Aunov Tech supplies the Stainless Steel CNC Polished Union Fitting as a stainless steel component manufactured entirely in house. In service, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. The same floor forms, machines and inspects the part, so first-article dimensions hold through volume batches without a second supplier involved.
Product overview
What defines this stainless steel fitting is, material grade, wall uniformity and thread position, all held to the drawing and verified at first article.
Tooling and finishing for this stainless steel fitting run under one roof, so feasibility questions are answered on the shop floor, and nothing about the route depends on a third party.
How it is manufactured
Every stainless steel fitting follows the same routed path: The part is machined from bar or plate on CNC lathes and mills; threads are single-pointed or rolled and seats bored in one setup where possible.
Each run is logged against the drawing revision, so reorders match the samples you already approved.
Materials and finishing
Everything is drawn from a fixed stock list: SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze and this stainless steel fitting is costed in 304 / 316 stainless steel.
Coating and polishing are matched to the end use: zinc and nickel plating, chrome, anodising, powder coating and passivation. The agreed finish for this stainless steel fitting travels with the part number on every reorder.
Repeat mixed turned shafts, orders are measured against the approved sample, so neither material nor finish drifts between lots. Deviations on the mixed turned shafts, are reported before shipment rather than found on your assembly line.
Quality control and inspection
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, the CMM measures the first article dimension by dimension, and run inspections follow an agreed sampling plan. The mixed turned shafts, first article is measured on the CMM and thread gauges confirm class. Torque, leak and pressure tests are available where the assembly needs them, with certificates included in the shipment file.
Where the part is used
The stainless steel fitting is fitted into industrial equipment and general assembly work in both OEM and aftermarket supply.
Drawings for this stainless steel fitting are adapted across programmes, so the specification is set by the toughest of them, without a second tooling round.
Customization and options
Options changed most often
The options most often changed on this stainless steel fitting: material and coating for the duty, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, and how the order is released – sample, pilot run or scheduled call-off.
The quotation for this stainless steel fitting marks what the existing tooling can do, so you are not charged twice for a feature the die already makes. The mixed turned shafts, quotation records who owns the tooling.
Specifications
| Item | Stainless Steel CNC Polished Union Fitting |
|---|---|
| Brand | AUNOV |
| Designing | Send drawings, or send a sample to be measured – unusual walls, threads or tolerances are feasibility-checked first; changes are priced before they are made. |
| Tooling | Our toolroom covers die design, wire-cut EDM and maintenance, so tooling lead time stays under our control, and ownership is confirmed on the quotation. |
| Samples | Sample parts are measured and reported before submission, so the sample is retained as the master, and production starts only after your written sign-off. |
| Materials | Materials held include carbon steel, 304 / 316 stainless, aluminium and brass; the final grade is fixed with the drawing review. |
| Surface finish | Zinc, nickel or chrome plating, anodising, passivation or e-coat; finish thickness and adhesion checked on the first article. |
| Processing | CNC turning from bar or billet, concentricity held across operations; in-process checks sit between stages, not only at the end. |
| Equipment | CNC turning centres with bar feeders and 3-/4-axis machining centres, with CNC turning centres for secondary operations and CMM inspection. |
| Tolerance | +/-0.01 mm on turned and milled features; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | FOB, with DDP offered for EU and US addresses, T/T or L/C, with D/P accepted on repeat business; each volume tier carries its own quoted price. |
Packaging and delivery
For this stainless steel fitting, protection starts at the surface: each coating gets its own packing – interleaves, bags or trays, then sealed cartons are palletised for export, with documents and marks to your instruction.
