Assess your aluminum part for milling, turning or five-axis work. Confirm alloy, temper, stock constraints, critical geometry and finish so the machining and inspection route fits the drawing.
Jaquent reviews aluminum enclosures, brackets, plates, flanges and other drawing-defined parts. Pockets and faces commonly lead to milling; rotational features to turning; complex access can need a five-axis review.
Specify alloy and temper together. 6061-T6, 7075 and 7050 are distinct specifications, and material condition or stock form can change movement during machining and finishing response. Other alloys or tempers are confirmed through stock and project review. No listed material implies immediate inventory.
Identify cosmetic faces, fits, thin regions and final flatness or datum relationships. If a finish is required, agree the process, masking, appearance reference and final accepted dimensions before machining. For a broader material decision, use the CNC material selection guide.
A commonly reviewed specification for enclosures, brackets and plates. Confirm stock, cosmetic requirements, finishing and the final fit state for the actual part.
Specify the exact alloy and temper rather than treating these grades as interchangeable. Review residual stress, stock form, thin sections and the required finish.
| Specified material | Project inputs | Machining questions | Acceptance input | Finish to confirm |
|---|---|---|---|---|
| 6061-T6 | Drawing, material specification, stock constraints and quantity | Pocket/wall stiffness, clamping and cosmetic-face protection | Critical dimensions, datums and the final condition of fits | Anodizing or other specified finish, masking and appearance reference |
| 7075 or 7050 with specified temper | Exact alloy, temper and stock condition; alternatives require agreement | Residual stress, rough-to-finish sequence and movement on release | Required form, location and size after all specified operations | Compatibility, masking and appearance accepted for the selected grade |
Ductile aluminum can build up on a cutting edge and affect the surface. Tool geometry, chip evacuation and coolant strategy need review for the alloy and feature; identify faces where the resulting finish is functional or cosmetic.
Mark cosmetic faces and any surfaces that may be used for clamping. Workholding contact, handling and later finishing must be considered together so the appearance requirement can be quoted clearly.
Thin walls and large flats can move with cutting heat, clamping and stress release. Identify their free-state size and form requirements so support, roughing and final inspection can be planned together.
Residual stress can be released as material is removed from 7075 or 7050 stock. Confirm alloy, temper and stock form, then review rough-to-finish staging and the final geometry after unclamping.
The machining image and representative housings and flanges provide context for access, clamping and chip control. They do not establish alloy grade or dimensional acceptance. For a documented example, see the original aluminum knurl case on the turning page, which describes visual appearance control with its stated scope.
Material condition, residual stress, thin walls and unclamping can affect aluminum dimensions. Identify critical interfaces and whether their acceptance is before or after finishing.
Apply individually specified requirements and any general drawing tolerance to their stated scope and edition. Where neither applies, ±0.10 mm is a common quotation basis. Selected milling or turning features may be reviewed to ±0.01 mm. For a five-axis route, designated critical features may be reviewed to ±0.005 mm where material and geometry allow, confirmed through DFM. Swiss-turned linear features and critical wire EDM features have their own process-specific references; confirm the applicable service and feature rather than transferring one figure to every operation.
Pre-shipment inspection at the authorized manufacturing facility follows the drawing and agreed plan. Every-part checks apply to named features when specified; other checks can follow agreed sampling. Request material records, traceability, dimensional reports, customer FAI forms or a CoC in the quotation, with coverage and format confirmed. See functional tolerances and GD&T and inspection scope and required records.
Type II and Type III anodizing, blasting, deburring or polishing, and conversion coatings are available or coordinated per project. Specify coating type, color, masking, and dimensional build-up on critical fits. Hardware inserts and light assembly can be included in the same order when specified. Details: CNC surface finishes.
Define visible faces and an agreed appearance reference separately from dimensional limits. Identify bores, threads, sealing faces and electrical contact areas that need masking or checks in the final finish state. A color name alone leaves texture, sheen and permitted rack or contact marks open.
