MATCH THE PROCESS TO THE PART
Custom aluminum milling and turning
Housings, brackets & plates
CNC milling for pockets, slots, bores, mounting holes and machined faces. Identify critical mating features and cosmetic surfaces so we can review the setup and finishing scope.
Shafts, bushings & sleeves
CNC turning for cylindrical features, shoulders, grooves and threads. Include any secondary flats, cross holes and relationships between features in the drawing.
Prototypes & small batches
Support for development parts and small production runs. Share the intended quantity and revision; a prototype approval and a repeat order may have different inspection or documentation needs.
6061 and 7075 aluminum machining
| Material option | What to send | Review before ordering |
|---|---|---|
| 6061 aluminum | Alloy, temper, material standard and drawing | Functional fits, cosmetic faces, surface treatment and any certification needs |
| 7075 aluminum | Exact condition and approved material requirements | Strength requirements, service environment, finishing and permitted substitutions |
| Alternative aluminum grade | The proposed grade and reason for the change | Availability and suitability are confirmed during project review |
Not sure which alloy to specify? Read our 6061 vs 7075 aluminum guide. Material properties depend on the specified condition; we do not identify or certify an alloy from a photograph.
ALUMINUM MACHINING CASE STUDY
7075 Aluminum Five-Axis Machining
7075 aluminum components with curved profiles, circular openings and mounting features, produced using simultaneous five-axis CNC machining.
Surface condition: As-machined; no additional surface treatment.
View Machining Case →Surface finish and dimensional review
As-machined and black anodized aluminum parts can be reviewed against your requirements. State the required coating specification, visible surfaces, masking locations and whether critical dimensions apply before or after finishing. Review our CNC machining materials and surface finishes guide; other finishes require confirmation with the quotation.
Mark functional tolerances rather than applying an unspecified “high precision” requirement to the whole part. Our CNC machining tolerances and inspection guide and quality and inspection page explain the information to provide for important bores, hole patterns and mating faces.
CHECK YOUR PART BEFORE REQUESTING A QUOTE
Which aluminum machining route fits your part?
| Part features | Route to discuss | Details we need |
|---|---|---|
| Housings and brackets | Milling for pockets, mounting faces and hole patterns | Datums, mating faces, wall thickness and thread callouts |
| Shafts and bushings | Turning for bores, diameters, shoulders and grooves | Fits, runout requirements, bore depth and any cross holes |
| Curved or multi-sided parts | Review tool access, workholding and the need for multi-axis machining | A 3D model plus a drawing that marks critical features |
For example, our 7075 five-axis machining case shows curved parts in their as-machined condition. It does not define a standard tolerance or maximum size for every new project.
Machine travel and usable part size
Our JF-V1200 three-axis machining center has X/Y/Z travel of 1200 × 600 × 600 mm. However, fixture space and tool clearance also affect usable part size. Send the full geometry for review before selecting a machining route.
For repeat orders, use our small-batch machining service to discuss prototype approval, drawing revisions and follow-on quantities.
Prepare a complete aluminum machining RFQ
- Define the part: send the current model and PDF drawing with matching part number, units and revision.
- Define the order: include alloy and temper, quantity, finish, required date and delivery destination.
- Define acceptance: identify critical fits, inspection documentation, certification and packaging needs.
See the CNC quotation drawing checklist for a practical way to organize your inquiry.
Aluminum machining questions
Can you quote a prototype and a later production batch?
Yes. List the quantities separately so we can review the setup, inspection and delivery scope for each stage. Pricing and lead time are confirmed in the quotation.
Can the part be anodized after machining?
Include the requested anodizing and masking requirements at the quotation stage. Finish suitability and dimensional allowances need review before machining.
What information determines the quotation?
Geometry, material condition, quantity, tolerances, surface finish, inspection and delivery requirements all form part of the review. Send those details rather than relying on a similar product photo.
