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.
How CNC Saw Cutting Aluminum Works
The Aluminum blank is bent or formed against tooling under CNC-controlled ram travel and back-gauge positioning. Bend allowance and springback are compensated in the program so finished angles hit the print.
Every job begins from your CAD model or 2D drawing. Fixturing and tool paths are planned so the most critical dimensions are produced in the most rigid, repeatable setup. Critical dimensions are checked on the first part and monitored through the run.
Achievable Tolerances for CNC Saw Cutting Aluminum
| Feature | Standard | Precision |
|---|---|---|
| Bend angle | ±1.0° | ±0.5° |
| Flange length | ±0.30 mm | ±0.15 mm |
| Hole-to-bend distance | ±0.30 mm | ±0.15 mm |
| Minimum inside radius | 1.0 × thickness | 0.8 × thickness |
| Minimum flange height | 4 × thickness + radius | 3 × thickness + radius |
| Bend-to-bend spacing | ±0.30 mm | ±0.15 mm |
| Sheet thickness range | 0.5–8.0 mm | 0.5–4.0 mm |
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
We complete 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 Saw Cutting Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 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.
Working with Aluminum
Aluminum offers a useful combination of properties: it is lightweight, excellent machinability, good corrosion resistance. Those characteristics shape how we approach forming — from tool and parameter selection to work-holding and coolant.
If your application is sensitive to alloy condition, we agree the specification in writing and document it. Stock is sourced from reputable suppliers so what you order is what you receive.
Design Tips for CNC Saw Cutting Aluminum
A few design choices make a real difference to cost and quality. Consistent bend radii, adequate flange lengths and grain-direction awareness reduce cracking and springback in formed Aluminum. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Saw Cutting Tolerances & Surface Finish
Formed Aluminum holds bend angles to about ±0.5° and consistent flange dimensions, with bend allowance compensated for the material and thickness.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Applications of CNC Saw Cutting Aluminum
CNC Saw Cutting of Aluminum supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.
How to Order CNC Saw Cutting Aluminum
Ordering Aluminum parts is straightforward. Provide the drawing, material, quantity and any certification needs. Our engineers reply — in English — with feasibility, pricing and a realistic lead time, usually within one business day.
Parts We Have Run in Aluminum
Three representative CNC Saw Cutting Aluminum jobs, with the callouts that actually drove the process plan. Yours will differ — these are here so you can judge whether your part is in our range before you spend time on an RFQ.
Radiused cover
- Material
- Aluminum
- Size
- R150 × 500 mm
- Key callouts
- Radius ±1 mm, no tool marks
- Batch
- 200 pcs
Bumped in 14 small steps rather than rolled, because the batch does not justify a roll set.
Mounting bracket

- Aluminum
- Size
- 120 × 60 mm, 2 bends
- Key callouts
- Angle ±0.5°, hole-to-bend ±0.15 mm
- Batch
- 3,000 pcs
Holes placed at least 2.5 × thickness from the bend line so they do not distort.
Sheet-metal enclosure
- Material
- Aluminum
- Size
- 300 × 200 × 120 mm
- Key callouts
- Bend angle ±0.5°, diagonal ±0.5 mm
- Batch
- 400 pcs
Bend sequence chosen so no flange collides with the tool on the last hit.
Finishing Options for 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 Saw Cutting 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 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.

Request a QuoteFrequently Asked Questions
Can VT machining make custom Aluminum parts to my drawing?
Yes. Aluminum Aluminum forming is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What tolerances can you hold for CNC Saw Cutting Aluminum?
Achievable tolerances for Aluminum forming depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
What is the typical lead time and minimum order for CNC Saw Cutting Aluminum?

What is CNC Saw Cutting Aluminum and how is it done?
CNC Saw Cutting Aluminum refers to cNC saw cutting sections bar, tube and plate to precise length for downstream machining. Applied to Aluminum — lightweight, excellent machinability, good corrosion resistance — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Does CNC Saw Cutting Aluminum require dedicated tooling?
Most Aluminum forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
