC Laser Cutting 3004 Aluminum
A few design choices make a real difference to cost and quality. Keeping holes no smaller than the material thickness, allowing for kerf, and grouping features sensibly improves edge quality and nesting yield on 3004 Aluminum. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Laser Cutting Tolerances & Surface Finish
Laser-cut 3004 Aluminum holds contour tolerances around ±0.05 mm depending on thickness, with a narrow kerf and a clean, near burr-free edge.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
Secondary Operations & Finishing
We complete 3004 Aluminum components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
CNC Laser Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 3004 Aluminum parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.

Finishing Options for 3004 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 Laser Cutting 3004 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 3004 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.
