AA/CAP/003Capability
Welded fabrication
AA/CAP/003 · ENVELOPE 3000 × 1500 × 1500 MM · ISO 2768-F · ISO 9001 IN PROGRESS · 24 H VERIFIED QUOTE
Tube frames, test stands, MGSE and handling fixtures welded to a qualified procedure, stress relieved and machined at the interfaces, with dye-penetrant inspection on structural welds.
Envelope and tolerances
What we commit to as standard
Beyond an envelope we route to manual review; we do not decline. Tolerance classes are per ISO 2768 unless a feature is called tighter on the drawing.
| Item | Standard envelope (mm) | Baseline lead time |
|---|---|---|
Welded fabrication Prototype quantity, before material and finish factors | 3000 × 1500 × 1500 | 18 working days |
| Item | Value | Governing standard / note |
|---|---|---|
General tolerance | ISO 2768-m | ISO 2768-1 medium class; default when the drawing is silent |
Fine tolerance | ISO 2768-f | ISO 2768-1 fine class; recommended for structural hardware |
Precision features | ±0.05 mm | Called per feature; verified on CMM |
Precision features, hard alloys | ±0.025 mm | Grinding or hard-turning pass and CMM verification; a cost step, not a blocker |
Minimum wall, committed | 0.8 mm | Below this the line is held for review |
Thin-wall review threshold | 1.2 mm | Between the floor and this, a stress-relief step or accepted flatness deviation |
Surface finish, as-machined | (125 Ra) | Finer on request; see finishes |
Materials
Alloys we source, by family
Certified stock with mill test certificates traced to heat and lot. The relative cycle-time factor drives our lead-time model; it is not a price factor.
| Item | Density | Cycle-time factor | Anodising route |
|---|---|---|---|
Aluminium 6061-T6 | 2.70 g/cm³ | ×1.00 | MIL-A-8625 |
| Item | Density | Cycle-time factor | Anodising route |
|---|---|---|---|
Stainless 316L | 8.00 g/cm³ | ×1.80 | Not anodisable |
Stainless 17-4 PH | 7.80 g/cm³ | ×2.00 | Not anodisable |
Need an alloy not listed? Add it as a note on the RFQ line. It is routed for manual review with a sourcing check before we quote. We do not decline on the alloy alone.
Finishes
Every finish names its specification
A finish call-out without a specification is not one we accept on a drawing or publish here. Where a treatment has no governing standard, the parameters are agreed in writing per job.
| Item | Governing specification | Added lead time | Applies to |
|---|---|---|---|
As-machined (125 Ra) | None (baseline, no treatment) | No added time | Aluminium, Corrosion-resistant steel |
Bead blast | Media and pressure recorded per job | +1 working days | Aluminium, Corrosion-resistant steel |
Passivation | ASTM A967 / AMS 2700 | +2 working days | Corrosion-resistant steel |
Electroless nickel | MIL-C-26074 | +4 working days | Aluminium, Corrosion-resistant steel |
Inspection
Inspection levels
Chosen per line on the RFQ. Where a vendor or an accredited lab took the measurement, our report says reviewed by or witnessed by, never inspected by.
| Item | Added lead time | Included |
|---|---|---|
Standard dimensional | No added time | On every line |
First Article (AS9102) | +1 working days | On request |
Full CMM report | +2 working days | On request |
CMM + NDT (DPI/UT) | +3 working days | On request |
