Aunov Tech builds this Aluminum and Steel CNC Turned Caps and Fittings in aluminum or steel, from coil or bar through to the finished surfaces. In duty, the CNC machined part carries the controlled features that forming alone cannot hold. Forming and machining share equipment, staff and batch records, so first-article dimensions hold through volume batches with no third party in the loop.
Product overview
The drawing for this aluminium fitting fixes, draw depth, wall band and the surfaces that forming cannot hold, re-checked whenever the drawing is revised.
Toolroom, presses and machining centres used on this aluminium fitting operate on the same site, so a drawing change is absorbed in one step, and the same die can be re-cut from the original data.
Production route
Production follows a defined route: Bar and plate are cut on CNC turning and milling centres; threads are single-pointed or rolled and seats bored in one setup where possible.
Repeat turned cross fitting orders are measured against the approved sample, so neither material nor finish drifts between lots. The approved turned cross fitting sample governs later runs, and any grade change is agreed in writing first.
Materials and finishing
Base materials in stock: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and the grade agreed for this aluminium fitting is aluminium.
Finish selection follows the working environment: polishing, zinc / nickel / chrome plating, anodising or powder coating. It is written into the drawing for this aluminium fitting, so it cannot drift between batches.
The turned cross fitting tooling and setup record is stored against the part number, so nothing depends on someone remembering. Mill certificates are filed per heat, so turned cross fitting traceability survives a change of material batch.
Quality control
The plant is ISO 9001 certified: material traceability starts with mill certificates, first-article geometry is confirmed on the CMM, and routine sampling keeps batches aligned with the first article. For the turned cross fitting, first articles are CMM measured and threads are gauged to class. Torque, leak and pressure tests are available where the assembly needs them, and the report is packed with the shipment.
Applications
This aluminium fitting is used in industrial machinery and equipment assemblies in volume programmes as well as aftermarket supply.
Drawings for this aluminium fitting are adapted across programmes, so one tooling set serves every position, and the same first article applies throughout.
Customization and options
Options changed most often
What customers usually vary on this aluminium fitting: wall thickness bands, flange geometry, thread call-outs and the surface finish, and how the order is released – sample, pilot run or scheduled call-off.
Quotes for this aluminium fitting show which options the current die already supports, so you can see which options are free and which need new tooling. The agreed validity period governs how long the turned cross fitting price stands.
Specifications
| Item | Aluminum and Steel CNC Turned Caps and Fittings |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – samples are reverse-measured into a controlled drawing; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | Samples are issued for approval before the run, so any deviation is corrected at sample stage, and later batches are gauged back to the signed sample. |
| Materials | Stock runs to carbon steel, 304 / 316 stainless, aluminium and brass; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; finish thickness and adhesion checked on the first article. |
| Processing | Turning, milling and drilling sequenced to minimise handling and re-chucking; batch records are filed so a repeat order starts from approved data. |
| Equipment | Turning centres fed from bar, with machining centres for milled features, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.02 mm general machining, tighter on flagged dimensions; dimensional reports accompany the first article. |
| Delivery terms | FOB Ningbo or Shanghai, T/T with deposit and L/C for larger runs; each volume tier carries its own quoted price. |
Packaging and delivery
For this aluminium fitting, protection starts at the surface: interleaves, bags or trays are matched to the surface treatment, in sealed cartons on export pallets, documented and marked to your instruction.
