The Stainless Steel CNC Turned Shaft and Fittings is produced by Aunov Tech from stainless steel, formed and finished under one roof. In service, the CNC machined part provides the finished surfaces, threads and seats the mating parts locate on. Forming, machining and inspection share one floor, so first-article dimensions hold through volume batches on one production route.
Product overview
The specification of this stainless steel fitting turns on, the draw ratio, corner radii and the faces that must stay flat, recorded on the inspection report for every batch.
Tooling and finishing for this stainless steel fitting run under one roof, which keeps revision loops short and samples fast, and nothing about the route depends on a third party.
How it is manufactured
Manufacturing runs on a controlled process path: Bar stock is sawn and then machined on CNC turning and milling centres; tight features are held in one setup so concentricity does not depend on re-chucking.
Production batches of the flange ring are gauged back to the signed first article, not to a memory of it. Process settings for the flange ring are archived, so later runs can be compared with the one you approved.
Materials and surface finish
The standard stock list carries cold-rolled steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass, copper and bronze with this stainless steel fitting costed in 304 / 316 stainless steel.
The finish is chosen for the duty it will see: plating, anodising, powder coating, electrophoresis and passivation. It is written into the drawing for this stainless steel fitting, so it cannot drift between batches.
The flange ring manufacturing record is archived together with the drawing revision that produced it. Any change to the flange ring drawing is re-approved and re-verified before production continues.
Quality control
Production runs under an ISO 9001 certified quality system: incoming material is verified against mill certificates, the first article is CMM-measured against the print, and production batches are inspected on a sampling plan. First article of the flange ring: CMM data on diameters, thread class confirmed by gauge. Tests for torque, leakage or pressure can be arranged when the service demands them, with certificates included in the shipment file.
Applications
The stainless steel fitting is fitted into industrial equipment and general assembly work for customers who own the drawing and the tooling.
Drawings for this stainless steel fitting are adapted across programmes, so one approved version covers the whole range, and cost per piece stays at the volume tier.
Customization and options
The options customers tune most
The parts of the print for this stainless steel fitting that get adjusted: wall thickness bands, flange geometry, thread call-outs and the surface finish, with orders run as prototypes, pilot lots or scheduled call-offs.
Options for this stainless steel fitting already covered by the die are shown on the quote, so you are not charged twice for a feature the die already makes. The flange ring quote sets out quantities and price breaks side by side.
Specifications
| Item | Stainless Steel CNC Turned Shaft and Fittings |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – a manufacturability review comes back with the quotation; the approved drawing is kept as the controlled master. |
| Tooling | Die design and toolmaking stay in house, so die cost stays transparent, and first-article timing is measured from the tooling start date. |
| Samples | Sample approval is documented: dimensions, finish and material recorded for later comparison. |
| Materials | Standard stock: carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium, brass; material substitutes are proposed only with your written approval. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; the finish is inspected with the dimensional report on the first article. |
| Processing | Turning, milling and drilling sequenced to minimise handling and re-chucking; first articles verify the whole flow before the run is released. |
| Equipment | Turning centres fed from bar, with machining centres for milled features, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.01 mm on critical bores, confirms at DFM stage; finer bands confirmed from capability data before quoting. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, payment by T/T, L/C at sight or D/P; repeat orders reuse the approved first article. |
Packaging and delivery
The finish on this stainless steel fitting dictates how it is packed: the coating decides whether parts are interleaved, bagged or tray-packed, then cartons are sealed and palletised, with marks and documents as you specify.
